Rendering
- rpict is the renderer, producing a Radiance image on its standard output.
- rvu is an interactive renderer, opening an X11 window to show the render in progress, and allowing the view to be altered.
- rtrace is a tool for tracing specific rays into a scene. It reads the parameters for these rays on its standard input and returns the light value on standard output. rtrace is used by other tools, and can even be used to render images on its own by using the vwray program to generate view rays to be piped to it.
- dayfact is an interactive script to compute luminance values and daylight factors on a grid.
- findglare takes an image or scene and finds bright sources that would cause discomforting glare in human eyes.
- mkillum takes a surface (e.g. a window or lamp shade) and computes the lighting contribution going through it. This data is then used by the illum material modifier to make lighting from these secondary sources more accurate and efficient to compute.

Famous quotes containing the word rendering:
“But of all the views of this law [universal education] none is more important, none more legitimate, than that of rendering the people the safe, as they are the ultimate, guardians of their own liberty.”
—Thomas Jefferson (1743–1826)
“The problem is that we attempt to solve the simplest questions cleverly, thereby rendering them unusually complex. One should seek the simple solution.”
—Anton Pavlovich Chekhov (1860–1904)
“Woe to the makers of literal translations, who by rendering every word weaken the meaning! It is indeed by so doing that we can say the letter kills and the spirit gives life.”
—Voltaire [François Marie Arouet] (1694–1778)
