Transparent pyramid using custom nodes

CustomNodePyramid - This example shows how to use custom nodes with .

DESCRIPTION:

This example demonstrates how to render a transparent shape - here a pyramid - using the different types of custom nodes. It shows that, to add transparency to a OpenGL custom node, you need to encapsulate the handling of transparency in an Inventor custom node, and do a forward traversal on an OpenGL custom node that will contain the actual draw calls
