Hi! (again)
I'w working on SGI Indigo2 impact IRIX 6.5 & java 3D 1.1.3, and it seems
there's some problems with the transparent texture.
I have
- a white plane
- a texture with some pixels colored and some transparent
I would like my plane to have the colors of the texture. But when I use
- modulate, the result is semi-transparent and dark for all the pixels,
It's not the colors of my texture
- blend, the result is completly white
- decal, I can see the edges of my texture, but it's really white. It's
not the colors of my texture
did I miss sth? or is it a specific problem with SGI and texture. (I
mentioned that examples
didn't work very well, "examples/texture/TextureModeApp.java")
thanks in advance
