Well I took it upon myself to read about linear interpolation today, since I found some 'lerp' code in the Irrlicht engine and realised how useful it is in the domain of computer graphics.
I almost completely understand it too
Anyway, I read wikipedia's article on bilinear interpolation and sort of understood that too... but what can you use it for in computer graphics? Can you use it in computer graphics? There's a pretty picture in the article.
I googled 'bilinear interpolation in computer graphics'... what the hell is a 'pyramid filter'? Wikipedia has no answers and the google results for that confuse me.
