Quick noodle rigid body dynamics test using real-world relative scale. Details...: Pasta / spaghetti relative dimensions: 2.5mm dia., 250mm length, rigid bodies' mass (and centers of) calculated based on material densities, gravity: 9.8m/s. Physics are to scale, but unfortunately my movements (external forces) in the virtual world were too fast relative to the scale (and impatience due to simulation running slow ;) this was made obvious after rendering the frames and playing them back at real-time speed. Therefore movements and playback speed are not quite to scale. That's what tests are for... to learn from. The bizarre movements (using mouse): after dropping the fork in the glass I threw the glass, then threw the bowl, played with a noodle, then dragged the fork and threw it as well.

Fork, bowl and glass are compounded HACD convex decompositions. Noodles are capsule strings (no longer sticking with full radius as margin).

Step by step, we are slowly getting closer; one day we'll be able to easily simulate real-world physics using any arbitrary rigid body shapes... one day...
