the situation : i want to create a big blurry texture for my whole outdoor map. therefore, i calculate for every pixel the position where its corresponding landscape point is.
now i end up on a triangle. i know it's textures, and the density of each texture at each vertex, which is stored in its color.
maybe you know the method : http://www.delphi3d.net/articles/vie...terraintex.htm
well, for the blurry texture, i need to calculate a specific pixels color. in others words : i got 3 vertices, 3 colors. how to calclate a color on a specific point somewhere on this triangle ?
