SoftRayTracer

中文版说明点击这里

This is a soft ray tracing renderer based on the Monte Carlo algorithm.(It doesn't use any third-party rendering APIs.)

Suppose you are in the root directory of this project.

Then:

1.make a new folder named "build".

mkdir build

2.enter this folder.

cd build

3.generate the project with cmake.

cmake ..
cmake --build .
cmake --install .

4.then an .exe file named ray_tracer.exe will be generated in the bin folder.

5.after running the program, an image named "img.png" will be created which represents the rendering result.

6.you can change the scene by changing the code in config.cpp.

eg:

SceneType configScene = SceneType::ROOM_TEAPOT;

Click to see the rendered image seperately:

• SceneType::ROOM_SIMPLE
  
• SceneType::ROOM_SIMPLE_BUNNY
  
• SceneType::ROOM_COMPLEX_BUNNY
  
• SceneType::ROOM_TEAPOT
  
• SceneType::ROOM_MATERIAL_BALLS
  
• SceneType::ROOM_NORMAL_MAP
  

7.Because the rendering process is time-consuming, you can change the resolution and sampler number of the image by changing the value resolutionScale and configSamplersPerPixel in config.cpp.

eg:

int resolutionScale = 16;//this is slow but with more resolution
int configSamplersPerPixel = 10;//this is slow but with more samplers

---

int resolutionScale = 2;//this is fast but with less resolution
int configSamplersPerPixel = 1;//this is fast but with less samplers

you can get some details in the document folder.(in progressing...)
