5.2 Ray Tracing

The trace() function of the shading language is fully implemented in 3Delight, with the exception that moving object will not be motion blurred.

3Delight also implements other functions related to ray-tracing, they are listed below and described in more detail in section 4.5 Shading Language.

color trace ( point from; vector dir [; output float dist] )
float trace ( point from; vector dir )
color transmission ( point p1, p2 )
float isshadowray()
float raylevel()

Make sure that visibility attributes are properly set: by default, 3Delight marks objects as being visible to camera only.
