Description<br />
sets the current opacity to color.<br />
sets additional implementation-specific options.<br />
sets the current orientation to be either left-handed<br />
or right-handed.<br />
concatenates a perspective transformation onto the<br />
current transformation.<br />
performs antialiasing by filtering the geometry<br />
(or supersampling) and then sampling at pixel<br />
locations.<br />
sets the effective sampling rate in the horizontal<br />
and vertical directions<br />
sets the amount computed image values are allowed<br />
to deviate from the true image values.<br />
sets the type of projection and marks the current<br />
coordinate system before projection as the camera<br />
coordinate system.<br />
sets the quantization parameters for colors or<br />
depth.<br />
<strong>The</strong> relative level of detail scales the results of all<br />
level of detail calculations.<br />
causes the current orientation to be toggled.<br />
concatenates a rotation of angle degrees about the<br />
given axis onto the current transformation.<br />
RiScale (sx, sy, sz) concatenates a scaling onto the current<br />
transformation.<br />

RiShadingInterpolation ()<br />
RiShadingRate (size)<br />
RiShutter (min, max)<br />
RiSides (sides)<br />
RiSkew (angle, dx1, dy1, dz1,<br />
dx2, dy2, dz2)<br />
defines a rectangle in the image plane that gets<br />
mapped to the raster coordinate system and that<br />
corresponds to the display area selected.<br />
controls how values are interpolated between<br />
shading samples (usually across a polygon).<br />
sets the current shading rate to size.<br />
sets the times at which the shutter opens and<br />
closes.<br />
If sides is 2, subsequent surfaces are considered<br />
two-sided and both the inside and the outside of<br />
the surface will be visible.<br />
concatenates a skew onto the current<br />
transformation.<br />
