Looks great! I’m not completely clear on what you were trying to accomplish - but it looks like you were able to do it. I’ve tried the steriogram, and it’s quite impressive.
How would you replicate this in LDView? It doesn’t have labelling on the slider for the stereogram setting. Is there another rendering program that would work better for this?

Hi Jeffrey,

I was just trying to render it in 3D such that it would look right if the viewer was a minifig standing on the ground plane. I’m not sure you could replicate it in LDView as it used non-orthogonal cameras. It is based on the include file from here (which also gives some of the theory) and I used POVray for the rendering.

LDView doesn’t support orthagonal cameras at all, actually. It supports camera angles as small as 0.1 degrees, which end up looking really close to orthagonal, but it doesn’t support orthagonal cameras. I’m assuming Jeffery’s original images were made in LDView.

LDView will let you move the camera to any arbitrary position and rotation when you’re in fly-through mode. In examine mode it puts contraints on the minimum distance from the model. (It also doesn’t let you do the equivalent of tilting your head left and right in examine mode, but you can rotate the model in various directions to reproduce the same final view.)

While it’s true that LDView’s stereo eye spacing slider doesn’t give you any idea of how far apart the two cameras are in model space, you can tweak it to get a fairly wide range of eye spacings.

For those people who can cross their eyes to see the 3d image, it looks pretty darn cool when the model is rotating ;-). (Yes, I’m one of those people; I doubt I would have added the feature otherwise.)
