Sphere cube projection
WebThere are two common methods of representing environment maps, cubic and spherical, the later also known as equirectangular projections. In cubic maps the virtual camera is surrounded by a cube the 6 faces of which have an appropriate texture map. 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 …

WebApr 26, 2024 · The stereographic projection is a mapping (function) that projects a sphere onto a plane. The projection is defined on the entire sphere, except the point at the top of the sphere. For the object below, the curves on the sphere cast shadows, mapping them to a straight line grid on the plane. 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.
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…
