Interface TesselatorVisitor

All Known Implementing Classes:

VertexArrayList

public interface TesselatorVisitor

A TesselatorVisitor abstracts the sending of a list of OpenGL geometry to an OpenGL engine. For old OpenGL implementations, only glBegin and glEnd functions can be used, whereas on more recent versions, Vertex Arrays are much faster since they avoid a function call overhead at each vertex. This is even more true from gl4java that needs to perform a JNI function, more expensive than a mere C function call. TesselatorVisitor objects are meant to be used by Tesselator objects, and for other purposes as well.

Method Summary

void	addVertex(double x, double y)
void	begin(int mode)
void	combine(double[] coords, double[] vertex_data, float[] weight, double[] dataOut)
void	end()
void	error(int errorCode)
