NAME
cxGeoGridDefine
- create a grid geometry object
C SPECIFICATION
#include <cx/Geometry.h>
cxGeo cxGeoGridDefine(
int nu,
int nv,
float *point )
FORTRAN SPECIFICATION
integer function cxGeoGridDefine(nu,nv,point)
integer nu
integer nv
real point(3, nu, nv)
PARAMETERS
-
nu
-
Number of grid samples in the u direction.
-
nv
-
Number of grid samples in the v direction.
-
point
-
An array of XYZ triples for grid sample coordinates.
DESCRIPTION
This function creates a grid, a two-dimensional surface regularly sampled in
parameter space. There should be nu*nv grid sample
coordinates in the
array point with the nu index varying fastest.
The return value is a tag for this object that may be used to reference
it at a later time with cxGeoFocus(3E).
Valid attributes are colors, normals, and transparencies. Attribute
distribution may be CX_GEO_PER_OBJECT, CX_GEO_PER_FACE, CX_GEO_PER_VERTEX,
or CX_GEO_PER_VERTEX_INDEXED.
