OpenSubdiv/examples/python

This folder defines a small demo application that requires PyQt, PyOpenGL, and the Python bindings for OpenSubdiv (which in turn require numpy and SWIG).

• main.py This is what you invoke from the command line. All calls to the osd module go here. Creates a QApplication and periodically pushes new VBO data into the renderer. (see below)
• renderer.py Defines the renderer; implements draw and init. All OpenGL calls are made in this file, and there's no dependency on Qt or osd.
• canvas.py Inherits from QGLWidget and calls out to the renderer object (see above)
• shaders.py Implements a miniature FX format by extracting named strings from a file and pasting them together
• simple.glsl Specifies the GLSL shaders for the demo using the miniature FX format
• utility.py Some linear algebra stuff to make it easier to use Modern OpenGL
• window.py Inherits from QMainWindow, instances a canvas object
• interactive.py Invoke this from the command line to spawn an alternative demo that has an interactive prompt.
• __init__.py Exports main into the package namespace to make it easy to run the demo from setup.py
