**Rendering spectrum**: The book *Real-Time Rendering* mentions that methods for 3D rendering can be seen as lying on a spectrum, one extreme of which is *appearance reproduction* and the other *physics simulation*. Methods closer to trying to imitate the appearance try to simply focus on imitating the look of an object on the monitor that the actual 3D object would have in real life, without being concerned with *how* that look arises in real life (i.e. closer to the "faking" approach mentioned above) -- these may e.g. use image data such as photographs; these methods may rely on lightfields, photo [textures](texture.md) etc. The physics simulation methods try to replicate the behavior of light in real life -- their main goal is to solve the **[rendering equation](rendering_equation.md)**, still only more or less [approximately](approximation.md) -- and so, through internally imitating the same processes, come to similar visual results that arise in real world: these methods rely on creating 3D geometry (e.g. that made of triangles or voxels), computing light reflections and [global illumination](global_illumination.md). This is often easier to program but more computationally demanding. Most methods lie somewhere in between these two extremes: for example [billboards](billboard.md) and [particle systems](particle_system.md) may use a texture to represent an object while at the same time using 3D quads (very simple 3D models) to correctly deform the textures by perspective and solve their visibility. The classic polygonal 3D models are also usually somewhere in between: the 3D geometry and [shading](shading.md) are trying to simulate the physics, but e.g. a photo texture mapped on such 3D model is the opposite appearance-based approach ([PBR](pbr.md) further tries to shift the use of textures more towards the *physics simulation* end).

- by **order**:

- **object order**: The method iterates on objects and draws object by object, one after another. This results in pixels being drawn to "random" places on the screen and possibly already drawn pixels being [overdrawn](overdraw.md) with new pixels (though this can be further reduced). Typically requires a [frame buffer](frame_buffer.md) and [double buffering](double_buffering.md), often also [z-buffer](z_buffer.md) (or [sorting](sorting.md)), i.e. requires a lot of memory. This method is also a bit ugly but typically also faster than the alternative, so it is prevailing nowadays.

If you're a complete noob and are asking what the essence of 3D is or just how to render simple 3Dish pictures for your game without needing a [PhD](phd.md), here's the very basics. Yes, you can use some 3D engine such as [Godot](godot.md) that has all the 3D rendering preprogrammed, but you you'll surrender to [bloat](bloat.md), you won't really know what's going on and your ability to tinker with the rendering or optimizing it will be basically zero... AND you'll miss on all the [fun](fun.md) :) So here we just foreshadow some concepts you should start with if you want to program your own 3D rendering.

The absolute basic thing in 3D is probably **[perspective](perspective.md)**, or the concept which says that "things further away look smaller". This is basically the number one thing you need to know and with which you can make simple 3D pictures, even though there are many more effects and concepts that "make pictures look 3D" and which you can potentially study later (lighting, shadows, [focus and blur](depth_of_field.md), [stereoscopy](stereo.md), [parallax](parallax.md), visibility/obstruction etc.). { It's probably possible to make something akin "3D" even without perspective, just with [orthographic](ortho.md) projection, but that's just getting to details now. Let's just suppose we need perspective. ~drummyfish }

**Assembly is NOT a single language**, it differs for every architecture, i.e. every model of CPU has potentially different architecture, understands a different machine code and hence has a different assembly (though there are some standardized families of assembly like x86 that work on wide range of CPUs); therefore **assembly is not [portable](portability.md)** (i.e. the program won't generally work on a different type of CPU or under a different [OS](os.md))! And even the same kind of assembly language may have several different [syntax](syntax.md) formats which may differ in comment style, order of writing arguments and even instruction abbreviations (e.g. x86 can be written in [Intel](intel.md) and [AT&T](at_and_t.md) syntax). For the reason of non-portability (and also for the fact that "assembly is hard") you shouldn't write your programs directly in assembly but rather in a bit higher level language such as [C](c.md) (which can be compiled to any CPU's assembly). However you should know at least the very basics of programming in assembly as a good programmer will come in contact with it sometimes, for example during hardcore [optimization](optimization.md) (many languages offer an option to embed inline assembly in specific places), debugging, reverse engineering, when writing a C compiler for a completely new platform or even when designing one's own new platform. **You should write at least one program in assembly** -- it gives you a great insight into how a computer actually works and you'll get a better idea of how your high level programs translate to machine code (which may help you write better [optimized](optimization.md) code) and WHY your high level language looks the way it does.

**OK, but why doesn't anyone make a portable assembly?** Well, people do, they just usually call it a [bytecode](bytecode.md) -- take a look at that. [C](c.md) is portable and low level, so it is often called a "portable assembly", though it still IS significantly higher in abstraction and won't usually give you the real assembly vibes. [Forth](forth.md) may also be seen as close to such concept. ACTUALLY [Dusk OS](duskos.md) has something yet closer, called [Harmonized Assembly Layer](hal.md) (see https://git.sr.ht/~vdupras/duskos/tree/master/fs/doc/hal.txt).

Copyright (better called *copyrestriction* or *copywrong*) is one of many types of so called "[intellectual property](intellectual_property.md)" (IP), a legal concept that allows "ownership", i.e. restriction, [censorship](censorship.md) and artificial [monopoly](monopoly.md) on certain kinds of [information](information.md), for example prohibition of sharing or viewing useful [information](information.md) or improving [art](art.md) works. Copyright specifically allows the copyright holder (not necessarily the author) a monopoly (practically absolute power) over [art](art.md) creations such as images, songs or texts, which also include source code of computer [programs](program.md). Copyright is a [capitalist](capitalism.md) mechanism for creating [artificial scarcity](artificial_scarcity.md), enabling censorship and elimination of the [public domain](public_domain.md) (a pool of freely shared works that anyone can use and benefit from). Copyright is not to be confused with [trademarks](trademark.md), [patents](patent.md) and other kinds of "intellectual property", which are similarly [harmful](harmful.md) but legally different. Copyright is symbolized by C in a circle or in brackets: (C), which is often accompanies by the phrase "all rights reserved".

When someone creates something that can even remotely be considered artistic expression (even such things as e.g. a mere collection of already existing things), he automatically gains copyright on it, without having to register it, pay any tax, announce it or let it be known anywhere in any way. He then practically has a full control over the work and can successfully sue anyone who basically just touches the work in any way (even unknowingly and unintentionally). Therefore **any work (such as computer code) without a [free](free_software.md) license attached is implicitly fully "owned" by its creator** (so called "all rights reserved") and can't be used by anyone without permission. It is said that copyright can't apply to ideas (ideas are covered by [patents](patent.md)), only to expressions of ideas, however that's [bullshit](bs.md), the line isn't clear and is arbitrarily drawn by judges; for example regarding stories in books it's been established that the story itself can be copyrighted, not just its expression (e.g. you can't rewrite the [Harry Potter](harry_potter.md) story in different words and start selling it).

For debugging your program it may greatly help to make **debugging builds** -- you may pass flags to your compiler that make the program better for debugging, e.g. with [gcc](gcc.md) you will likely want to use `-g` (generate debug symbols) and `-Og` (optimize for debugging) flags. Without this debuggers will still work but may be e.g. unable to tell you the name of function inside which the program crashed etc.

A good enough solution to a problem is a solution that solves the problem satisfyingly (not necessarily precisely or completely) while achieving minimal cost (effort, implementation time etc.). This is in contrast to looking for a better solutions for a higher cost, which we might call an [overkill](overkill.md). For example a word-for-word translation of a text is a primitive way of translation, but it may be good enough to understand the meaning of the text; in many climates a tent is a good enough accommodation solution while a luxury house is a solution of better quality (more comfortable, safe, ...) for a higher cost.

This is contrasted with an [overkill](overkill.md), a solution that's "too good" (for a higher cost).

In technology we are often times looking for good enough solution to achieve [minimalism](minimalism.md) and save valuable resources (computational resources, programmer time etc.). It rarely makes sense to look for solutions that are more expensive than they necessarily need to be, however in the context of [capitalist software](capitalist_software.md) we see this happen many times as a part of killer feature battle and also driving prices artificially up for economic reasons (e.g. increasing the cost of maintenance of a software eliminates any competition that can't afford such cost). An example of this is the trend in smartphones to have 4 and more physical cameras. This is only natural in [capitalism](capitalism.md), we see the tendency for wasting resources everywhere. This of course needs to be stopped.

Here are some of the ideas/movements/ideologies and people whose ideas inspired less retarded society. It has to be stressed we never follow [people](hero_culture.md), only their ideas -- mentioning people here simply means we follow SOME of their ideas. Also keep in mind mentioning an idea here doesn't mean fully embracing it, we most likely only adopted some parts of it.
|
||||||
|
|
||||||
|
- **[anarcho pacifism](anpac.md)**: Rejecting force and hierarchy of one living being dominating and oppressing another.
|
||||||
|
- **Buddha, [Buddhism](buddhism.md)**: Attaining freedom through letting go, focusing on the spiritual rather than the material, living non violently.
|
||||||
|
- **[communism](communism.md), [anarcho communism](ancom.md), [socialism](socialism.md)**: Sharing, equality, rejection of property and money, focus on people at large.
|
||||||
|
- **[Diogenes](diogenes.md), [cynicism](cynicism.md)**: Rejecting conformity, wealth, power, fame, materialistic needs, embracing simple living in harmony with nature.

|
||||||
|
- **[Jesus](jesus.md), [Christianity](christianity.md)**: Teaching [love](love.md) towards everyone, even those who hurt us, practicing non violence, helping, sharing and compassion, opposing materialist values, valuing the spiritual, being ready to die for one's beliefs.
|
||||||
|
- **[minimalism](minimalism.md), [KISS](kiss.md), [suckless](suckless.md), [less is more](less_is_more.md), [worse is better](worse_is_better.md), [Unix philosophy](unix_philosophy.md), ...**: Way towards [freedom](freedom.md), both practical and spiritual, letting go of the unneeded, most essential design principle, beauty and elegance.
|
||||||
|
- **[primitivism](primitivism.md)**: Related to minimalism, letting go of unnecessary and focus on what matters the most, living close to nature.
|
||||||
|
- **[Richard Stallman](rms.md), [free software](free_software.md), [free culture](free_culture.md)**: Opposition of "[intellectual property](intellectual_property.md)", focus on ethics, freedom and technology/art serving the people.

||||||
|
- **[Sikhism](sikhism.md)**: Serving free food to all people as part of Langar, example of [selflessness](selflessness.md).

In late stage capitalism this is not possible as an "ethical" marketing is a non effective marketing. Deciding to drop the most efficient weapons in the market warfare will only lead to the company losing customers to competition who embraces the unethical means, eventually going bankrupt and disappearing, leaving the throne to the bad guys. Laws will not help as laws are made to firstly favor the market, corporations pay full time lobbyists and law makers themselves are owners of corporations. Even if some small law against "unethical marketing" passes, the immense force and pressure of all the strongest corporations will work 24/7 on reverting the law and/or finding ways around it, legal or illegal, ethical or unethical.

This is a kind of space-time tradeoff. Consider e.g. `while (a) if (b) func1(); else func2();` -- if *b* doesn't change inside the loop, you can rewrite this as `if (b) while (a) func1(); else while (a) func2();`.

E.g. imagine you store your game sprites as a continuous array of images in RAM and your program internally precomputes a table that says where each image starts -- here you can either use pointers (which say directly the memory address of each image) or indices (which say the offset from the start of the big image array): using indices may be better here as the table may potentially be smaller (an index into relatively small array doesn't have to be able to keep any possible memory address) and the table may even be stored to a file and just loaded next time (whereas pointers can't because on next run the memory addresses may be different), however you'll need a few extra instructions to access any image (adding the index to the array pointer), which will however most definitely be negligible.

So prefer using switch when you have many conditions to check. Switch also allows hacks such as label fall through which may help some optimizations.

Do the same with the `switch` statement -- even though switch typically gets compiled to a table of jump addresses, in which case order of the cases doesn't matter, it may also get compiled in a way similar to the if sequence (e.g. as part of size optimization if the cases are sparse) and then it may matter again.

## Automatic Optimization

TODO

Automatic optimization is typically performed by the compiler; usually the programmer has the option to tell the compiler how much and in what way to optimize (no optimization, mild optimization, aggressive optimization, optimization for speed, size; check e.g. the man pages of [gcc](gcc.md) where you can see how to turn on even specific types of optimizations). Some compilers perform extremely complex reasoning to make the code more efficient, the whole area of optimization is a huge science -- here we'll only take a look at the very basic techniques. We see optimizations as transformations of the code that keep the semantics the same but minimize or maximize some measure (e.g. execution time, memory usage, power usage, network usage etc.). Automatic optimizations are usually performed on the intermediate representation (e.g. [bytecode](bytecode.md)) as that's the ideal way (we only write the optimizer once), however some may be specific to some concrete instruction set -- these are sometimes called *peephole* optimizations and have to be delayed until code generation.
|
||||||
|
|
||||||
|
The following are some common methods of automatic optimization (also note that virtually any method from the above mentioned manual optimizations can be applied if only the compiler can detect the possibility of applying it):
|
||||||
|
|
||||||
|
{ Tip: man pages of gcc or possibly other compilers detail specific optimizations they perform under the flags that turn them on, so see these man pages for a similar overview. ~drummyfish }

- **Replacing instructions with faster equivalents**: we replace an instruction (or a series of instructions) with another one that does the same thing but faster (or with fewer instructions etc.). Typical example is replacing multiplication by power of two with a bit shift (e.g. `x * 8` is the same as `x << 3`).
|
||||||
|
- **Inlining**: a function call may usually (not always though, consider e.g. [recursion](recursion.md)) be replaced by the function code itself inserted in the place of the call (so called inlining). This is faster but usually makes the code bigger so the compiler has to somehow judge and decide when it's worth to inline a function -- this may be affected e.g. by the function size (inlining a short function won't make the code that much bigger), programmer's hints (`inline` keyword, optimize for speed rather than size etc.) or guesstimating how often the function will be called. Function that is only called in one place can be safely inlined.
|
||||||
|
- **Loop unrolling**: dupliates the body of a loop, making the code bigger but increasing its speed (a condition check is saved). E.g. `for (int i = 0; i < 3; ++i) func();` may be replaced with `func(); func(); func();`. Unrolling may be full or just partial.
|
||||||
|
- **[Lazy](lazy_eval.md) evaluation/short circuit/test reordering**: the principles of lazy evaluation (evaluate function only when we actually need it) and short circuit evaluation (don't further evaluate functions when it's clear we won't need them) may be auto inserted into the code to make it more efficient. Test reordering may lead to first testing simpler things (e.g. equality comparison) and leaving complex tests (function calls etc.) for later.
|
||||||
|
- **Algebraic laws, expression evaluation**: expressions may be partially preevaluated and manipulated to stay mathematically equivalent while becoming easier to evaluate, for example `1 + 3 + 5 * 3 * x / 6` may be transformed to just `4 + 5 * x / 2`.
|
||||||
|
- **Removing instructions that cancel out**: for example in [Brainfuck](brainfuck.md) the series of instructions `+++--` may be shortened to just `+`.
|
||||||
|
- **Removing instructions that do nothing**: generated code may contain instructions that just do nothing, e.g. NOPs that were used as placeholders that never got replaced; these can be just removed.
|
||||||
|
- **Register allocation**: most frequently used variables should be kept in CPU registers for fastest access.
|
||||||
|
- **Removing branches**: branches are often expensive due to not being CPU pipeline friendly, they can sometimes be replaced by a branch-free code, e.g. `if (a == b) c = 1; else c = 0;` can be replaced with `c = a == b;`.
|
||||||
|
- **Memory alignment, reordering etc.**: data stored in memory may be reorganized for better efficiency, e.g. an often accessed array of bytes may actually be made into array of ints so that each item resides exactly on one address (which takes fewer instructions to access and is therefore faster). Data may also be reordered to be more [cache](cache.md) friendly.
|
||||||
|
- **Generating [lookup tables](lut.md)**: if the optimizer judges some function to be critical in terms of speed, it may auto generate a lookup table for it, i.e. precompute its values and so sacrifice some memory for making it run extremely fast.
|
||||||
|
- **Dead code removal**: parts of code that aren't used can be just removed, making the generated program smaller -- this includes e.g. functions that are present in a [library](library.md) which however aren't used by the specific program or blocks of code that become unreachable e.g. due to some `#define` that makes an if condition always false etc.
|
||||||
|
- **[Compression](compression.md)**: compression methods may be applied to make data smaller and optimize for size (for the price of increased CPU usage).

Permacomputing is a new term invented by [Viznut](viznut.md), it's inspired by the term *[permaculture](permaculture.md)* and means something like "sustainable, ecological minimalist computing"; see [permacomputing wiki](permacomputing_wiki.md).

**Downsides** of Pokitto are that the community is an [open source](open_source.md) community rather than [free software](free_software.md) one, purists like us will find they lean towards [bloated](bloat.md) solutions even though the technical limitation of the console largely prevent their implementation. The web forums runs on [discourse](discourse.md) and requires [JavaScript](js.md) for interactivity. [Discord](discord.md) is also actively used for communication, even though some community members bridged it to free alternatives. The official library is relatively bloated and even contains some small pieces of unlicensed code from the [MCU](mcu.md) manufacturer -- they are very simple assembly snippets that may be easily replacaeble, but we should be cautious even about this. Anyway, a reasonably dedicated programmer might create a suckless Pokitto library without greater problems.

**Can you become a good programmer when you're old?** Well, as with everything to become a SERIOUSLY good programmer you should have probably started before the age of 20, the majority of the legend programmers started before 10, it's just like with sports or becoming an excellent musician. But with enough enthusiasm and endurance you can become a pretty good programmer at any age, just like you can learn to play an instrument or run marathon basically at any age, it will just take longer and a lot of energy. You don't even have to aim to become very good, becoming just average is enough to write simple gaymes and have a bit of fun in life :) Just don't try to learn programming because it seems cool, because you want to look like movie haxor, gain followers on youtube or because you need a job -- if you're not having genuine fun just thinking before sleep about how to swap two variables without using a temporary variable, programming is probably not for you. **Can you become a good programmer if you're black or [woman](woman.md)?** No. :D Ok, maybe you can, but all the above applies, don't do it for politics or money or followers -- if you become a seriously based programmer (from [LRS](lrs.md) point of view) of unlikely minority, we'll be more than happy to put an apology here, in ALL CAPS and bold letters :) Hopefully this will inspire someone...

So **program, program and program**, live by programming, look for ways of using programming in what you're already doing, try to automatize anything you do, think about programming before sleep etc. If you can, **contribute to some project**, best if you can help your favorite [FOSS](foss.md) program -- try this at least once as being in the company of the experienced just teaches you like nothing else, a month spent contributing to a project may be worth a year of just reading books.
