gluTessVertex function
The gluTessVertex function specifies a vertex on a polygon.
Syntax
void WINAPI gluTessVertex(
GLUtesselator *tess,
GLdouble coords[3],
void *data
);
Parameters
-
tess
-
The tessellation object (created with gluNewTess).
-
coords
-
The location of the vertex.
-
data
-
An pointer passed back to the program with the vertex callback (as specified by gluTessCallback).
Return value
This function does not return a value.
Remarks
The gluTessVertex function describes a vertex on a polygon that the user is defining. Successive gluTessVertex calls describe a closed contour. For example, to describe a quadrilateral, call gluTessVertex four times. You can only call gluTessVertex between gluTessBeginContour and gluTessEndContour.
The data parameter normally points to a structure containing the vertex location, as well as other per-vertex attributes such as color and normal. This pointer is passed back to the program through the GLU_VERTEX callback after tessellation (see gluTessCallback).
