Another way to you could do this is you want to keep the program around to reuse later
Is to remove the shaders from the program m_rvShadeProgram->removeShader(m_mainVertexShader) To re-enable do m_rvShadeProgram->AddShader(m_mainVertexShader) This works nice for our usage, note you will need to start the m_mainVertexShader with a reference count of 1 before do the first add.. More than one way to skin a cat as the saying goes ;) Gordon __________________________________________________________ Gordon Tomlinson Email : gtomlinson @ overwatch.textron.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Art Tevs Sent: Thursday, August 28, 2008 5:14 AM To: OpenSceneGraph Users Subject: Re: [osg-users] Disable Shader You can also just add an empty program to the StateSet. Something like this: ss->setAttributeAndModes(new osg::Program()); This will bind a program object which will call glUseProgram(0) on the next apply, which is in fact the same as disable a shader program.
