This project is an introduction to the beautiful world of Raytracing. Once completed you will be able to render simple Computer-Generated-Images and you will never be afraid of implementing mathematical formulas again. Our first raytracer handle the followings:
- Ambient, diffuse and specular lightning (phong effect)
- Multiple lights colors and intensity
- Simple reflection (does not handle the light reflection)
- Simple refraction (does not handle light source refraction nor inside objects... yet)
- The followings primitive objects : Planes, Spheres, Cylinders, Cones(simple or doubles) and Triangles
- Anti-aliasing (optional)
- Multi-threading (not allowed during the project, but added after)
- Texture map and bump map (only with diffuse lightning, handling on ambient lightning needs to be done)
Possible upgrades coming in a near futur:
- Limit angle on refraction
- Handling of objects inside transparent(refraction) ones
- More primitive objects such as Torus, squares, cubes, pyramides, maybe?
- Better light blending
- Soft shadows
The goal of the program is to generate images using the Raytracing protocol. Those computer-generated images will each represent a scene, as seen from a specific angle and position, defined by simple geometric objects, and each with its own lighting system.
MiniLibX for Linux requires xorg, x11 and zlib, therefore you will need to install the following dependencies: xorg, libxext-dev and zlib1g-dev. Installing these dependencies on Ubuntu can be done as follows:
sudo apt-get update && sudo apt-get install xorg libxext-dev zlib1g-dev libbsd-dev
- Clone the project.
git clone git@github.com:ricardoreves/42-minirt.git
- Navigate to the project directory.
cd 42-minirt
- Compile the MiniRT. (You can ignore the Minilibx compilation warning)
make
- Run the MiniRT with a scenes.
./minirt scenes/wolf.rt
