A 3D parametric surface grapher I made exclusively using data binding and artboard lists in Rive! Simply type in any formula you want into the X, Y, and Z converters in order to generate a custom 3D surface, rendered with depth effects and backface culling. The two surfaces displayed are a 5-fold torus knot and a logarithmic shell. You can try it here at: https://rive.app/s/UKiZWKvIsk2qdbADmyYptg/?runtime=rive-renderer
