VCHULLVisionX V4
NAME
vchull − calculates the 3D convex hull
SYNOPSISvchull if=<infile> of=<outfile>
DESCRIPTIONvchull
vchull computes a 3D convex hull. It takes in an image file and obtains its outer layer (vmorph -e, xor). Then it calls vpixloc to compute the locations of its non-zero pixels. The locations are used by qhull to compute the convex hull. The output of qhull is converted to a V3D file by using vofftov3d and the V3D file is used to render the actual convex hull output image (of) using vring and varend.
CONSTRAINTInput file if is a VisionX image. Output file is the convex hull image.
