Detailed Description

Parameters

radius
oneMinusOblateness
slices	number of vertical segments ("meridian zones")
stacks	number of horizontal segments ("latitude zones")
orientInside	1 to have normals point inside, e.g. for landscape horizons
flipTexture	if texture should be mapped to inside of sphere, e.g. landscape horizons.
topAngle	GZ: new parameter. An opening angle [radians] at top of the sphere. Useful if there is an empty region around the top pole, like for a spherical equirectangular horizon panorama ( Example: your horizon line (pano photo) goes up to 26 degrees altitude (highest mountains/trees): topAngle = 64 degrees = 64*M_PI/180.0f
bottomAngle	GZ: new parameter. An opening angle [radians] at bottom of the sphere. Useful if there is an empty region around the bottom pole, like for a spherical equirectangular horizon panorama (SphericalLandscape class). Example: your light pollution image (pano photo) goes down to just -5 degrees altitude (lowest street lamps below you): bottomAngle = 95 degrees = 95*M_PI/180.0f
