rmannotes.sl - File that contains many useful macros for use in your RenderMan shaders.

RIBS:

atmostest.rib Simple RIB file to test atmosphere effects.

hw02.rib - the rib file you should use to render all images for homework #2.

windowlight.rib RIB file used to test a texture-shadowed light in atmosphere.

Shaders:

aliasnoise.sl This noise shader makes an attempt to limit the frequencies of the noise based on a sample width, computed from the rate of change of the shaded point in shader space.

blendfog.sl This atmosphere shader simply blends the surface color with some atmosphere color depending on distance.

bospot.sl The light shader I wrote that incorporates shadow mapping, coloring shadows (something other than black), and using a texture for a slide-projector effect.

celtic.sl Uses the ptlined() function to draw a repeatable celtic braid pattern. Uses modified input color Cs. Create many user-definable parameters for linewidth, frequency, and switching between cartesian and polar coordinates.

emboss.sl - A shader specified in the documentation for homework #0, but was unavailable. This is a quick version I came up with for use in the Chapter 4 tutorials.

land.sl Utilizes layering for rock, grass, snow, beach, and water colors. Interpolations based on elevation and slope. For those of you who want to play with this shader, the RIB file for a terrain surface can be found here.

my_atmos.sl The environment shader used to create the light-through-the-window effect shown in class.

rings.sl Uses a spline function to blend color ramp with input color Cs. Use on a disk surrounding your planet!

woodcut.sl The latest incarnation of my woodcut shader, this incorporates the color spline remapping for that lovely sepia tone!

teach.sl.tar This archive contains the series of shaders that was used to demonstrate layering, tiling, and the use of multiple shading models in one shader. All shaders compile to teach.slo.
