a methodology flaw? and a bug in render_3?

[tarquai]

Hi and thanks for sharing your good work, I would like to work with it more BUT:

There might be a bug in render.
when using gsplat and supersplat to render, we get elongated gaussians,
look at the other issue in this forum for images: #27
After an investigation, the gaussians scale has a very small z component compared to the x,y components.
The "render" and "render_3" function process the Gaussians differently (they contain custom code).

Since gaussian splatting and rendering is well-defined. it should work with "regular" off-the-shelf gaussian splatting visualisation libraries.

Thanks.

look at the link to the other issue.
it's just a different convention for the quats (w,x,y,z) / (x,y,z,w)
