Direct lighting vs global illumination CLI parameter #10

Closed Walther closed 2 years ago

Considering how significantly faster direct lighting can be, there should be a CLI option for switching between the two modes. This should be especially useful if/when pondering realtime use, preview renders for video, etc.

What should this option be called?

--mode global, --mode direct ?
--global=true, --global=false?
other?

Depends on https://github.com/Walther/clovers/issues/8

Could be difficult due to the Book 3 being quite hardcoded in the direct lighting chapter.

Closing for now. Global illumination is pretty and one of the main points of having an offline / non-realtime pathtracing engine.
