Platform Release v0.41.1

This is copy pasted from the SimDynamX internal repository, so most or all of the links here direct to non-public sites.

This new Space Teams PRO version has been released and is available for download on spaceteamspro.com.

Space Teams PRO releases that start with 0. are all Beta releases, meaning we have relaxed standards for stability, performance, and backwards compatibility as we quickly introduce new features. Please contact us directly (support@SimDynamX.com) if you are interested in using Space Teams in an environment where software stability is critical.

Most notable changes since v0.40.1:

Sim Startup Refactor

• Sims now have a more structured initialization process
  • Fixed bug where Systems in a sim do not start but the SpaceCRAFT client program does start.
  • Wait for programs to declare themselves done with sync and init before continuing
  • Reliable order of operations for user code
    • All client programs will be loaded and ready before init and update functions can run
    • Init phase waits for all System init() functions to complete before continuing (change in guarantees)
• Change in SimState definitions
  • From Loading, Lobby, Runtime to Loading, Lobby, Sync, Init, Runtime
  • Loading
    • Load the sim config as a starting point, independent of any other programs
    • System load() functions are run
  • Lobby
    • Wait for other clients to finish connecting/loading, communicate and organize with other users (if applicable).
  • Sync
    • With a final user list known, enter a process where we ensure all clients are joined and warmed up before Init/Running Simstate is made available.
    • Some propagators such as SPICE start running in order to initialize the solar system environment
  • Init
    • System init() functions are run
  • Runtime
    • Timed updates begin. Physics starts moving.
    • Normal UI interaction resumes
    • System update() functions start running
    • Python Systems continue from connect_to_sim() call
      • Planned feature to allow python code to run during earlier sim states when so configured
• Sim Editor mode
  • When running a sim, it can be opened in the "Sim Editor" mode for editing
    • Role Picking screen click Open In Sim Editor
  • This stops the startup process in Sync state, so no Systems have run any init/update code, and only some specific propagators are running
  • See SIM SUSPENDED FOR EDITING at the top of the screen
  • Able to save a sim from this mode in a pristine state, unmodified from Systems or propagators running
  • Work is still in progress to add more functionality such as editing Systems, FieldEffects, their instance parameters, and system assignment to entities

New Sim Wizard

• Interactive new-sim-creation UI
  • Choose a planetary body to center your new sim on
  • Choose starting time and location on the surface or in orbit
  • (Coming soon) select scenario to start at chosen location
  • Open your sim, either to edit/save it or to run immediately
• Still in active development; more features coming soon.

Demos

• Fixed ISS Live sim
  • Data from the public source may still be stale

Dynamics

• Added "Assumed Inertial Frame" capability to ST_Rigid_Body
  • By default, ST_Rigid_Body propagator uses Solar System Barycenter / J2000 as the assumed inertial frame.
  • If the simulation does not have the whole solar system present and contributing to the Gravity FieldEffect, this assumption will cause a mismatch between sim behavior and a reduced-order model that also does not include the whole solar system.
    • For example, if your sim only includes Earth and Moon gravity, the gravity from the Sun and Jupiter that is implied by the relative motion of the solar system barycenter entity will cause your sim to mismatch from a sim that uses earth-centered inertial frame as its assumed-inertial frame and also only has Earth and Moon gravity.
  • We have added the capability to override the Assumed-Inertial Frame that an entity propagates with
    • EntityRef parameter with key { "Dynamics", "PropagatorConfig", "AssumedInertialFrame" } on propagated entity
• Fixed bug in Velocity Override PhysEffect handling within ST_Rigid_Body propagator
• Added polyhedral gravity FieldEffect
  • See packages\EnvironmentalModels\Gravity\src\Gravity_Polyhedral.cpp

3D Drawing Interface

• FramedDrawer Varied Fixes and Potential Performance Improvements
• SimGlobals::DrawLine() function
  • Spawns a line drawer entity and returns its reference.

General

• Remove old camera image export code
  • Now only st.camera functions and Camera-type Entity are what is used to take capture images from the sim
• Clean up many old assets
• Added offline star and planet rendering system, mostly in support of spaceflight navigation systems research
• Fix unreal client crash on problem during planet entity spawning
• Many minor fixes and adjustments

Key Known Issues

Also look at https://github.com/SimDynamX/SpaceTeamsPRO/issues to see all publicly reported issues and their current status.

• (Maybe resolved) https://github.com/SimDynamX/SC_Platform/issues/1491 https://github.com/SimDynamX/SC_Platform/issues/2235 Realtime Capture SkyLight sometimes has improper lighting
• (Greatly reduced impact) Various small GMRAD issues involving cube-side edges https://github.com/SimDynamX/SC_Platform/issues/783
• https://github.com/SimDynamX/SC_Platform/issues/1739 Some jitter in specific situations, probably involving a time synchronization issue
• Don't yet have a way to set up Systems on Entities in the SpaceCRAFT sim editing utilities; still requires text-editing the sim config for now.
• Planet small-scale surface detail normal map (detail lighting) 90 degrees out of alignment when at the poles
• Euler angle singularities
  • DCM_to_Euler321 returns a wrong rotation when a +- 90 degree pitch (y-rotation) DCM is passed in
• Outliner / Hierarchy Go To functionality is broken
• ST_Rigid_Body Propagator has issues when ResidentFrame is not SSB. Also applies to Propagator system when PropagationFrame mismatches with ResidentFrame #2872
• Surface collisions not working on the Moon in particular
