subroutine cxGeoColorAdd(n,color,per) integer n real color(3, n) integer per
n
The number of RGB triples passed in.
color
An array of RGB color values in [0..1].
per
A flag indicating how colors are to be applied.
This function adds colors to the current point set, line set, polygon set, triangle mesh set, sphere set, cylinder set, or grid. The current object is the primitive or pushed transform most recently defined, or it may be explicitly set with cxGeoFocus(3E).

Colors may be applied in different ways, depending on the setting of the per flag:

CX_GEO_PER_OBJECT
a single attribute is used over the entire object
CX_GEO_PER_FACE
a different attribute is applied on each face (valid for polygons, triangles, and grids)
CX_GEO_PER_VERTEX
a different attribute is applied per vertex (valid for points, lines, polygons, triangles, and grids)
CX_GEO_PER_VERTEX_INDEXED
a different attribute is applied on each reference to a vertex (valid for lines, polygons, and triangles)

Colors are interpreted as RGB triples with each component in the range [0..1].
