| func_void_from_Id_UndirectedEdgeTag_float_Vector3_float meshlib.mrmeshpy.DecimateSettings.adjustCollapse | ( | self | ) |
\\brief The user can provide this optional callback for adjusting error introduced by this edge collapse and the collapse position. \\details On input the callback gets the squared error and position computed by standard means, and callback can modify any of them. The larger the error, the later this edge will be collapsed. This callback can be called from many threads in parallel and must be thread-safe. This callback can be called many times for each edge before real collapsing, and it is important to make the same adjustment.
