migrate engine to forward+ #74

Open pollend opened 1 year ago

pollend commented 1 year ago

Deferred rendering is very memory intensive, with a reworked deferred renderer I think its easier to build a forward+ render to replace the deferred renderer currently in the engine.

Visibility Buffer: this seems like a good middle ground without ditching the entire deferred pipeline.

There is an early prototype Forward+ renderer in hpl2 I'm playing with.

after some careful review I think its more feasible to replace the current pipeline with a triangle visibility buffer. lets me keep a lot of the features of a deferred pipeline. more straightforward change to implement.
