Hi, as I haven't used processing in more than some
demo checking, please forgive me these questions.
I just need to know if Processing would be a good
solution for one of my ideas...

1) Is it possible to "collapse" the visual information
of an 3D object on the screen, for creating paint
strokes out of them or applying 2D image operations
over them?

2) Is it possible to copy a part of the screen to a buffer,
map this on a 3d object, distort it and put it back on
the visible part of the screen? (with Alpha channel)

3) Is it possible to work in big buffer and only
expose a part of it to the screen in a easy way?

4) I there a kind of morph construct to blend between
3D shapes?

Thanks a lot, RS

1) yes, but use P3D, because OPENGL currently has some issues with pixel grabbing. this is what the get() method is for, which will give you a PImage object from a subsection of the screen that can be manipulated.

2) see #1

3) eventually yes, right now it's not working particularly well. look at the notes about "PGraphics" (this is also relevant to question #1) in the "changes between releases" section of the faq.

4) has to be done by hand. we don't have a concept of a shape object currently as part of the api, so there's nothing really to facilitate that.
