A quick breakdown of lighting in the restir-meets-surfel branch of my renderer, where I revive some olde surfel experiments, and generously sprinkle ReSTIR on top.

General remarks

Please note that this is all based on work-in-progress experimental software, and represents a single snapshot in development history. Things will certainly change 😛

Due to how I'm capturing this, there's frame-to-frame variability, e.g. different rays being shot, TAA shimmering slightly. Some of the images come from a dedicated visualization pass, and are anti-aliased, and some show internal buffers which are not anti-aliased.

Animation Subsystem

AnimInstance is the runtime animation class that maintains runtime data & plays shit
	- This is the parent class of the animation blueprint
	- Get Bone Transforms from a specific time t:
		○ Sequence->GetAnimationPose(Output.Pose, Output.Curve, FAnimExtractContext(CurrentTime, Sequence->bEnableRootMotion));
		
	
UAnimationAsset is the classes that contain the actual data and also calculates bones & curves
	- UAnimSequence
