Detailed Description

Warper that maps an image onto the unit sphere located at the origin.

Projects image onto unit sphere with origin at (0, 0, 0) and radius scale, measured in pixels. A 360° panorama would therefore have a resulting width of 2 * scale * PI pixels. Poles are located at (0, -1, 0) and (0, 1, 0) points.

Constructor & Destructor Documentation

SphericalWarper ( float  scale )

Construct an instance of the spherical warper class.

Parameters:
scaleRadius of the projected sphere, in pixels. An image spanning the whole sphere will have a width of 2 * scale * PI pixels.

Definition at line 257 of file detail/warpers.hpp.
