As such, the ray tracing method allows for the inclusion of multiple (and different) non-omnidirectional sound sources as well as a variety of reflection patterns (from fully specular to ideally diffuse). Moreover, to increase efficiency, ray bundles can be applied instead of single sound rays. Such bundles can display a circular or polygonal cross-section (Kuttruff 2017). The respective procedures are typically referred to as cone tracing or pyramid tracing (Stephenson 1996).

The work provided here is an initial proof of concept to the potential of combining GA and generative programming in practical RT applications. Many future improvements to the RT procedure we presented are possible. For example, blades in other kinds of GAs can seamlessly represent more complex 2D and 3D primitives like spheres and quadrics (Easter and Hitzer 2018; Hitzer 2019). Another possibility is to develop the algorithm to handle beam and cone tracing on flat surfaces (Nidd, Mann, and Black 1997; Schmitz et al. 2009) using HGA formulation of SDs. The use of GA-based generative programming tools like GMac would then be essential to creating efficient implementations from GA formulations. Highly-performant RT implementations based on GPU parallel hardware acceleration are also possible using this approach.
