Member Data Documentation

◆ origin

dvec3 vsg::ViewMatrix::origin

origin value provides a means of translating the view matrix relative to the origin of any CoordinateFrame subgraphs to maximize the precision when moving around the CoordinateFrame subgraph. This is helpful for astronmically large scenes where standard double precision is insufficient for avoiding visually significant numerical errors.
