I found interesting free software to make a 3ds-Models out of stereoscopic pictures. You can even use two or more than two similar pictures like they are made by shooting a lenicular photo and to calculate automatically a 3-D model out of this. That calculated 3-d model can be used for creating 3-D environments or for creating pictures between those two original pictures of a stereoscopic shoot, those pictures between are required, if You like to print Your own lenicular photo.
The software is free using java (a little slow, but it works):
