Implies frequency domain computations.
Grid size set to cover approximately one bucket when ShadingRate
=1.
See Advanced RenderMan: Creating CGI for Motion Pictures, p.151, for a complete discussion about eye splits.
Was Option "render" "max_raylevel"
in versions prior to 1.0 .
Approximate, since it is computed as follow : (number of buckets rendered) / total number of buckets.
Was Attribute "visibility" "integer reflection"
in versions prior to 1.0 .
Was Attribute "visibility" "integer shadow"
in versions prior to 1.0 .
This is the equivalent of the deprecated Attribute "render" "int truedisplacment"
.
Useful for "ambient occlusion" renderings.
Other subdivision schemes (such as Loop and Butterfly) will be rendered as polygonal meshes.
Deriv()
computes the following expression: Du(num)/Du(denum) + Dv(num)/Dv(denum)
When converting to and from XYZ color space, 3Delight considers that RGB tristimulus values conform to Rec. 709 (with a white point of D65 ).
Was visibility()
in versions prior to 1.0.
Ray directions are sampled from a cosine distribution. Also applies to occlusion()
.
See `man regex' for details (man

Not avilable on Windows platforms.
