Struct usd::pxr::usd_geom::Mesh

#[repr(C)]
pub struct Mesh { /* private fields */ }

Encodes a mesh with optional subdivision properties and features.

As a point-based primitive, meshes are defined in terms of points that are connected into edges and faces. Many references to meshes use the term ‘vertex’ in place of or interchangeably with ‘points’, while some use ‘vertex’ to refer to the ‘face-vertices’ that define a face. To avoid confusion, the term ‘vertex’ is intentionally avoided in favor of ‘points’ or ‘face-vertices’.

The connectivity between points, edges and faces is encoded using a common minimal topological description of the faces of the mesh. Each face is defined by a set of face-vertices using indices into the Mesh’s points array (inherited from UsdGeomPointBased) and laid out in a single linear faceVertexIndices array for efficiency. A companion faceVertexCounts array provides, for each face, the number of consecutive face-vertices in faceVertexIndices that define the face. No additional connectivity information is required or constructed, so no adjacency or neighborhood queries are available.
