Detailed Description

Holds the system parameters to be passed to all shader callbacks. This is a legacy structure returned by the IRTSExecutionState::GetSystemParams function.

Parameters:

	m_lNbParams	Number of parameters
	m_lAppID	Application ID
	m_lRTSVersion	Realtime shader protocol version.
	m_lContext	Uniquely identifies the viewport during a Softimage session. Each viewport (regular or object view) has an XGS context associated with it. m_lContext is a handle to the context object cast to a LONG
	m_pShaderHandle	Shader instance handle (CRef handle to the Shader object). You can use the C++ API to access it.
	m_pObjectHandle	Deprecated v7.0. For RTS v3.0 shaders you can get the object directly via IRTSExecutionState::GetPrimitive
	m_pMaterialHandle	Deprecated v7.0. For RTS v3.0 shaders you can get the material directly via IRTSExecutionState::GetMaterial
	m_pGS	Handle to the graphic system (CRef handle to the GraphicSequencer object). You can use the C++ API to access it.
	m_pGLExt	The OpenGL extension wrapper flags indicate whether a particular OpenGL extension is used. Simply test the appropriate field in that structure. For example, if you want to test whether your hardware supports the GL_ARB_multitexture extension, then simply check if m_pGS->_GL_ARB_multitexture is set to TRUE.
	m_pGLExtFuncs	The OpenGL extension wrapper functions can be called directly from that structure. For example, if you want to call the glClientActiveTextureARB extension function, just use m_pGLExtFuncs->glClientActiveTextureARB.
	m_lShaderFlags	Shader flags. See Shader Flag Defines .
	m_lObjectFlags	Object flags. See Object Flag Defines .
	m_m4x4ObjectPose	The object pose is a 4x4 matrix containing the global transformation of the object.
	m_SceneData	The scene data is a structure that contains camera and light information. See tagXSI_RTS_SceneData.
