Hi I really start to wonder If anyone ever tried projective textures and had success. I'v read through the specifications and learnt that J3D1.3 introduced TexCoordGeneration.TEXTURE_4 and TexCoord4x for projective texturing. So far so good. But nothing in the specification tells me what the outcome texture will be is it 2D or 3D? Do I have to specify a 3D texture to get this working or can I also use a 2D texture? Meaning S/Q T/Q and not S/Q T/Q R/Q (Q is the fourth texture coordinate). In my examples as soon as I switch on TexCoordGeneration.TEXTURE_4 my Texturecoordinate before set as TEXTURE_2 seem to get completly out of the hand. Even when I set WRAP as Boundary-conditions for my Texture I don't see a thing. Which leads to following conclusion. Either all the texturecoordinates calculated are lying on one boundary or somewhere down below some errors are produced (which I don't get any notice of).
So If anyone has a working sample for this feature I would greatly appreciate some hints. Otherwise I see the only way out to calculate the texcoordinates myself through software and not taking use of the T&L hardware acceleration.
