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.

Casts an ObjectMeshStatic out of the Object instance.

Arguments

const Ptr<Object> & base - Pointer to Object.

Return value

Pointer to ObjectMeshStatic.

Casts an ObjectMeshStatic out of the Node instance.

Arguments

const Ptr<Node> & node - Pointer to Node.

Return value

Pointer to ObjectMeshStatic.

int getMesh(const Ptr<Mesh> & mesh)

Copies the current mesh into the source mesh. For example, you can obtain geometry of the static mesh and then change it:

Source code (C++)

// a static mesh from which geometry will be obtained
ObjectMeshStaticPtr staticMesh = ObjectMeshStatic::create("box.mesh");
// create a new mesh
MeshPtr mesh = Mesh::create();
// copy geometry to the created mesh
if (staticMesh->getMesh(mesh)) {
	// do something with the obtained mesh
}
else {
	Log::error("Failed to copy a mesh\n");
}

Arguments

const Ptr<Mesh> & mesh - The source mesh.

Return value

1 if the mesh is copied successfully; otherwise, 0.

int setMesh(const Ptr<Mesh> & mesh, int unique = 1)

Copies a given source mesh into the current mesh. For example, you can copy a mesh into another one as follows:

Source code (C++)

// create ObjectMeshStatic instances 
ObjectMeshStaticPtr staticMesh = ObjectMeshStatic::create("box.mesh");
ObjectMeshStaticPtr staticMesh_2 = ObjectMeshStatic::create("capsule.mesh");

// create a Mesh instance
MeshPtr firstMesh = Mesh::create();

// get the mesh of the ObjectMeshStatic and copy it to the Mesh class instance
staticMesh->getMesh(firstMesh);

// put the firstMesh mesh to the staticMesh_2 instance
staticMesh_2->setMesh(firstMesh);

Arguments

const Ptr<Mesh> & mesh - Source mesh to be copied.
int unique - Unique flag used when you create several objects out of a single Mesh instance :
- 0 - An instance of source mesh geometry is created. If the source geometry is changed at runtime, its instances will be changed as well.

Return value

1 if the mesh is copied successfully; otherwise, 0.

void setMeshName(const char * name, int force_load = 0)
