[4/17/96]

• updated stochastic patterns section; particularly turbulence discussion and shaders now use gradual clamped turbulence

[4/15/96]

• use of RManNotes function blend() instead of mix; surface_opac and layer_opac now colors (previously floats).

[3/27/96]

• new look; links changed;
• updated rsl emacs mode (color highlighting, change rib filenames and include directories);
• shaders updated to use a header file called rmannotes.sl which contains all convenience functions described in the notes. the functions are all implemented as macros (formerly user functions);
• variable naming conventions changed (e.g. ink now called layer_color) to hopefully be less confusing;
• def of pulse and use of smoothstep modified to keep filter on micropolygon for constant shading;
• shader basics section simplified; all sections edited for correctness;
• shaders in regular patterns no longer use white as a layer color so that you can see something if Cs is white;
• search engine added.
