v3pmask − mask a 3D polygon file using a 3D image

v3pmask [if=<inputfile>] [ig=<inputfile2>] [of=<outputfile>] [-p] [-v]

V3pmask removes polygons from a 3D polygon file based on a 3D (typically binary) mask image. If a vertex appears at coordinates that have a non-zero in the mask image, the polygon containing that vertex is removed. This operation is useful in selectively trimming a polygon file prior to size, shape, and surface analysis. Note, the polygon vertex coordinates are rounded to the nearest integers to map them into the 3D image space for masking.

if=<output file>

specifies a VisionX 3D polygon (VX_V3D) input file.

of=<output file>

specifies a VisionX 3D polygon output file.

-p

inhibits packing of the output.

-v

verbose operation. Prints some runtime information.
