Does anyone have any idea how I can generate a 3D point plot like what I want without having an enormous file size? If it helps, I don't need to be able to rotate such a plot in 3D.

Does anyone have any idea how I can generate a 3D point plot like what I want without having an enormous file size and taking my computer a day to produce? If it helps, I don't need to be able to rotate such a plot in 3D.

I've been using random walk Metropolis to sample from the (unnormalised distribution) which is defined as $p(r)\propto e^{-100 r}$, where $r$ is the perpendicular distance of a point in 3D space from the surface of a,

which generates sample paths that look like,

over time.

I want to draw a 3D point plot of all the sampled values where each of the points is a cow shape. I have tried doing this with,

but does not scale well to 1000s of points, which is unsurprising given that each cow is a fairly complex 3D graphic. I have tried downsampling the cow's polygon coordinates and using these as markers instead by,
