2021-03-16Deal in solid angle fractions, not absolute solid angles.Arun Isaac
* src/extent-sampling.sc (volume-cone): Use solid-angle-fraction->planar-angle instead of solid-angle->planar-angle. * src/nd-random.sc (planar-angle->solid-angle): Rename to planar-angle->solid-angle-fraction and return a solid angle fraction. (solid-angle->planar-angle): Rename to solid-angle-fraction->planar-angle and accept a solid angle fraction. (hollow-cone-random-vector): Use planar-angle->solid-angle-fraction instead of planar-angle->solid-angle. (beta-inc-unnormalized, incomplete-wallis-integral): Delete functions. * include/nd-random.h (planar_angle_to_solid_angle): Rename to planar_angle_to_solid_angle_fraction. (solid_angle_to_planar_angle): Rename to solid_angle_fraction_to_planar_angle. * scm/nsmc/wrap.scm (planar-angle->solid-angle): Rename to planar-angle->solid-angle-fraction.

2021-02-26Rename subsampling-random-vector to cone-random-vector.Arun Isaac
* scm/nsmc/wrap.scm: (subsampling-random-vector): Rename to cone-random-vector. * src/nd-random.sc (subsampling-random-vector): Rename to cone-random-vector. * include/nd-random.h (subsampling_random_vector): Rename to cone_random_vector.
2021-02-03Move source files and headers to separate directories.Arun Isaac
* extent-sampling.h, gaussian-nd-random.h, nd-random.h, oracles.h, utils.h: Move into include directory. * extent-sampling.c, gaussian-nd-random.c, nd-random.c, oracles.c, utils.c: Move into src directory. * CMakeLists.txt: Set include as include directory. Look for source files inside src directory.
