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.
