Tutorials on Rays and Billiards

3D Investigate Rays and 3D Billiard are tools that not only allow you to visualise how sound propagates in your room model, but also allow you to identify model issues such as holes in the geometry and whether your source position is appropriate, as well as acoustic effects such as flutter echoes and focusing.
