| Types of dependency graph data. More... | |
Mesh function set for dependency node data.
MFnMeshData allows the creation and manipulation of Mesh data objects for use in the dependency graph.
If a user written dependency node either accepts or produces Meshes, then this class is used to create data blocks into which Meshes can be constructed before being passed to other dependency graph nodes. The MDataHandle::type method will return kMesh when data of this type is present.
If a node is receiving a Mesh via an input attribute, the asMesh method of MDataHandle can be used to access that input Mesh.
If a node is to create a Mesh and send it via an output attribute, a new MFnMeshData must be instantiated and then the create method called to build the actual data block as an MObject. This MObject should be passed to the MFnMesh::create method as the parentOrOwner parameter so that the Mesh will be constructed inside the data block. The MDataHandle::set routine is then used to pass the data block down the connection.
