8_The Scene Graph
This lesson explains the scene graph which is a useful structure for 3D scenes that contain many objects and relationships. In the 3D Objects section we int...
7_Enter the Matrix
In this lesson, we apply what we learned about calculating geometric transformations to build a Matrix class and integrate it with our CG framework.
6_Geometric Transformations
This lesson explains the mathematical concepts behind matrix calculations for common transformations in computer graphics including scaling, rotation, transl...
5_Vectors and Matrices
In this lesson we review the mathematical foundations that make geometric transformations possible in computer graphics: vectors and matrices.

4_Animation and Interactivity
In this lesson, we introduce uniform data for use in animations and keyboard events for greater interaction with the application.
3_Drawing Shapes
In this lesson, we add a class to our framework to simplify the use of vertex buffers and then use the class to draw shapes with multiple vertices and colors.
2_Windows and Points
This lesson introduces the basic framework components for creating an application window and rendering a point on the screen.
1_Getting Started
OpenGL programming in Python requires a little effort to set up the development environment. This post tells you how.
