Practice version of miniRT that implement Ray Tracing in One Weekend by Peter Shirley using Minilibx, simple C library that manage GUI in macOS.

• ray-tracing-the-next-week-mlx

• macOS 10.14+
• clang 11.0+
• Minilibx 20200219_beta (Already in project src!)
• Norm 2.0.2 - C code standard in 42

Minilibx is available on macOS and Linux, but there are only macOS ver. mlx in this project. So this project ONLY runs on macOS 😢

$ make
$ ./weekend 2

./weekend (chapter) (--save)

• chapter : Required. Chapter number that execute (2 ~ 13)
• --save : Optional. Save Image in bmp format. When this flag is off, it's running through Minilibx.

🎉 --save option work well! Sample bmp files are in sample folder.

• 2. Output an Image
• 3. The vec3 Class (Same result of ch2)
• 4. Rays, a Simple Camera, and Background
• 5. Adding a Sphere
• 6. Surface Normals and Multiple Objects
• 7. Antialiasing
• 8. Diffuse Materials
• 9. Metal
• 10. Dielectrics
• 11. Positionable Camera
• 12. Defocus Blur
• 13. Where Next? (Without Dielectrics and Defocus Blur)

🚨 Last Example (Chapter 13) renders 125 spheres, so it will take few hours to render.

🚀 If you want fast rendering, fix PTHREAD_CNT (Numbers of threads to render), ANTI_SAMPLES (Samples of antializing) and REFLECT_DEPTH (calculate times of ray reflecting) in minirt_const.h to optimize rendering time.
