Lighting
Ag
Rationale
We require the outputs of Several frames for our effects.
We want to handle multiple light sources.
Our solution: deferred lighting.

Glow
Fundamental effect
Ensuring high-quality glow is a priority
Technique: Render glowing parts of frame to small target
Blur glow target, scale and add to frame

Resolution artifacts
Problem: Low resolution might cause moving discontinuities inglowing regions
Solution: Add previous frames to glow (effectively a slightmotion blur)
Doesn’t solve artifacts completely, but makes effect a lotsmoother
The blurring of the glow looks nice as you move :)

Motion Blur Calculation
After a frame is rendered, the previous frame is multiplied bya scale factor and added to it
If speed is below an amount bmin, the scale factor should be 0.
If speed is above an amount bmax , the scale factor should notincrease anymore.
The scale factor f is computed from current speed s asfollows:
t =s − bmin
bmax − bmin
f = kbt2(3 − 2t)
