A spline-based 3d mesh deformation tool called MegaShapes caught my eye on the Unity Asset store. I grabbed it and began testing.. It’s very cool. Simple API to access the spline points during runtime. Runs great on my ipad 3! Morphing a tube with around 10k tris runs at 60 fps. Even on my 4th gen iPod performance was acceptable. I’m pretty certain I’ll be using this instead of RageSpline in my current project for android and iOS tablets.
