WebGL FBO Particle System
See your 3D objects as a cloud of particles in this new WebGL experience called Point Cloud Sandbox. Just specify the number of particles (between 10,000 to 2 million), upload any OBJ, PLY, or JSON 3D files and voila! Your solid 3D object is now composed of particles you can manipulate or play with.
The creator of this project wanted to port his experiences in creating particle systems to a web page through WebGL and Javascript. He actually had to write a new FBO oriented system from scratch, since he was not satisfied with the other approaches that were then available.
The final product is this awesome sandbox. You can adjust a number of parameters, like tesselation, texture, mesh gravity, and lighting. A brush lets you twist, stretch, contort, or just warp the object any which way you want.
