I'll be sure and use some real markers next time. Thanks, Eric, that makes a lot of sense… it explains the switching around that happens in the beginning of the video.

I must have been relying on a bug which was fixed. *sigh* I will get around to fixing it at some point, but in the meantime you can check out the example linked to in my comment above this one, which is working.

Indeed this is no different than the built in Postcards in Space type of 3D that the flash player does automatically, except that I'm choosing to draw the vector shapes myself to avoid the bitmapification effect noted previously. Hope this makes sense. For most 'real' mesh-based 3D like you're doing you'd want to use projectVectors + drawTriangles. Hi

You can do it with projectVectors… http://wonderfl.net/code/36fd6419f66be343e9b0e8860d689f773f1cf7ac

See comments on previous post (now not working very well after change to new revision of flash player 10 fixed bugs I was somehow relying on) :

I am very interested by your example and I would like to know why you use localToGlobal instead of projectVectors. Thank you very much :D Hi,

I guess the new 3D API assumes some sort of familiarity with traditional 3D rendering processes - which I lack - so I'm not sure how to fit the pieces together sometimes.
