Simple Real-time ASCII raytracer in terminal, written in Rust with animation support.

• Real-time 3D scene rendering in ASCII
• Animation support (orbiting cameras, pulsing objects, moving lights)
• Customizable character palette for different effects
• Automatic adaptation to terminal size

cargo build --release

cargo run --release

# Set resolution
cargo run --release -- --width 120 --height 60

# Change FPS

cargo bench

The project tries to follow clean architecture principles:

• src/scene/ - geometry, camera, animations
• src/renderer/ - ASCII rendering
• benches/ - performance benchmarks

Options:
  -p, --palette <PALETTE>  ASCII palette (lightest to darkest) [default: ASCII70]
  -f, --fps <FPS>          Frames per second (0 = single frame) [default: 24]
  -W, --width <WIDTH>      Width in characters
  -H, --height <HEIGHT>    Height in characters
  -h, --help               Display help

• Default (ASCII70): `.-':_,^=;<>+!rc*/z?sLTv)J7(|Fi{C}fI31tlu[neoZ5Yxjya]2ESwqkP6h9d4VpOGbUAKXHm8RD#$Bg0MNWQ%&@
• Simple: .:-=+*#%@
• Blocks: ░▒▓█
