BMesh

BMesh is the new mesh editing API, used for efficient manipulation of mesh data.

Each entity in a mesh has an associated persistent bitfield that stores flags.

Entities

Faces

Faces link to a loop in the loop cycle, the circular linked list of loops defining the boundary of the face.

Edges

Edges represent a connection between two vertices, but also store a link to a loop in the radial cycle of the edge.

Vertices

Vertices store a coordinate and link to an edge in the disk cycle of the vertex.

Loops

They define the boundary loop of a face. Each loop corresponds to an edge. pic1 pic2

Cycles

Loops store the pointers:

• v - pointer to the first vertex
• e - pointer to the loop's edge
• f - pointer to the face associated with this loop
