OpenSCAD Minkowski: Difference between revisions

Revision as of 22:22, 30 November 2020

Other languages:

Applies a Minkowski sum to selected shapes.

Add each element of subset A to each element of subset B to get Minkowski sum.

Sweep element A along all boundaries of element B. Resulting space which is occupied by both elements is Minkowski sum.

Example of Minkowski sum applied to cylinder and cube. Note: that the height of minkowski sum is height of cylinder plus height of cube.
