Cardioid (creation animation)

3D Model

In geometry, a cardioid is a plane curve traced by a point on the perimeter of a circle that is rolling without slipping around a fixed circle of the same radius. I made this back in May, and now I decided to post it. That day I learned about the dynamic paint feature in Blender. Unfortunately, it seems that Sketchfab does not support dynamic paint, so here I immediately added a pre-drawn trajectory to the plane along which the drawing cylinder moves. The cache for rendering the cardioid in real time, referenced by the plane during rendering, is on my computer and my Sketchfab plan does not allow me to attach additional files here.
