Hi,
I had a *GLSL shader* in a scene with shadows, that use a *osg::**
shadowedScene* and it doesn't work. What is the problem?
Can I combine my GLSL shader and a shadowed scene??
I test it in the *osgshadow.cpp* example, i had this sample of code
(with the basic shader of phong, with no texture) :
...
while(arguments.read("--with-shader")) { withShader = true; }
if(withShader)
{
osg::ref_ptr<osg::Program> programObject = new osg::Program;
std::string repShad = "C:\\SHADERS\\";
osg::ref_ptr<osg::Shader> phongVertexObject = new osg::Shader(
osg::Shader::VERTEX );
osg::ref_ptr<osg::Shader> phongFragmentObject = new osg::Shader(
osg::Shader::FRAGMENT );
loadShaderSource( phongVertexObject.get(), repShad + "phong.vert" );
loadShaderSource( phongFragmentObject.get(), repShad + "phong.frag" );
programObject->addShader( phongVertexObject.get() );
programObject->addShader( phongFragmentObject.get() );
scene->getOrCreateStateSet()->setAttributeAndModes(programObject.get(),
osg::StateAttribute::ON);
}
...
My shader works, but it *cancels shadows*!! :( Help me!
Thanks in advance,
Mael.
