planar_angle2solid_angle_fraction, solid_angle_fraction2planar_angle,
rotate_from_nth_canonical, random_vector_on_spherical_cap): Add
docstrings.
| Arun Isaac |

planar_angle2solid_angle_fraction, solid_angle_fraction2planar_angle,
rotate_from_nth_canonical, random_vector_on_spherical_cap): Remove
space between function name and bracket.
| Arun Isaac |
| 2021-03-15 | Implement simplified cone sampling algorithm.•••* contrib/cone-vector.py: Don't import tan.
(random_vector_on_spherical_cap): Implement simplified algorithm that
directly samples the surface of the sphere instead of sampling a disk
and projecting it onto the surface.
| Arun Isaac |
| 2021-03-15 | Vectorize functions.•••* contrib/cone-vector.py: Import where.
(planar_angle2solid_angle_fraction,

(random_vector_on_spherical_cap): Build random vector without
concatenation.
| Arun Isaac |
| 2021-03-10 | Remove surface area computation.•••Now that we are computing solid angle fractions, there is no need to
compute the total surface area of the sphere.
