Typed hemispherical alt/az grid sampler. More...

#include <siderust/sky_grid.hpp>

Public Member Functions
SkyGrid &	with_alt_range (qtty::Degree lo, qtty::Degree hi)
	Restrict the altitude range (builder, e.g. a 10°..90° horizon mask).
std::vector< SkyGridCell >	cells () const
	Materialise every cell of the grid.
std::size_t	size () const
	Number of cells the grid materialises.

Static Public Member Functions
static SkyGrid	uniform (qtty::Degree step)
	Uniform grid with equal altitude and azimuth steps over [0°, 90°).
static SkyGrid	with_steps (qtty::Degree alt_step, qtty::Degree az_step)
	Uniform grid with independent altitude and azimuth steps over [0°, 90°).
static SkyGrid	equal_area (qtty::Degree alt_step, qtty::Degree az_step_at_horizon)
	Equal-area grid: azimuth count per altitude ring scales with cos(alt).

Detailed Description

Typed hemispherical alt/az grid sampler.
