7.8 Radiance display driver

Use this display driver to write files compatible with Radiance. Floating point values are required for this display driver since it is intended as a HDRI output. The following parameter is recognised by this display driver:
"uniform string colorspace" ["rgb"]
Specifies in which color space to encode the values. The two possible values are "rgb" and "xyz" and the default is "rgb". Be careful when using "xyz" color space since it implies a RGB to XYZ conversion inside the display driver and RGB values are assumed to be linear, so setting Exposure to 1 1 is essential. Note that run-length encoding of Radiance files is not supported.

EXAMPLE

 
# Write out a radiance file, using XYZ colorspace.
Exposure 1 1
Quantize "rgb" 0 0 0 0  # use floating point data
Display "hdri.pic" "radiance" "rgb" "string colorspace" "xyz"
