 The above mentioned methods can be generalized to more dimensions (the number of dimensions are equal to the number of interpolation parameters) -- we encounter this a lot e.g. in [computer graphics](graphics.md) when upscaling [textures](texture.md) (sometimes called texture filtering). 2D nearest neighbor interpolation creates "blocky" images in which [pixels](pixel.md) simply "get bigger" but stay sharp squares if we upscale the texture. Linear interpolation in 2D is called [bilinear interpolation](bilinear.md) and is visually much better than nearest neighbor, [bicubic interpolation](bicubic.md) is a generalization of cubic interpolation to 2D and is yet smoother that bilinear interpolation.
 
+TODO: simple C code pls, maybe linear interpolation without floats
