How to draw Air
-
I am trying to illustrate hot air flow as shown by the translucent orange color. The second picture shows something similar - but not quite - of what I am trying to achieve. Any ideas on how to do this would be appreciated.

You could use some semi-transparent png image like (made on another occasion) in this model: http://sketchup.google.com/3dwarehouse/details?mid=ed6d520e6fb1c534c045bcbc26359030&prevstart=0

You may like to have a go with HTML5 canvas. I have been using the KineticJS library which makes things much easier. You could create the smoke effects using the shapes, shaders and filters there and make a png image overlay with its dataToUrl method. You can do it manually or use JavaScript to set up criteria to generate it (if varying conditions were important).

Gai....Very nice! Going to try that.
Chris....Never heard of that before. Will check it out. Thanks to both of you.
