I found your roto when searching for papervision results. I am currently working on my diploma trying to make a dish configurator. As I would like to makte the interface with flash, I am now trying to get into papervision but it is very difficult. Would it be too much if I asked you for the source-code of your roto? As papervision has quite bad documentation and I am not really into programming I feel a bit lost. If you like you can visit my Blog where I have posted some images frm processing and a pdf of the current state of the interface. http://www.goldprodukt.de/individualized/ Thanks for your help!

A bezier wouldn't be any problem at all but is different from what you see here. Anyways this is the curve class I use to generate image levels so it goes from 0x00..0xff on x-axis and same for y-axis. The funcion which goes from 0 to 1 is like ( ( curve[ t * 0xff ] - 0x80 ) / 0x80 ) * scale which is not such a good idea. I just wanted to be able to transform the mesh actually (which is quick&dirty) :) It is not a bezier curve but cubic interpolaton over some given points.

The bezier curve is really weird. Are you sure the code of it doesn't have a bug somewhere? Apart from that, really nice example! They used to call that to revolution a shape.
