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

EXAMPLES

% vsurf -i surface -norm normals -ang angles
