Rendering Omni-directional stereo images using accelerad rpict

[qorba...@gmail.com]

Hey Nathaniel! I hope you are well. 

I was wondering if it is feasible to render the same equirectangular projection (Omni-directional stereo) that is available in AcceleradRT. I actually tried the parameter -vtc (for cylindrical projection) for rendering, but it was not the projection that I needed.

I need something like this render:

But using -vtc I get something like this:

Is there a specific parameter defined for this type of view in Accelerad rpict?

Thank you in advance.

Best regards.

AcceleradRT's omni-directional stereo projection is available through accelerad_rpict using the -vto argument. Note that omni-directional stereo is not quite the same as equirectangular projection because it involves a slight distortion of the ray origin point to provide the correct image for each eye.

Oh! I see. Thank you very much for your response!

So just to make sure, there is no parameter to render equirectangular images directly?

Best regards

Not directly. However, if you have a list of rays corresponding to the pixels of the desired image, you can use rtrace with the -ffc or -fac settings to produce any projection you want. This is what the vwrays program achieves, but vwrays is limited to the projections already available in rpict.
