                 boolean calcNorm,
                 boolean clampXY)

begin

public void begin(int type)

addIndex

protected void addIndex(int tessIdx)

calcTriNormal

protected void calcTriNormal(int tessIdx0,
                             int tessIdx1,
                             int tessIdx2)

vertex

public void vertex(Object data)

Specified by:

vertex in interface PGL.TessellatorCallback

error

public void error(int errnum)

Specified by:

error in interface PGL.TessellatorCallback

combine

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

Implementation of the GLU_TESS_COMBINE callback.

Specified by:

combine in interface PGL.TessellatorCallback

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.
