PROGRAM NAME
vsurf - Compute Surface Parameters (Normals and Angles) (K1)
DESCRIPTION
vsurf
will take a surface image and produce two output images: one with
the normals for each point on the surface and one with the angle
between the surface normal and the normal to the
zero plane of the image.
The angle output image is in degrees.
REQUIRED ARGUMENTS
- -i
-
type: infile
desc: input image
- -norm
-
type: outfile
desc: output normals image
- -ang
-
type: outfile
desc: output angles image
OPTIONAL ARGUMENTS
none
