Hi J.P., Finally I can figure out a way so I don't need the signed int. Anyway, I think my really problem is that by some reason, the texture is not uploading correctly to the GPU :S
In my OGL code I have: Code: glGenTextures(1, &(this->triTableTex)); glActiveTexture(GL_TEXTURE2); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, this->triTableTex); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_R, GL_CLAMP_TO_EDGE); glTexImage2D( GL_TEXTURE_2D, 0, GL_ALPHA16I_EXT, 16, 256, 0, GL_ALPHA_INTEGER_EXT, GL_INT, &triTable); and in osg I do: Code: osg::Texture2D *tex = new osg::Texture2D(); tex->setFilter( osg::Texture2D::MIN_FILTER, osg::Texture2D::NEAREST ); tex->setFilter( osg::Texture2D::MAG_FILTER, osg::Texture2D::NEAREST ); tex->setWrap( osg::Texture2D::WRAP_S , osg::Texture2D::CLAMP_TO_EDGE ); tex->setWrap( osg::Texture2D::WRAP_T , osg::Texture2D::CLAMP_TO_EDGE ); tex->setWrap( osg::Texture2D::WRAP_R , osg::Texture2D::CLAMP_TO_EDGE ); //tex->setDataVariance( osg::Object::DYNAMIC ); unsigned char *cc = new unsigned char[256*16]; for ( int i = 0 ; i < 256 ; i++) for ( int ii = 0 ; ii < 16 ; ii++) { //cc[ ii + i*16 ] = triTable[i][ii]; cc[ ii + i*16 ] = 127; } osg::Image *i = new osg::Image(); i->setImage( 16 , 256 , 0 , GL_ALPHA16I_EXT , GL_ALPHA_INTEGER_EXT , GL_INT , (unsigned char *)&triTable , osg::Image::NO_DELETE ); tex->setImage( i ); brickState->setTextureAttributeAndModes(1,tex,osg::StateAttribute::ON); I'm just setting all the values to 127 so I can check in the GPU if the texture is uploaded to the geometry shader. I need this values to work in the GPU, as I'm using it for an Marching Cubes Algorithm based. Do you think I need to do something else? Thanks!
