README

A Renderer is based on ray tracing.

How to use

Run CMakeLists.txt

cmake -B build      # 生成构建目录
cmake --build build # 执行构建

Qt

The UI is based on Qt 5. Before using CMakeLists.txt, please change Qt's path here

#CMakeLists.txt
....
#Change Qt Path
set(CMAKE_PREFIX_PATH "D:/Qt/5.15.2/mingw81_64")
....

Example

If you don't want to use Qt as the framework, just go to example and run run.bat in WINDOWS OS.

OpenMP

The Render is accelerated by OpenMP. Make sure your compiler support it.
