VB: is gluTessVertex wrongly defined??
Author
Visual Basic 6:
gluTessVertex(tessObj as Long, coords as GLdouble, data as Any)
Well... How can I pass a 3D point coordinates to gluTessVertex??
I get an "Argument type error" when passing any kind of array, of course. I get no drawing too when passing the first element to this function...
Is this function wrongly defined in VB? Am I wrong?

I can''t find info about OpenGL + VB!!
I tried Google, Wisenut, Altavista, etc... They have indexed no sites with these words...

A quick look at the glu1.3 spec at www.opengl.org gave the following definition:
void gluTessVertex( GLUtesselator *tess, GLdouble coords[3], void *vertex data );
coords give the coordinates of the vertex in 3-space. For useful results, all vertices should lie in some plane, since the vertices are projected onto a plane before tessellation. vertex data is a pointer to a user-defined vertex structure, which typically contains other vertex information such as color, texture coordinates, normal, etc. It is used to refer to the vertex during rendering.

That''s right... but look at the VB definition of gluTessVertex:
gluTessVertex(tessObj as Long, coords as GLdouble , data as Any)
coords is a just a Double value, not an array of three Double values...
