34   DESCRIPTION
35       The  rtcInterpolateN  is similar to rtcInterpolate, but performs N many
36       interpolations at once.  It additionally gets an array of  u/v  coordi‐
37       nates  and a valid mask (valid parameter) that specifies which of these
38       coordinates are valid.  The valid mask points to N integers, and a val‐
39       ue of -1 denotes valid and 0 invalid.  If the valid pointer is NULL all
40       elements are considers valid.  The destination  arrays  are  filled  in
41       structure of array (SOA) layout.  The value N must be divisible by 4.
42
43       To  use  rtcInterpolateN  for  a geometry, all changes to that geometry
44       must be properly committed using rtcCommitGeometry.

46   EXIT STATUS
47       For performance reasons this function does not  do  any  error  checks,
48       thus will not set any error flags on failure.
