README

A Renderer is based on ray tracing.

How to use

Run CMakeLists.txt

cmake -B build -DCMAKE_PREFIX_PATH="Path_TO_QT5"
cmake --build build

Qt5

The UI is based on Qt5, so you must specific the the QT path.

Example

If you don't want to use Qt5 as the framework, just go to example and run run.sh on Linux OS.

cd example

OpenMP

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