VRMesh is a new style of sketch-based free-form 3D polygonal parametric modeling software. It creates an object directly from a sketched curve, represents the object with a two-manifold triangle mesh, and also provides a bundle of mesh editing tools to modify objects indirectly or directly on the triangle mesh.
VRMesh is an effective design tool for rapid prototyping, industrial design, architecture, entertainment, scientific simulation, and assembly planning -- any design field that deals with the articulation of 3D spaces and forms.
Just sketching a curve, you will get a 3D model. Check it out here:
