 This kind of art used to be a great part of the culture of earliest [Internet](internet.md) communities for a number of reasons imposed largely by the limitations of old computers -- it could be created easily with a text editor and saved in pure text format, it didn't take much space to store or send over a network and it could be displayed on text-only displays and terminals. The principle itself predates computers, people were already making this kind of images with type writers. Nevertheless the art survives even to present day and lives on in the hacker culture, in [Unix](unix.md) communities, on the [Smol Internet](smol_internet.md) etc. ASCII diagram may very well be embedded e.g. in a comment in a source code to explain some spatial concept -- that's pretty [KISS](kiss.md). We, [LRS](lrs.md), highly advocate use of ASCII art whenever it's [good enough](good_enough.md).

 Bilinear interpolation (also bilinear filtering) is a simple way of creating a smooth transition ([interpolation](interpolation.md)) between [discrete](discrete.md) samples (values) in 2D, it is a [generalization](generalization.md) of [linear interpolation](lerp.md) to 2 dimensions. It is used in many places, popularly e.g. in 3D [computer graphics](graphics.md) for [texture](texture.md) filtering; bilinear interpolation allows to upscale textures to higher resolutions (i.e. compute new pixels between existing pixels) while keeping their look smooth and "non-blocky" (even though blurry). On the scale of quality vs simplicity it is kind of a middle way between a simpler [nearest neighbour](nearest_neighbour.md) interpolation (which creates the "blocky" look) and more complex [bicubic interpolation](bicubic.md) (which uses yet smoother curves but also requires more samples). Bilinear interpolation can further be generalized to [trilinear interpolation](trilinear.md) (in computer graphics trilinear interpolation is used to also additionally interpolate between different levels of a texture's [mipamap](mipamp.md)) and perhaps even bilinear [extrapolation](extrapolation.md). Many frameworks/libraries/engines have bilinear filtering built-in (e.g. `GL_LINEAR` in [OpenGL](ogl.md)).

+*The above image is constructed by applying bilinear interpolation to the four corner values.*
+
 The principle is simple: first linearly interpolate in one direction (e.g. horizontal), then in the other (vertical). Mathematically the order in which we take the dimensions doesn't matter (but it may matter practically due to rounding errors etc.).
 
 Example: let's say we want to compute the value *x* between the four following given corner values:
