Hi Jesse
Thanks for the reply. However, I did not use negative values for minimal distance, but nevertheless, all visible objects were shifted to the left in the left eye image.
I used the parameters shown below for the right eye image, and then calculated the left eye image using 0.5, 0.25 and 0.3 for 'Screen distance', 'Image width' & 'Minimal distance'.
The results (side by side, left eye image on the right for stereoscopic cross-eye viewing) are visible in the image shown. The central part of the image - the cube-like structure - is shifted from the center of the image (right eye image) to the left (in the left eye image).
This problem most probably occurs because M3D does not know where the (visible) objects really are, and in this case, assumes that the object the two cameras have to fix upon is closer than it actually is: the program tries to center the viewing axis of the left eye camera on a (non-existing) object that is nearby, and thus for any ('real') object positioned at a greater distance, the line of sight passes it on its right side (as seen from the viewer), resulting in the object to be shifted from the center of the image to the left. So, I guess, to avoid this, it will be necessary for the program to know on which (actually existing) object the camera angle has to be fixed. Maybe this could be implemented in a similar way as the DOF point & click procedure to set the focus of the camera on the surface of an object ...
(James Cameron said in an interview that he generally slaved the fixation point for the cameras to the focus point when shooting the movie 'Avatar').
In general, I would like to have some more information about how the Mandelbulb 3d camera setup really works with respect to terms like 'field of view' (FOV) and 'rectilinear lens', and if camera perspective can be set to '0' (i.e. no perspective at all; lines of view are all parallel) etc.
For Apophysis 3D, there is a tutorial with explanations and examples that are very helpful in this regard.

Maybe it is possible to have a similar tutorial or something that allows for making cross-references to this topic ...
