Method append

splashsurf_lib/src/mesh.rs:762–780

Appends the other mesh to this mesh This operation appends the content of the other mesh's vertex and triangle storage tho this mesh. The vertex indices of the appended triangles are adjusted accordingly. The other mesh will be empty after this operation.
