ObjectMeshStatic Class

Members

static ObjectMeshStaticPtr create(const Ptr<Mesh> & mesh)

ObjectMeshStatic constructor. Creates a new mesh object from a given file.

Arguments

const Ptr<Mesh> & mesh - A mesh smart pointer.

static ObjectMeshStaticPtr create(const char * name, int unique = 0)

ObjectMeshStatic constructor. Creates a new mesh object from a given file.

Arguments

const char * name - Path to the mesh file.
int unique - When you create several objects out of a single .mesh file, the instance of the mesh geometry is created. If you then change the source geometry, its instances will be changed as well. To avoid this, set the unique flag to 1, so a copy of the mesh geometry will be created and changes won't be applied.
