Constructor Detail

TessCallbackAdapter

public TessCallbackAdapter(CombineContext cc)

Creates a new TessCallbackAdapter with a CombineContext that receives GLU tessellator callbacks sent to this instance.

Parameters:

cc - the CombineContext that receives forwarded GLU tessellator callbacks.

Method Detail

begin

public void begin(int type)

Calls CombineContext.tessBegin with the specified type.

Specified by:

begin in interface GLUtessellatorCallback

Overrides:

begin in class GLUtessellatorCallbackAdapter

Parameters:

type - the GL primitive type.

combine

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

Calls CombineContext.tessCombine with the specified arguments.

Specified by:

combine in interface GLUtessellatorCallback

Overrides:

combine in class GLUtessellatorCallbackAdapter

Parameters:

coords - A three element array containing the x, y and z coordinates of the new vertex.

vertexData - The caller specified vertex data of the original vertices.

weight - The coefficients of the linear combination. These weights sum to 1.

outData - A one element array that must contain the caller specified data associated with the new vertex after this method returns.

end

public void end()

Calls CombineContext.tessEnd.

Specified by:

end in interface GLUtessellatorCallback

Overrides:

end in class GLUtessellatorCallbackAdapter

error

public void error(int errno)

Calls CombineContext.tessError with the specified errno.

Specified by:

error in interface GLUtessellatorCallback

Overrides:

error in class GLUtessellatorCallbackAdapter

Parameters:

errno - a GLU enumeration indicating the error.

vertex

public void vertex(java.lang.Object vertexData)

Calls CombineContext.tessVertex with the specified vertexData.

Specified by:

vertex in interface GLUtessellatorCallback

Overrides:

vertex in class GLUtessellatorCallbackAdapter

Parameters:

vertexData - the caller specified vertex data.
