error

public void error(int errnum)

Specified by:

combine

public void combine(double[] coords,
                    java.lang.Object[] data,
                    float[] weight,
                    java.lang.Object[] outData)

Implementation of the GLU_TESS_COMBINE callback.

Specified by:

combine in interface javax.media.opengl.glu.GLUtessellatorCallback

Overrides:

combine in class javax.media.opengl.glu.GLUtessellatorCallbackAdapter

Parameters:

coords - is the 3-vector of the new vertex

data - is the vertex data to be combined, up to four elements. This is useful when mixing colors together or any other user data that was passed in to gluTessVertex.

weight - is an array of weights, one for each element of "data" that should be linearly combined for new values.

outData - is the set of new values of "data" after being put back together based on the weights. it's passed back as a single element Object[] array because that's the closest that Java gets to a pointer.
