VPCLIPVisionX V4
NAME
vpclip − clip a region of a VisionX polygon file
SYNOPSISvpclip [if=<input_file>] [of=<output_file>] [xl=<x>] [xh=<x>] [yl=<y>] [yh=<y>] [zl=<z>] [zh=<z>] [-b] [-z] [-t] [-v]
DESCRIPTIONvpclip extracts a contiguous three-dimensional region of a VisionX 3D file that contains 3-D vectors polygons. A modified bounding box is specified by the parameters and all the data elements are clipped to fit into the modified bounding box. Three-D vectors other then triangles are deleted if any portion of them falls outside the new bounding box; triangle polygons are cut if they intersect the bounding box and may be split into two so that there is a clean edge to the cutting plane. If the -t flag is specified then triangles are considered as other vectors and are simply deleted if any vertex falls outside the cutting plane.
OPTIONS|
if= |
Input VisionX file |
|||
|
of= |
Output VisionX file |
xl=<value> Specify the
low x coordinate of the modified bounding box.
xh=<value> Specify the high x coordinate of the
modified bounding box.
yl=<value> Specify the low y coordinate of the
modified bounding box.
yh=<value> Specify the high y coordinate of the
modified bounding box.
zl=<value> Specify the low z coordinate of the
modified bounding box.
zh=<value> Specify the high z coordinate of the
modified bounding box.
|
-b |
The -b clip the data but maintain the original bounding box. | ||
|
-z |
Translate the bounding box and the data so that the the lowest coordinate of the bounding box is 0,0,0 | ||
|
-t |
The -t option specifies an operation in which the polygons not inside the bounding box are deleted instead of trimmed. | ||
|
-v |
The -v option specifies a verbose mode of operation in which some information is printed. |
