CG Engine

This is my implementation of a graphics engine for Stuyvesant High School's MKS66 Computer Graphics course. Everything is written from scratch in C++.

Features

• Custom vector and matrix math
• Stack-based structure for relative coordinate systems
• Polygon drawing and rendering for boxes, spheres, toruses
• Phong reflection model for lighting
• Bezier and hermite curves

Features to implement

• Mesh support for .obj files
• Animation
• Custom/multiple lighting

Usage

Insert commands into script per line

Valid commands:

• sphere [x] [y] [z] [r] | render sphere centered at (x,y,z) with radius r
• torus [x] [y] [z] [r] [R] | render torus centered at (x,y,z) with thickness r and distance R from center
• box [x0] [y0] [z0] [h] [w] [d] | render box with one corner (x0,y0,z0) and height h, width w, depth d
• push | add new coordinate system
• pop | leave current coord system and go to previous coordinate system
• clear | clears screen
• display | displays using ImageMagick
• save [filename] | saves image as png
• rotate [x/y/z] [deg] | rotates coordinate system by deg degrees in either x, y, or z axis
• scale [a] [b] [c] | scales each axis by a, b, c
• move [dx] [dy] [dz] | translates coordinate system by dx, dy, dz in x,y,z directions

To run the script, run make in terminal

Note for WSL, imagemagick might be janky, I used XMing (make sure to run export DISPLAY=localhost:0 before each session)
