How is Ambient Occlusion calculated in "Deep Screen Space"?
The paper (http://resources.mpi-inf.mpg.de/DeepScreenSpace/) just says that
"The ambient occlusion contribution of a surfel to a pixel [..] as
well as the influence radius [..] are computed ...

Why is Forward Rendering/Shading named this way?
Forward rendering is the 'classic' approach to the rendering pipeline.
Nowadays it is mostly replaced by a more flexible, deferred rendering approach.
I did some research and had trouble finding ...

Is it possible that a superior, undiscovered 3D rendering method exists?
As far as I know, the only options we have for true 3D rendering are polygonal rendering, ray-marching and raytracing/casting.
Why is that? Surely there must be other ways? Is there some paper ...

What is it that really prevents photo-realistic, real-time, digital 3D simulations?
Ever since I was a small child, seeing the amazing 3D visuals that developed in the 1980s and 1990s, I was certain that photo-realism was "just around the corner". In the year 2020, I certainly ...
