void CSG_FreeBooleanOperation

(

CSG_BooleanOperation *

operation

)

Free the memory associated with a boolean operation. NOTE any iterator descriptor describing the output will become invalid after this call and should be freed immediately.

void CSG_FreeVertexDescriptor

(

CSG_VertexIteratorDescriptor *

v_descriptor

)

Clean up functions. Free internal memory associated with CSG interface structures. You must call these functions on any structures created by the module, even if subsequent operations did not succeed.

CSG_BooleanOperation* CSG_NewBooleanFunction

(

void

)

Return a ptr to a CSG_BooleanOperation object allocated on the heap. The CSG module owns the memory associated with the returned ptr, use CSG_FreeBooleanOperation() to free this memory.

	)

If the a boolean operation was successful, you may access the results through the following functions.

CSG_OuputFaceDescriptor() returns a ptr to a CSG_FaceIteratorDesciptor allocated on the heap and owned by the CSG module. The iterator is positioned at the start of the internal face container. CSG_OutputVertexDescriptor() returns a ptr to a CSG_VertexIteratorDescriptor allocated on the heap and owned by the CSG module. The iterator is positioned at the start of the internal vertex container. There is no function to rewind an iterator but you may obtain more than one iterator at a time. Please use the function CSG_FreeFaceIterator() and CSG_FreeVertexIterator to free internal memory allocated for these iterators.

If the last operation was not successful, these functions return NULL.
