ObjGen [beta]

ObjGen is the online OBJ file generator you didn't know you've been waiting for.

No more sleepless nights in front of [insert dysfunctional 3D software here]. Simply input the dimensions of your LED stage below, and ObjGen will do the tedious and time consuming work for you. The resulting .obj file will be generated using meters as the base unit where positive X is right (stage left), positive Z is forward (upstage) and positive Y is up. The UV coordinates are normalized between [0,0] (bottom left) and [1,1] (top right), so it's plug and play into applications such as d3 or Blender. Comments, questions, or suggestions?
