OMR Model Render

[Lasse Deleuran]

I have added dat.GUI to set up the scene - see sample_physical.htm and call "scene.setUpGui()".

With this, I would like to revisit the state of the physical renderer:

1. Fix rendering issues This seems to be at a tolerable level. Right now the largest issues seem to come from line 2's partially overlapping line 5's.
   
2. Stud logos DONE using textures
   
3. Control buttons to set up camera, lights, etc. DONE using dat.GUI
   
4. Progress bar DONE using animated construction
   
5. Better support of transparency. WIP. From my prodding in the rendering communities, this seems to be very hard, and perhaps worthy of a research paper if I can create real-time realistic rendering of transparent elements
   
6. Support of illumination parts (such as glow-in-the-dark ghosts, etc.) MISSING
   
7. Distance-based blur for a more realistic rendering MISSING
   
8. Textures DONE: All 3 types of projection, as well as inline textures. Only issue is clamping where the standard clamping from three.js materials stretches textures to edges.
   
9. Geometry culling (such as removing studs that cannot be seen) WIP I am looking into the use of InstancedMesh for quicker rendering using less ressources.
   

I am currently looking into performance optimizations, such as #9 on the list. What is the general feeling for the readiness of this code base? Are there aspects you would like to see me improve further before proposing a release?
