A (target/base) = red, B (tool/brush) = blue Show how these operations affect the filled area. Color = true A OR B ( union ) A AND B ( intersection ) A XOR B ( symmetric difference / disjunctive union ) A NOT B ( difference )
Update_2017-10-08_2129: Deprecated lists (used by sort4) Cleaning up and simplifying the code. Using my new sort4-algorithm. Calculating 3 x 360 boolean operations per screen update. Showing off by adding a tick based variance on each screen-lines x-position. Last preparation before trying to create a project making 2D solid modeling using (chained) boolean operations.
