|Session Name:||Forward Rendering Pipeline for Modern GPUs|
|Speaker(s):||Takahiro Harada, Jay McKee|
|Company Name(s):||AMD, AMD|
|Track / Format:||Programming|
This talk first presents Forward+, a forward rendering pipeline which allows for scenes with the same number of lights expected from a modern deferred renderer (on the order of thousands). Forward+ retains all the benefits of traditional forward rendering while eliminating all the downsides found with deferred rendering. After talking about the rendering pipeline, performance comparisons to deferred lighting will be shown to clarify the performance advantages. We then talk about another advantage of the pipeline: freedom to use arbitrarily complex materials and lighting models by showing a real-world example of how Forward+ is used in an AMD's Leo demo in which many lights and physically-based materials are used.
