int removepoint(int geohandle, int point_number)
int removepoint(int geohandle, int point_number, int and_prims)
geohandle
A handle to the geometry to write to. Currently the only valid value is 0
or geoself, which means the current geometry in a node. (This argument may be used in the future to allow writing to other geometries.)
point_number
If this is 1
, the function has no effect.
and_prims
If this is 1
, the function deletes any degenerate primitives that referred to the removed point (for example, closed polygons with fewer than 3 vertices or open polygons with fewer than 2 vertices).
If this is 0
, the function only deletes primitives that become invalid because of the removed point (for example, tetrahedra with fewer than 4 vertices, or volumes with zero vertices).
