3D cameras generally have two side-by-side lenses that the images from them are ether funneled onto one sensor or have dual sensors. (with my 2D camera I just take two different images)
There is no 'depth map' involved as the camera is simply capturing 'real life' and whatever already exists in the real world.
You can however play with the distance between the Left and Right images before and after capture and change the convergence point and as an effect of that change the depth.
Depending on the subject/target being photographed sometimes you may want the distance between the two lenses to be VERY large (4 or more inches) and other times you want them to be less than 1 inch. (many find a calibrated 'rail' that can be attached to a tripod helpful in this.) Sometimes you'll need 6 or more captures along the rail (from R-L or L-R) at set intervals for some printed products to be made.
I hope this helps.
