NAME
cxGeoTextureCoordinate2Define
- define 2D texture coordinates
C SPECIFICATION
#include <cx/Geometry.h>
void cxGeoTextureCoordinate2Define(
int n,
float *point)
FORTRAN SPECIFICATION
subroutine cxGeoTextureCoordinate2Define(n,point)
real point(2,n)
PARAMETERS
-
n
-
Number of points.
-
point
-
An array of 2D coordinates which defines the mapping of textures
for vertex-based shapes.
DESCRIPTION
This function defines a set of texture coordinates which are used in the
mapping of texture onto the current point set, line set, polygon set,
triangle mesh set, sphere set, cylinder set, or grid. The current
geometry object
is the primitive most recently
defined, or it may be explicitly set with cxGeoFocus(3E).
Texture coordinates range from 0 to 1 across the shape. The horizontal (S)
coordinate is specified first, followed by the vertical (T) coordinate. The
texture coordinates are used by the cxGeoTextureAdd(3E) routine, which
adds the texture to the current object.
