Pre-Trained Neural Point Clouds (PT-NePC)

Inspired by Neural Radiance Fields (NeRF)

Recalculate all objects origin, scale to unit sphere, project to Vertex Colors

• bpy.ops.object.origin_set(type='GEOMETRY_ORIGIN', center='BOUNDS')
• Normalise the scale in blender (ref).
• The margin for a unit cube to fit in a unit sphere is to scale each component by 0.55 after -1 to +1 normalisation.
• Convert to PLY with textures projected to Vertex Colors.

Possible filtering of meshes

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

    Benching like this never reflects real world scenarios,
    but it does give you a rough idea of the costs involved.
