Building

Linux

1. To build this project you will require Intel Rendering Toolkit, specifically Embree 3.0 & Open Image Denoise (online version), Intel Threaded Building Blocks, CMake, and libxi-dev build-essential xorg libglfw3 libglfw3-dev libxinerama-dev libxcursor-dev (these are the packages for Debian/Ubuntu)

2. You will need to run source /opt/intel/oneapi/setvars.sh so it sets the global vars needed for building. If this doesn't work please look for this file, and source that file in the same terminal window you compile in.

3. Next you will need to run cmake -DCMAKE_BUILD_TYPE=RELEASE . this will build the cache

4. Finally you need to build it using cmake --build . --target CRender, now this will take a while.

5. Run ./CRender

Bugs/issues with building:

If you get an error such as ./CRender: symbol lookup error: /opt/intel/oneapi/oidn/1.4.0/lib/libOpenImageDenoise.so.1: undefined symbol: _ZN3tbb6detail2r15spawnERNS0_2d14taskERNS2_18task_group_contextE you need to remove every tbb package except the intel one. If if you get a glenable etc error you need to get new drivers If it cannot find embree you will need to go to /opt/intel/oneapi and move embree to a folder called embree instead of embreeX.XXX
