Hi,
As you said I did'nt used the chunks :
// all black material --> line material
SHLChunkPtr inkSHL = SHLChunk::create();
beginEditCP(inkSHL);
inkSHL->setVertexProgram(Utils::getFile("ink.vert"));
inkSHL->setFragmentProgram(Utils::getFile("ink.frag"));
endEditCP(inkSHL);
// model material -- here i wanted to archive a "toon" effect, thus the
"posterization" :)
SHLChunkPtr posterizeSHL = SHLChunk::create();
beginEditCP(posterizeSHL);
posterizeSHL->setVertexProgram(Utils::getFile("posterize.vert"));
posterizeSHL->setFragmentProgram(Utils::getFile("
posterize.frag"));
endEditCP(posterizeSHL);
So it looks like that : (geo is the geometry of my object)
outlineMat = SimpleMaterial::create();
PolygonChunkPtr backfaceCullingChunk = PolygonChunk::create();
beginEditCP(backfaceCullingChunk);
backfaceCullingChunk->setCullFace(GL_FRONT);
backfaceCullingChunk->setOffsetFill(true);
backfaceCullingChunk->setOffsetFactor(0.4);
backfaceCullingChunk->setOffsetBias(-10.0);
endEditCP(backfaceCullingChunk);
beginEditCP(outlineMat);
outlineMat->addChunk(backfaceCullingChunk);
outlineMat->setDiffuse(Color3f(0.5, 0.5, 0.5));
endEditCP(outlineMat);
beginEditCP(geo);
geo->setMaterial(outlineMat);
endEditCP(geo);
But it don't work, I have only a black shape.
What I would like is to have the extern border of my object drawn (the
outline),
but not draw the inside part of it, so that I see the others objects
behind.
Any idea?
Thanks,
Adrien

hi,
Utils::getFile() is just a simple method i wrote to read ascii data
from a file. It's not that important for the "outline" problem. You can
even use SimpleMaterials instead of ChunkMaterials, if you find it
easier ;)
cheers,

hi,
I tried that but I have some problem with the Utils::getFile.
What are these methods and the files, did you made them because
I can't find them in the OpenSG source...
