Regular Patterns

Create three different multi-layer regular pattern shaders.

1. In at least one of the shaders you should use the rmannotes functions rotate2d, odd/even, topolar2d, and whichtile (not necessarily all in the same shader.)
2. Each shader should have at least two pattern layers in addition to the background color(s).
3. Make creative use of boolean shapes.
4. Use different pattern frequencies in different layers.
5. Use interesting parameters to control visual attributes of each shader - not just pattern frequency and colors.
6. Render multiple 256x256 images of each shader , again using square.rib, showing the parameter range.
7. Don't use displacement or illumination for this assignment.

On your hw2 web page, show the rendered images demonstrating different parameter settings, show your shader code, and provide links to your three shader.sl files.
