Firefox4 is rendering this demo the fastest

I was recently testing out Firefox4 beta. It has made huge strides in Javascript performance. It runs my old Normal Mapping demos much faster than in other browsers.
There is one exception: the Beth demo runs faster in Chrome 9 & 10.
Here are the stats running on my iMac 2.66 Ghz Intel Core 2 Duo. All numbers are in Frames Per Second (FPS). Higher values are better.
Demo | Firefox 3.6 | Chrome 10.0 | Firefox 4.0b11 |
Me | 37 | 50 | 98 |
Beth | 52 | 116 | 92 |
Cereal | 21 | 32 | 37 |
Cereal ( without glow effect ) | 30 | 46 | 54 |
Earth | 31 | 38 | 98 |
Head | 12 | 22 | 26 |
Statue | 7 | 5 | 13 |
Statue ( without glow effect ) | 11 | 7 | 18 |
Exported Texture Mapped Objects | 8 | 6 | 14 |
I added stats.js by @mrdoob to the demos so you can test it out yourselves. Please do leave a comment if you get dramatically different results.
Todo
- Write an article on rendering/calculation tricks I used for these demos.
- Release a Javascript library for generating and rendering them.
- Write a Tutorial on how to take photos and build normals maps from them. Include an intuitive explanation of the math behind it.
