Added a frequency of rendering output to the virtual camera demo. I'm geting about 70-80 Hz on my little machine with Chrome and integrated graphics. It will be interesting to see the difference when I set up the other computer with a new graphics board. I should have made this first, so I could figure out what the hungry bits were as I added them in!
| Intel Integrated | AMD HD 7570 | |
| Chrome 32 | 70-80 Hz | 60 Hz |
| Firefox 32 | 60 Hz | ? |
| Chrome 64 | n/a | 60 Hz |
| Firefox 64 | n/a | 60 Hz |
Edit: 12 July 2012: Chrome has a built in frame-limiter (vsynch) to prevent tearing. You can turn this off in about:flags to get it to run at higher rates.
Had a look at this demo which uses morph targets. Works pretty well. There's a read-later article on speech synthesis with a talking head in Italian with WebGL here.
