ludus::foundation::geometry::SurfaceMeshVertex¶

Struct

One render vertex: a shared position plus per-patch shading data.

Vertices of different patches at one point copy the same Position bitwise and name the same PositionIndex, while their normals and parameters may differ (a normal or parameter seam). Parameter is never a texture coordinate.

Fields¶

Position¶

math::Vector3 ludus::foundation::geometry::SurfaceMeshVertex::Position {}

Bitwise copy of the referenced SurfaceMeshPosition.
