What is Cosmic Collisions?
Cosmic Collisions is an interactive GPU-accelerated physics simulation for visualizing planetary impact scenarios. Users can adjust collision parameters (impactor mass, angle, speed, density) and observe real-time dynamics of different impact types, including head-on collisions, hit-and-run encounters, and planetary mergers.
Cosmic Collisions pricing
Pricing model: Freemium
Free (open-source personal project hosted on GitHub Pages)
Cosmic Collisions pros
- Real-time GPU-accelerated simulation with adjustable physics parameters
- Multiple collision scenarios (head-on, hit and run, twins, shatter modes)
- Interactive 3D visualization with rotation, zoom, and playback controls
- Customizable visual rendering (glow, shading, atmosphere, stars, sparks)
Cosmic Collisions cons
- Requires GPU support for float texture rendering (not all browsers/devices compatible)
- Minimal in-page documentation or tutorial for parameter meanings
- Loading state visible in content—may indicate incomplete page or runtime issues
Frequently asked questions about Cosmic Collisions
What collision types can I simulate?
Giant impact, theia, head-on hit, run, twins, and shatter scenarios with adjustable parameters
What controls are available?
Drag to rotate, scroll wheel to zoom, space to pause, 'r' to restart, 'f' to follow. Speed can be adjusted (0.25x to 4x)
Why won't the simulation run?
Your GPU does not support float texture rendering, which is required for the WebGL-based simulation
