Zero123plus (https://github.com/SUDO-AI-3D/zero123plus) output views are a fixed set of camera poses:

Azimuth (relative to input view): 30, 90, 150, 210, 270, 330.
Elevation (absolute): 30, -20, 30, -20, 30, -20.

To generate the images from Zero123++ it's easier to just use:

and enable both background removals

StableSAM is usually used to remove backgrounds:

    Lambertian fragment shaders make a difference, but only if you normalise the
    vertNorm in the fragment shader. Most of the time you won't notice the difference.

    These are oscillators that have Cutoff and Resonance
    as a pre/before-fact filter rather than a post/after-fact
    filter.

    We do this by constructing a Sawtooth or Squarewave from
    additive synthesis of sinusoids. This allows us to get
