Rover visualization and other apps, For discussions of ways to view and understand the mission Options

[Phil Stooke]

Hi Everyone. I am starting a thread for discussions of the many ways people are interacting with Perseverance (and potentially other missions). These subjects are getting spread around other threads and maybe getting in the way of basic mission updates etc., so this is a place to bring this together. Feel free to contribute to it.
I am going to start by asking about panoramas - what's the best way to do this with Perseverance images, especially Navcam images from every end of drive?

Hi all,

Wanted to introduce you to (yet another) rover and terrain visualization web app which I hope will help folks become familiar with Perseverance and the Jezero Delta.

My Rover3D page mimics actual MER and MSL driving tools. The Perseverance rover model derives from the official JPL public release model, but has been heavily modified to finish incomplete texture and material mapping, and has been split into articulable parts which you can control via sliders, similar to the official rover driving tools. Or you can send the arm, RSM, and HGA to one of several selectable canonical poses, matching MSL's standard defined poses (note: the default arm pose in the public release model, with upper arm horizontal and forearm vertical, is non-standard and not generally used).

The Jezero Delta front-range terrain is composed of a HiRISE ortho-rectified luminance image (downscaled to 50cm/px for performance), blended with one of Justin Cowart's masterpiece CRISM color mosaics, and draped over a MOLA DTM.

Click "ABOUT" in the upper-left corner for general information, controls, and credits. The controls take a minute to get used to, but are optimized to help you scoot around the scene quickly and freely. Quick synopsis:

• Left-click and drag to rotate view around a center point
• Right-click (or hold shift and left-click) and drag to pan the view up/down/left/right
• Double click anywhere on the terrain to center the view at that point
• Press "r" key to center the view over the [r]over
• Press "d" key to [d]rop the rover onto the terrain behind your mouse cursor

Explore the northern Delta approach strategic route (cyan), southern approach route (blue), and the delta entry route (yellow)!

Planned future work:

• Some form of driving, wasd key-based and/or waypoint-based
• Sync to telemetry (after SPICE kernels are made available)
• Add named features and points of interest markers
• Render camera frustums
• Support local Navcam/Mastcam-Z terrain meshes

I hope you find this useful!
