Hello,

Im have a question about bilinear interpolation.

Do i use the coords for texture coords after i have done a bilinear interpolation on the texturemapping?

Also, i have seen that opengl does somesort of bilinear interpolation with hint, but it isnt exact.

Is there a written code algoritm for bilinear interpolation?

I don't think there's an official C algorithm but if you know what "lerping" means it should be no problem at all in the case you need to do it in software.

As for the rest, I really cannot understand the sense of the message...
