PMAP File
A PMAP (.pmap) file is a mental ray
photon-map on page 7894 file. This is a
binary file that the
mental ray renderer on page 6039 uses to generate the effects
of
caustics on page 6066 and global illumination on page 6072 . You specify a
name and location for the PMAP file on the Render Scene dialog > Indirect
Illumination panel > Caustics And Global Illumination rollout on page 6096 .
Point
A point in three-space, created when you use NURBS modeling to create a
Point Curve or Point Surface, or when you create an individual point
sub-object. Points that are part of a Point Curve or Point Surface are constrained
to lie on the curve or surface.
Points behave somewhat like vertices for
spline objects on page 542 , but their
behavior is not identical and they are a distinct object type.
Helper object
points
on page 2544 are also a distinct object type. You can't use spline vertices
or helper points as NURBS points (though you can convert a spline to a NURBS
curve).
