Function<br />
Description<br />
RiCoordSysTransform (space) sets the current transformation to be the one previously<br />
named with RiCoordinateSystem.<br />
RiCropWindow (xmin, xmax,<br />
ymin, ymax)<br />
RiDepthOfField (fstop,<br />
focallength, focaldistance)<br />
RiDetail (bound)<br />
RiDetailRange (minvisible,<br />
lowertransition, uppertransition,<br />
maxvisible)<br />
RiDisplacement (name,<br />
parameterlist)<br />
RiDisplay (name, type, mode,<br />
parameterlist)<br />
RiExposure (gain, gamma)<br />
RiExterior (name, parameterlist)<br />
RiFormat (xresolution,<br />
yresolution, pixelaspectratio)<br />
RiFrameAspectRatio<br />
(frameaspectratio)<br />
RiFrameBegin (frame)<br />
RiFrameEnd ()<br />
RiGeometricApproximation<br />
(type, value)<br />
RiHider (type, parameterlist)<br />
RiIdentity ()<br />
RiIlluminate (light, onoff)<br />
RiImager (name, parameterlist)<br />
RiInterior (name, parameterlist)<br />
RiLightSource (name,<br />
parameterlist)<br />
RiMatte (onoff)<br />
renders only a subrectangle of the image.<br />
focaldistance sets the distance along the direction<br />
of view at which objects will be in focus.<br />
sets the current detail to the area of the bounding<br />
box bound in the raster coordinate system.<br />
sets the current detail range.<br />
sets the current displacement shader to the named<br />
shader.<br />
chooses a display by name and sets the type of output<br />
being generated.<br />
controls the sensitivity and non-linearity of the exposure<br />
process.<br />
sets the current exterior volume shader.<br />
sets the horizontal (xresolution) and vertical (yresolution)<br />
resolution (in pixels) of the image to be<br />
rendered.<br />
frameaspectratio is the ratio of the width to the<br />
height of the desired image.<br />
marks the beginning and end of a single frame of<br />
an animated sequence.<br />
<strong>The</strong> predefined geometric approximation is<br />
”flatness”.<br />
<strong>The</strong> standard types are ”hidden”, ”paint”, and ”null”.<br />
sets the current transformation to the identity.<br />
If onoff is RI TRUE and the light source referred to<br />
by the RtLightHandle is not currently in the current<br />
light source list, add it to the list.<br />
selects an imager function programmed in the<br />
Shading Language.<br />
sets the current interior volume shader.<br />
creates a non-area light, turns it on, and adds it to<br />
the current light source list.<br />
indicates whether subsequent primitives are matte<br />
objects.<br />
