Explore Curiosity Navcams 3D images in Oculus Quest.
Stereoscopic view.

Oculus Quest tested (6DoF headset/controllers).
Oculus Browser (tested Quest update > 17.0).
No installation.
In Oculus Quest, open Oculus Browser and link (let browser finish loading before "Enter VR").
File sol1151_wheel_measure.glb shows one of Curiosity's six wheels on the lower right. Any Navcam image with wheel(s) is selected because a wheel is used in Blender to scale the 3D mesh. The author of Blender-Navcam-Importer has stated that, "resulting mesh...is in no way scientifically accurate". Nevertheless, the result does not appear distorted or unusual.
If no Oculus Quest (tested 2018 9.7" iPad/iPadOS 13/Safari, Windows 10/Google Chrome/Firefox, Raspberry Pi 3 B+/Raspbian Buster).
Let browser finish loading before "Enter VR".
In front are two images combined as one stereoscopic view using three.js. The left and right Navcams are separated by 42 centimeters apart so it is not what a person would see standing there, someday. Humans IPD averages from 5.1 to 7.7 cm.
The image on the left is a monoscopic view of NLB_524534514EDR_F0562034NCAM00280M_.jpeg.
The 3D model on the right is constructed from two images NLB_524534514EDR_F0562034NCAM00280M_.jpeg and NRB_524534514EDR_F0562034NCAM00280M_.jpeg using Blender-Navcam-Importer.
This project uses images taken by Curiosity Navcams.
Lot of excellent materials. Do a search for "raw images".

The Sol 1431 VR experience is created from left image.
And by changing "NLB" to "NRB", get corresponding right image.
Sometimes a left image is available but a matching right image is not available. Move to other images.

To find the image used to make sol1151_wheel_measure.glb, enter 1151 for Sol and sort by "oldest to newest". It should be the 13th image (2015-11-01T21:33:08.000Z).

A Blender addon is used to import Curiosity Navcams.
https://github.com/phaseIV/Blender-Navcam-Importer
The Blender-Navcam-Importer github has an excellent introduction about the addon.
Blender 2.82 is used to export "glTF Binary" sol1511-wheel-measure.glb with Decimate Modifier(Ratio 0.1) and Draco compression.
