We import the math modules (for angle calculations used to control the view based on mouse movements). We also import the demo module, which just provides the path to the shaders and textures in this example.
We start by defining some key elements that will be used by pi3d to generate and display our object. The space in which we shall place our object is the pi3d.Display object; this defines the size of the space and initializes the screen to generate and display OpenGL ES graphics.
Next, we define a pi3d.Camera object, which will allow us to define how we view the object within our space. To render our object, we define a texture to be applied to the surface and a shader that will apply the texture to the object. The shader ...
