Show HN: Rotation via Double Reflection https://ift.tt/lunWz4I

Show HN: Rotation via Double Reflection While studying Geometric Algebra I have built some interactive visualization to demonstrate how geometric transformations (rotation, scaling, translation) can be constructed by just composing reflections. Accepting reflection as the most elementary geometric operation was an eye opening moment for me. I think some of you might enjoy the interactive visuals. https://ift.tt/GMdEoQl August 21, 2026 at 07:18AM
