Temporally Dense Ray Tracing by Pontus Andersson, Jim Nilsson, Marco Salvi, Josef Spjut, and Tomas Akenine-Möller.
Hang on, measuring monitor refresh rate...
Here we show the results of applying TAA in a reflection without reflecting the motion vectors (left), compared to using reflected motion vectors (right),
which is what we use in our work. A few things to note:
- We limit this sequence to 30 FPS in order to make the differences easier to notice.
In the reflection, you can see that the checkered pattern on the left is more blurred out than that on the right.
You can stop the animation by pressing "0 FPS" to compare the per-frame quality.
- During animation, the left reflection appears to stutter. This is due to the primary ray jittering and the poor temporal accumulation following from incorrect motion vectors.
