Week 9: Changing Lights and Scenery

The task for this week was both bring in some more interesting geometry as well as to expose the lights to the GUI so they could be edited at run time. For the geometry, I used assets from Morgan McGuire's asset repository. Specifically, I used the living room and bedroom models because they both had interesting geometry for the lights to play off and create interesting shadows. This gave me images like this

With the new geometry squared away, I started exposing the lights to the gui. Falcor's light class has a built in method to simplify that, which exposes the parameters within the light, but doesn't provide any way of deleting it or adding a light to the scene. This is simpler with a ray traced scene than it would be with a more standard rendering method, if only because there are no light maps to recalculate---All lights are functionally dynamic lights. With that done, I experimented a bit with what I could make by messing with the lights I had.

The original scene

Changed the color of the light by the window to purple, moved it, and made it brighter. Made the hanging light brighter and bluer.

Deleted everything but the hanging light and found it pleasantly creepy.
