v3pfilt − 3D surface smoothing

v3pfilt [if=<inputfile>] [of=<outputfile>] [f=<value>] [r=<value>] [-p] [-v] [-a]

V3pfilt smooths a polygonal surface in a 3D polygon file. The algorithm modifies the position of each vertex as the weighted sum of neighboring vertices and itself. The f= parameter specifies the proportional weight given to the neighboring vertices. The default value is 0.9. In this case, the new location of a vertex depends 90% on the locations of neighboring vertices and 10% on its original location. In addition, the smoothing algorithm may be applied multiple times, using the r= parameter.

if=<output file>

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

of=<output file>

specifies a VisionX 3D polygon output file.

f=<value>

specifies the smoothing fraction parameter

(default = 0.9).

r=<value>

specifies the number of smoothing iterations (default = 1).

-p

inhibits packing of the output.

-v

verbose operation. Prints some runtime information.

-a

for compatability with older programs.
