Polygonal modeling
Polygonal modeling is an approach for modeling objects by representing or approximating their surfaces using polygons. Polygonal modeling is well suited to scanline rendering and is therefore the method of choice for real-time computer graphics. Alternate methods of representing 3D objects include NURBS surfaces, subdivision surfaces, and equation-based representations used in ray tracers.
PTSource PolyDraw
PTSource PolyDraw is a free 3D polygonal modeller for Windows x86 and x64, for creating or modifying 3D objects using a mesh of 3D points and parametric NURBS Curves .Exports and imports to over 40 formats including WebVR and 3D Printing.

Features
- Fast rendering (ASM 3d engine)
- WebVR A-Frame template generation.
- Exports to WebVR (ready for interactive web viewing), STL for 3D printing, JSON for ThreeJS and more, see supported formats bellow.
- Allows you to create objects from Sweeps & Extrusions, basic shapes (cubes, cylinders, etc), meshes (vertices & triangles) and parametric NURBS Curves.
- Pre-made example models inside the program folder under Objects.
- Has lists to allow you to view & edit all the data by keyboard.
