MeshLabJS
A javascript, client-side, mesh processing tool. Inspired by the well known MeshLab, MeshLabJS is built using, for all the mesh processing tasks, the c++ vcg library compiled into asm.js using emscripten and it relies on three.js for rendering. MeshLabJS is developed by the Visual Computing Lab of ISTI - CNR and by the students of the FGT course.
