Based on the experience I'm having now with WebGL, where everything is on a much lower level, I know that drawing lines as quads (option 1 and 2 in the above post) will always be slower than drawing using gl native line mode. In WebGL (following opengl) you can actually set the width of the lines that way, but Unity3d does not expose this functionality in the GL object. UPDATE: I was wrong about thick lines in WebGL, apparently for that you need to draw quads as well: http://sonargame.com/blog/2011/06/19/thick-lines-in-webgl/ @EricH vectrosity looks interesting!

Static lines are only the cost of having a mesh on the screen. With GL.LINES, you have to update all lines every frame, regardless of whether they're actually changing or not, or else they won't render. I optimized Vectrosity as much as I could manage, so even if you are updating all lines every frame, it's only about 2.5X slower than GL.LINES, but it's far more flexible. Among other things you have complete control over line width of every segment.

Is it a matter of UnityObject.js file? I am wondering how to properly embedd in full browser mode. Would be grateful for any comments.

But! Now when lines are thin everything is ok. But when lines are wider, there is perspective segmet distortion (based on camera pos). It'll be nice to have segments rotated towards camera. Like particles billboarding effect or native Line Renderer. LR problem is that LR align segments to camera but keeps segments connected. that provide unexpected twists and texture flips. Can you update the GR code? Please. Im not math guru but seems to me, you are. Thanks. Using GR method is almost perfect.

MrDoob's Harmony is awesome, but the 3d thingy has a nice feel to it too. If you could save a jpeg, it would be great. It has a nice potter's wheel touch to it and somwhat similar to Rhonda(rhondaforever.org) a bit.

I personally am glad that you've jumped into Unity3d land. I too have gone from being a flash dev (founder of flashkit.com even) into a unity game developer. Its just sometimes fun and exciting to try something new thats fun, and fast. Unity certainly has its quirks and issues ( lack of a click drag selection tool springs to mind) but the goodies it has are pretty sweet. Its just fun. And I wanted to say an extra special thanks for the sources to this demo :D Ive only just started playing with custom meshes and this has helped me out as well.... I reckon I could use this technique to make skids...... The GR version works well on the iphone too! I'm excited about whatever new goodies you come up with next. Wonderful!
