Hi all,
I'm currently working on integrating RenderMonkey Glass shader into
OpenSceneGraph. There, i need to pass cubemap as uniform. For creating cubemap
i'm using osg::TextureCubeMap class. It seems like glsl doesn't process
texture as it should.
Code:
osg::ref_ptr<osg::TextureCubeMap> cubemap = new osg::TextureCubeMap;
osg::Image* imagePosX = osgDB::readImageFile("images/cm_right.tga");
osg::Image* imageNegX = osgDB::readImageFile("images/cm_left.tga");
osg::Image* imagePosY = osgDB::readImageFile("images/cm_bottom.tga");
osg::Image* imageNegY = osgDB::readImageFile("images/cm_top.tga");
osg::Image* imagePosZ = osgDB::readImageFile("images/cm_front.tga");
osg::Image* imageNegZ = osgDB::readImageFile("images/cm_back.tga");
if (imagePosX && imageNegX && imagePosY && imageNegY && imagePosZ &&
imageNegZ)
{
cubemap->setImage(osg::TextureCubeMap::POSITIVE_X, imagePosX);
cubemap->setImage(osg::TextureCubeMap::NEGATIVE_X, imageNegX);
cubemap->setImage(osg::TextureCubeMap::POSITIVE_Y, imagePosY);
cubemap->setImage(osg::TextureCubeMap::NEGATIVE_Y, imageNegY);
cubemap->setImage(osg::TextureCubeMap::POSITIVE_Z, imagePosZ);
cubemap->setImage(osg::TextureCubeMap::NEGATIVE_Z, imageNegZ);
cubemap->setWrap(osg::Texture::WRAP_S, osg::Texture::CLAMP_TO_EDGE);
cubemap->setWrap(osg::Texture::WRAP_T, osg::Texture::CLAMP_TO_EDGE);
cubemap->setWrap(osg::Texture::WRAP_R, osg::Texture::CLAMP_TO_EDGE);
cubemap->setFilter(osg::Texture::MIN_FILTER,
osg::Texture::LINEAR_MIPMAP_LINEAR);
cubemap->setFilter(osg::Texture::MAG_FILTER, osg::Texture::LINEAR);
}
osg::StateSet* stateset = model->getOrCreateStateSet();
osg::Shader* vertexShader = new osg::Shader( osg::Shader::VERTEX );
osg::Shader* fragmentShader = new osg::Shader( osg::Shader::FRAGMENT );
vertexShader->loadShaderSourceFromFile( "winglass.vert" );
fragmentShader->loadShaderSourceFromFile( "winglass.frag" );
osg::Program* program = new osg::Program;
program->addShader( vertexShader );
program->addShader( fragmentShader );
stateset->setAttributeAndModes( program, osg::StateAttribute::ON );
osg::Uniform* environment = new osg::Uniform(osg::Uniform::SAMPLER_CUBE,
"Environment");
environment->set(cubemap.get());
stateset->addUniform( environment );
What is wrong?
Kind regards,
