Solution to a task on ray tracing algorithm

Ray Tracing

Ray tracing task requirements

During the Computer Graphics course students of the CMC Faculty of Lomonosov MSU are offered to solve a task on ray tracing algorithm and visualize 1-3 scenes using the algorithm.

Obligatory requiremnts are as following:

1. implementation of local illumination with Phong's model (or others);
2. implementation of shadows;
3. implementation of mirror reflections;
4. using at least 3 different materials;
5. using at least 2 different geometric primitives;
6. using at least 1 light source;
7. 1 scene rendering should take no more than 1 second (for processor like 6-cores AMD Ryzen 5 3600);
8. minimal resolution for an image is 512x512.

Students are also offered to perform additional features.

Scene 1

Basic primitives: spheres, cube.
Extra features implemented on the scene:

1. Additional geometric primitives: parallelepiped, plane;
2. 2-order surface: cylinder;
3. Elimination of the straggering effect;
4. Multithreading implementation.

High resolution version (1920x1080): scene1_high_resolution.jpg.

Scene 2

Basic primitives: spheres, plane.
Extra features implemented on the scene:

1. Using environment spheerical maps (observatory);
2. Using textures (NASA logo).

High resolution version (1920x1920): scene2_high_resolution.jpg.

Run

Solution to the task is written on C++: ray_tracing.cpp.

To compile the program do:
$ cmake .
$ make -j 4

To run the program do:
$ ./ray_tracing

Following parameters are available:
"-out" --- file to write a result in (should have .jpg format, scene.jpg by default);
"-scene" --- number of scene (1 or 2, 1 by default);
"-threads" --- number of threads (8 by default).

Example: $ ./ray_tracing -scene 1 -threads 4 -out "scene1.jpg"
