Stargazer

Objectives

I am building a star explorer application : Stargazer.

This project serves as a proxy for me to get better at:

• Rust
• ECS based architecture (with Bevy)
• Basic 3D engine manipulations (projection matrices, quaternions, transforms..)
• Astronomy fancy details
• Shaders ? Maybe ?

Current status

Stargazer.2021-09-30.22-33-14.mp4

Stargazer is in early development (started early September 2021). The current envisioned features implemented/to be implemented are listed below.

Done

• Custom 3D to 2D projection
• Equatorial grid render from paths
• Constellation render from csv file
• Camera movement from mouse
• RA/DEC star coordinate fetching from Some(api)
• Processing star data to theta/phi coordinates
• Drawing stars individually from sprite
• Multiple states (menu, config, etc...)
• GUI button animation
• FOV smoothing
• Orbit camera smoothing

To Do (not in order)

• Correct bug with multiple kb inputs for state transition
• Showing stars names
• Showing ra/dec values on screen border (WIP)
• Adaptive grid resolution
• Adaptive scene generation (generate only what can be seen by the camera)
• Align 3D world coordinates to RA/DEC and cardinal points
• Aesthetic concerns (make it beautiful) (When I'm Bored)

How to use

With Rust installed, run one of the binaries available:

cargo run --bin app --release

First compilation will take some time, see dynamic linking for faster compilation times.
