NAME

DoPointList − Create a point list primitive object

SYNOPSIS

C:

DtObject DoPointList(colormodel, vertextype, pointcount, vertices)
DtColorModel colormodel;
DtVertexType vertextype;
DtInt pointcount;
DtReal vertices[];

Fortran:

INTEGER∗4 DOPNTL(COLMOD, VTXTYP, PNTCNT, VTXS)
INTEGER∗4 COLMOD
INTEGER∗4 VTXTYP
INTEGER∗4 PNTCNT
REAL∗8 VTXS(∗,∗)

DESCRIPTION

DoPointList creates a primitive object that defines a list of independent points.  The parameter colormodel specifies the color model to be used when defining vertex colors (if any).  The parameter vertextype specifies the exact nature of the vertex: whether the vertex contains color and/or normal information for shading purposes.  See the appendix on vertex types for more information on this parameter.  The parameter pointcount contains the number of points in the list.  The parameter vertices is an array containing data for pointcount vertices. 

If vertex normals are not provided, backface culling has no effect for points because they have no surface on which to define a geometric normal.
