Detailed Description
template<typename texture_t>
class reg23::SinogramClassic3D< texture_t >
class reg23::SinogramClassic3D< texture_t >
A 3D texture stored for access by the CPU, structured for storing an even distribution of values over the surface of S^2, according to the HEALPix mapping. ToDo: citation here.
- Template Parameters
-
texture_t
Texture sampling is done using spherical coordinates $(r, \theta, \phi)$, but only the first dimension $r$ actually corresponds to the texture coordinate in the volume data. Across two dimensions the values are stored according to a rectangular tesselation of the HEALPix spherical projection.
This object does not own the data it provides access to, it just holds a pointer to it
Both copy and move-constructable.
