I'm trying to use tessellation, setting a combine callback with
(1) GL.gluTessCallback(tassellatore, GL.GLU_TESS_COMBINE, new GLUtessCombineProc(CB_COMBINE));
where the callback function is
Even if the parameters match with the ones of the related delegate, why the application in line (1) throws an exception like "Array size control parameter must be an integral type"?
To work around this issue, I tried to use the other callback type, GLUtessCombineProc2, with a callback function like
private void CB_COMBINE(RDouble coordinate, RPVoid datiVertici, RFloat pesi, RPVoid output)
I know "output" must contain data for the vertex obtained by the automatic combining, but *how* do I have to set data into it?
Thanks in advance :)
Did you have any success with this?
I'm also trying tessellation with CsGL in C# and am getting a System.NullReferenceException. It's doing this with the simple callbacks like GLU_TESS_BEGIN.
Here's the code:
//The callback function
void beginCallBack(uint type)
// Create a new tessellation object
tobj = new CsGL.OpenGL.GLUtesselator();
// Set callback function
GL.gluTessCallback(tobj, GL.GLU_TESS_BEGIN, new CsGL.OpenGL.GLUtessBeginProc(beginCallBack));
Here's where it gives the System.NullReferenceException.
Do you have an idea of where it's going wrong. Can you send me your code to just assign the callback?
