|Session Name:||Towards Cinematic Quality, Antialiasing in 'Quantum Break'|
|Company Name(s):||Remedy Entertainment|
|Track / Format:||Programming|
|Overview:||'Quantum Break' was shipped with a light pre-pass rendering engine, where geometry buffers are drawn with 4xMSAA. In this presentation Tatu will go over how to first reduce geometry data using clustering, then calculate lighting on smaller amount of samples, and lastly how to scale back to MSAA image. In addition, this talk will go over Remedy Entertainment's approach to temporal anti-aliasing, where previous four frames are combined for upscaled final image and how this leads us to using sequential noise patterns in sampling volumetric lighting and reflections.|
