Perspective axonometric isometry, stereo parallax experience ?

[sonno]

Hi,

I'm creating animations on a 3D model in MetaShape. I want the rendering to be as close as possible to what we see with the naked eye. I'd like to check with you that the perspective calculation value of the default view of 30° corresponds to axonometric isometry https://en.wikipedia.org/wiki/Axonometry#Special_axonometries ? I haven't found the information on the perspective projection formula used for the view in MetaShape, but I assume it's axonometric (parallels seem to remain parallel, a round sphere is projected as a round circle) and not conical perspective, which is more like what we see with the eye ?

Rendering is obviously better in stereoscopic 3D. The parallax value for a stereo view, I assume that the value refers to the closest plane foreground represented ? or the center of the box ? The comfort value for the brain is between 2 and 3° for stereo reproduction on a standard-size PC screen.

What is your experience of the variation of these parameters in rendering ?

Kind regards, David.
