This is the implementation of the ray tracing algorithm on the CPU

|
|
|
|
|
|
|
# Build
|
|
The supported platforms are Windows and Linux. On Linux you need to manually install GLFW 3:
|
|
```
|
|
sudo apt install libglfw3-dev
|
|
```
|
|
After that you can build the program:
|
|
```
|
|
make
|
|
```
|
|
The executable you need to run is `ray_trace.exe`.
|
|
|
|
# Usage
|
|
You need to run the renderer from the command line providing it the proper arguments:
|
|
```
|
|
./ray_trace.exe --scene scene_0.txt --threads 16 --init-scale 2
|
|
```
|
|
This will open a window with the rendered scene. You can more around with WASD and change the camera direction with the mouse. You can also make screenshot by pressing the spacebar!
|
|
|
|
You should use a number of threads equal to the number of CPU cores. The `--init-scale` lowers the initial resolution of the scene when moving the camera and can be any power of two between 1 and 16 (1, 2, 4, 8, 16).
