Hi Steve:
When you say only the front shows up.. Im not sure what that means.. Can you possibly post a snapshow of that project screen? The 3d model should be flat backed, it only extrudes to the front, BUT, it is possible what your getting is a very low profile bas relief. If so, things are probably working normally.
The module is a bas relief generator, to do what it does it uses whats called the "Shadow ambiguity" of
a set of images. The Shadow ambiguity is what allows for bas reliefs like you see on greek building and such, a very low profile shape who's shadows make the object "look" like its much deeper or in some cases fully 3d.
The more shadow data in the images, the deeper and more fully 3d the result will actually be. This means the differences between the 4 images must be huge for a truly thick sculpture like the examples I show.
You need total darkness in the room for example, and the larger the monitor the better. You need the camera to be close to center of the monitor ( though if it isnt the result will simply be tilted up or down some..). Most important is total darkness, you want the only image to be from the light cast by the
monitor as it flashes its various quadrants to create the shadows.
The more similar the images, due to room lighting or whatever, the lower the profile down to the point
where it looks more like just a photo with some edges. This type of problem may look like a flat photo
if sent to the project screen? Could that be what your facing?
