The quad sphere has two principal characteristic features. The first is that the mapping consists of projecting the sphere onto the faces of an inscribed cube using a curvilinear projection that preserves area. The sphere is divided into six equal regions, which correspond to the faces of the cube. The vertices of the cube correspond to the cartesian coordinates defined by x = y = z on a sphere centred at the origin. For an Earth projection, the cube is usually oriented with one face n… WebIn cubic projections, pixels on a sphere are projected onto six faces of a cube. Six cube faces are then arranged on a planar image for image/video encoding. To date, there exists two types of cubic projections: the standard cubic projection and the offset cubic projection. Standard cube can be seen as a special case of offset cube. Standard Cube

Comparison Of Spherical Cube Map Projections Used In

In mathematics, a stereographic projection is a perspective projection of the sphere, through a specific point on the sphere (the pole or center of projection), onto a plane (the projection plane) perpendicular to the diameter through the point. It is a smooth, bijective function from the entire sphere except the center of projection to the entire plane. It maps circles on the sphere to circles or lines on … WebProjection¶ Flat Flat mapping gives the best results on single planar faces. It does produce interesting effects on the sphere, but compared to a sphere-mapped sphere the result looks flat. On faces that are not in the mapping plane the last pixel of the texture is extended, which produces stripes on the cube and cylinder.
