Build

This is a project on codebase of MyRenderer, so building is the follows:

mkdir build
cd build
cmake ..
cd ..
cmake --build build

Run

You can run an arbitrary scene, but scenes with lightcuts configuration are these 3 demos:

build/MyRenderer desk
build/MyRenderer desk-red
build/MyRenderer bedroom
