Beart is my personal Ray Tracing Render for studying. It is inspired by many open-source renderers. The project is still under development.
Clone the repository and submodules:
$ git clone --recursive https://github.com/bearprin.git
$ git submodule update --init --recursiveUse CMake to generate the build system for your favorite IDE or compiler. For example, on Mac/Linux, you can use the following commands to generate a Makefile and build the project:
$ cd beart
$ cmake -B build -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles"
$ cmake --build build -jFind the executable file in build/bin directory.
$ ./build/bin/beart -s scenes/{scenes_file_path} -o {output_file_path}where -s is the scene file path, -o is the output file path.
The default output file path is the "output/{scenes_file_name}_{timestamp}.exr"
We recommend tev and HDRView to view the output image.

Since scene data is very important for the render, I have transferred some scene files from other open-source renderers.
I would like to thank the scenes files and models from darts and ecse689.
