NVIDIA Scene Graph Software Development Kit (NVSG SDK) is an object-oriented programming library for creating scene graph-based applications.

Most scenegraphs do not support shading in an easy way (vertex and pixel shader). This was developed to integrate shading in a clean and easy way. It makes use of CgFX a meta file format for shaders. This abstraction allows to simply share shaders between different applications. The ViewerVR application shows how easy it is to drag and drop CgFX shaders onto the model and render the objects with shaders. It provides a comprehensive set of classes that developers can easily combine and extend to create fast and reliable graphics applications. The SDK also includes numerous tutorials with full source code to demonstrate how to use NVSG's features effectively.
