Here is an experiment where a fixed background (or texture) has been used behind an interact-able 3D model. The model was created using Blender. From Blender (or any other 3D software) export the model as FBX file.

The code formatting is getting horribly misaligned when pasted here. So here is the whole folder. Run the webgl_loader_fbx2.php. Though I have included files.js, but it not needed for this experiment.
