Exploring the Third Dimension
You’ve seen how to take a point in three-dimensional space and project it onto the screen so that it can be rendered. Projection is only part of the process of rendering a 3D scene; you also need to manipulate the points in the game to update the scene from frame to frame. This chapter introduces the matrix, which is a kind of mathematical shortcut used to manipulate the position and orientation of objects in a game.
You will also learn how to use Pygame with OpenGL to access the 3D graphics capabilities of your graphics card to create impressive visuals, on par with commercial games.
