leapmotion/sculpting ? reverse-engineered prompt

Build me a calm 3D sculpting app called Sculpting, formerly Freeform, where people can reach out and shape digital objects with natural hand style interactions. I want it to feel serene and creative, with different materials like glass, clay, and plastic, plus a range of sculpting tools and brush styles so users can refine their work in detail.

It should let me switch between rich visual environments, see the underlying wireframe when needed, and save my creations as .ply, .stl, and .obj files. Please make the experience polished and easy to use, with the focus on creating beautiful 3D models rather than complicated menus. Use the existing project structure if it helps, and look up current docs online if you need to confirm anything about the Leap Motion or the required libraries.
