This pull request aims to enhance our path tracer by introducing a direct light sampling. The current approach is to treat lights as ObjectHandlers with a specific flag. In this way we correctly calculate if an object is in direct line with a light when traversing the Scene.tree.
The work that needs to be done:
Surface Sampling: how to importance sampling for surface lights.
Choose and implement heuristic for weighting multiple lights: emitted power, surface/distance...
Update example of Cornell box with same renderer parameters.
