Hi y’all!
Demo Here!
Image Based Lighting (IBL) performs a color lookup from a surrounding cubemap based on an object’s normal vectors.
In this example, I dropped a reflective object into a cubemap in Three.js!

For an IBL primer, check out the 2003 Siggraph presentation.
I pulled the textures for the cubemap in the demo from Paul Debevec’s library of cube maps.
Mouse camera-tumble controls are handled by an orbital.js object.
