How do I project a 3-D traingle at a square grid onto a scrunched-up paper like surface?
To do this without holography is likely impossible(not sure though)
However, there is another way!
If you wish to experiment with 3-D projection on irregular sufaces this can be done, extremely well, using ray tracing programs such as Caligari TrueSpace.
It's not clear what you're looking for. You need to give more detail. Do you want to end up with a 3-D image like a hologram (expensive) or do you just want a 2-D projection of a 3-D image (camera lucida?)? What is the geometry of your source (What/where is it)? What exactly is the "scrunched-up paper like surface" intended to be? Maybe if you clarify these things someone can answer.
