Function Additions/Modifications
In the SOP/POP contexts, there is a new function
computenormal
which can be used to control the generation of the normal attribute from within the VEX function.
There are new functions for querying metaball geometry from disk files. The
metastart
,
metanext
and
metaimport
functions can be used to evaluate metaball attributes per-metaball. This provides a more general interface to evaluating metaball fields. These functions are available in all VEX contexts.
There is a new function,

which returns the bounding box of a geometry file on disk.
