RayTracing

This project is made by Taeil-Nam, GunJoong-Kim

Limitation

• Program doesn't use GPU, only use CPU.
• Not supported Real-Time Rendering.
• In "PATH" rendering mode, program uses Path Tracing and it takes a more time to rendering.
• In "PATH" rendering mode, if you want to see clean image, increase SAMPLE_PER_PIXEL in inc/minirt.h:17
  • Recommend increasing the value at least 500 but rendering would be TOO SLOW..

Getting Started

Prerequisites

• Intel CPU Mac
• MacOS Version = 12.6.2
• Clang Version = 12.0.0
• MiniLibX (graphics library)
• swiftc 5.7.2 (to compile MiniLibX)

Installation

1. Git clone

   $> git clone https://github.com/Taeil-Nam/RayTracing.git

2. Move to project directory

   $> cd RayTracing/

3. Use "make" command to create program

   $> make

Usage

Execute the program with valid map file as argument.

Valid map file name format = map/[file name].rt

Ex) rendering map "box.rt"

$> ./RayTracing map/box.rt

please refer to the Demo video

📌All file names with "_bonus" shown in the video have been changed to file names with "_bonus" removed.

Rendering mode

You can select the rendering mode by editing the code.

1. PHONG(default mode)
   • Uses Phong Reflection model.
2. PATH
   • Uses Path Tracing model.

Ex) in src/main.c:49 minirt->illumination = PHONG; or minirt->illumination = PATH;

Features

• Ray Tracing
• Phong Reflection
• Path Tracing
• Rendering object (sphere, plane, cylinder, cone)
• Camera
• Multi-spot light
• Checkerboard texture
• Image texture
• Bump map (Normal map) texture
• multi-threading
• BVH (Boundary Volume Hierarchy)

Results

• In "PATH" rendering mode, SAMPLE_PER_PIXEL = 2000
