3Delight & Pixie
Several minor changes have been made to the way that Cutter generates the
RIB files for these renderers. The "Rib Options" under the Options tab of
the Rman Tools floating palette (figure 2) provides three ways that Cutter
can declare, or not declare, the parameter values of a shader. For example,
suppose we have a shader called pity with a single float parameter named sad.
With inline datatypes chosen the text for this shader would be "inserted"
into a RIB file as,
Surface "pity" "float sad" 1.0
With declare datatypes chosen the text for this shader would be "inserted"
into a RIB file as,
Declare "sad" "float"
Surface "pity" "sad" 1.0
With omit datatypes chosen the text for this shader would be "inserted"
into a RIB file as,
Surface "pity" "sad" 1.0
RIB files generated for Pixar's prman renderer have always, by default, used
the last option. Now RIB files for 3Delight and Pixie also use omit datatypes.
There is, however, a problem with version 1.3.26 of 3Delight. On windows, Cutter is
able to read the system shaders that ship with this product.
