I’ve been working on this project for the better part of 2020. So happy to be able to release it to the world. Official article: https://www.nasa.gov/feature/rocks-from-other-worlds-now-virtually-available
Uses ThreeJS to show interior CT data of each rock. Example: https://ares.jsc.nasa.gov/astromaterials3d/explorer/?sample=60639-0

Really interesting, and your work is great. Did you do the rocks scans ?

The scans were done by Erika Blumenfeld over the past 5 years. Thousands and thousands of digital Hasselblad photos processed using SFM photogrammetry.

At first it’s like - “Hm. Alright, these are very handsome rocks.” Then you realize you can cut through the rock on every axis and see volumetric scans at each step - daaaaaaaaaamn, nice.

Great work! By the way, have you tried anisotropic filtering for the textures? It might improve the texture quality on the sides.

Thanks very much for the tip. I hadn’t investigated this before. Do you mean on the mesh texture or the slice textures?

Thanks again. Just implemented anisotropic filtering on all textures.
I just realised, is that intentional that panning is only possible horizontally ?

not really. I’m not using OrbitControl so it’s a bit different than usual. You can pan up and down if you use the arrows under the eye menu icon.

Nice! I was thinking on both, but to be honest it doesn’t need to be crazy, sometimes I found that just setting it to 2 already removes the blurry look: Math.min(2, renderer.capabilities.getMaxAnisotropy())
@bfeist what SFM Photogrammetry software do you use? Reality Capture?
@bfeist what license applied to the code ? thinking of reusing the cubeNav.
Amazing work, congratulations.
We have an Imaging and analysis department in the museum I work at, will need to show them this.
