Orion

Simple raytracer.

Requirements

general

• OpenGL 3.3 compatible hardware*
• g++ (with c++17 support)
• make

libs

• GLEW*
• glfw3*
• GL*
• GLU*
• assimp

other

• GLM*
• GLAD* (Included in this repository for GL 3.3 Core)
• tqdm.cpp (See Setup below)

* - denotes libraries required by viewer and are not necessary for the raytracer.

NOTE: If you are compiling libraries from sources remember to modify LDPATHS in Makefile to contain paths with compiled libs.

Building and running

Setup

1. Download tqdm.cpp submodule

   @> git submodule update --init --recursive

Raytracer

1. @> make raytracer
2. @> ./build/raytracer --help to get list of commands
   • To use raytracer with point lights defined in rtc file: ./build/raytracer path/to/scene.rtc
   • If no point lights are defined, BRDF pathtracer will run

Viewer

1. @> make viewer
2. @> ./build/rviewer path/to/config.rtc
