I have started work for the source directivity of the ray tracer. The idea is to implement the drectivity as a random sampling of the rays on the sphere from the distribution induced by the source directivity. This requires to sync a number of features with the source directivity for the ISM, in particular, the energy should be matched, which requires to know the integral of the source directivity patterns. Ideally, we should store all of this in easy use classes.
[X] Energy matching with ISM (can be done by using rejection sampler efficiency to estimate volume)
[X] Volume/Area functions for cardioid
[X] Add interface to provide ray directions to the C++ engine.
[X] Power spherical distribution sampler is implemented
[ ] Power spherical distribution pdf (not needed atm).
[X] Rejection sampler
[X] Sampler for Cardioid and family distributions on the sphere (using rejection sampling)
[X] The
SphericalHistogramclass provides a way of testing distributions on the sphere via statistical tests.[X] directional histograms in libroom.Microphone using a kd-tree
[X] Tests: statistical tests, monte-carlo vs regular integration, compare energy and rt60 vs ISM
[X] docstrings
[X] Doc building ?
