property DataSetMapper.resolve: str[source]#

Set or return the global flag to avoid z-buffer resolution.

A global flag that controls whether the coincident topology (e.g., a line on top of a polygon) is shifted to avoid z-buffer resolution (and hence rendering problems).

If not off, there are two methods to choose from. polygon_offset uses graphics systems calls to shift polygons, lines, and points from each other. shift_zbuffer is a legacy method that is used to remap the z-buffer to distinguish vertices, lines, and polygons, but does not always produce acceptable results. You should only use the polygon_offset method (or none) at this point.


Global flag to avoid z-buffer resolution. Must be either off, polygon_offset or shift_zbuffer.
