miniRT 107/100

Basic raytracing engine from scratch using MiniLibX.

Build it yourself

• sudo apt-get install gcc make xorg libxext-dev libbsd-dev
• (Only using WSL) Install XMing on your Windows 10 (just click next, it's ok)
• make all

.rt file syntax

• R [width] [height] // display resolution
• c [X],[Y],[Y] [rotation X],[rotation Y],[rotation Z] [FOV] // camera (rotation as normalized vector)
• A [intensity] [R],[G],[B] *// ambient lighting
• l [X],[Y],[Z] [intensity] [R],[G],[B] [directional, 0 or 1] //lighting
• sp [X],[Y],[Z] [radius] [R],[G],[B] [reflection rate] [specular rate] // sphere
• tr [X],[Y],[Z] [X],[Y],[Z] [X],[Y],[Z] [R],[G],[B] [reflection rate] [specular rate] // triangle
• cy [X],[Y],[Z] [X],[Y],[Z] [R],[G],[B] [diameter] [height] [caps, 0 or 1] [reflection rate] [specular rate] // cylinder
• ds [X],[Y],[Z] [X],[Y],[Z] [radius] [reflection rate] [specular rate] // disc
• sq [X],[Y],[Z] [X],[Y],[Z] [side size] [R],[G],[B] [reflection rate] [specular rate] // square
• cu [X],[Y],[Z] [side size] [R],[G],[B] [reflection rate] [specular rate] // cube
• py [X],[Y].[Z] [side size] [height] [R],[G],[B] [reflection rate] [specular rate] // pyramid

Controls

• WASD/Shift/Control for camera translation
• Arrow keys for camera rotation
• Q for camera switching (it's looped)

Usage

• export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2}'):0.0 // WSL only
• export DISPLAY=localhost:0.0 // WSL(1) only
• ./miniRT <configuration_file.rt> [--save] // --save: save render as bmp file
• Relish
