Detailed Description
A node in the imported hierarchy.
Each node has name, a parent node (except for the root node), a transformation relative to its parent and possibly several child nodes. Simple file formats don't support hierarchical structures - for these formats the imported scene does consist of only a single root node without children.
Member Data Documentation
◆ mChildren
| C_STRUCT aiNode** aiNode::mChildren |
The child nodes of this node.
NULL if mNumChildren is 0.
◆ mMeshes
| unsigned int* aiNode::mMeshes |
The meshes of this node.
Each entry is an index into the mesh list of the aiScene.
◆ mMetaData
| C_STRUCT aiMetadata* aiNode::mMetaData |
Metadata associated with this node or NULL if there is no metadata.
Whether any metadata is generated depends on the source file format. See the importer_notes page for more information on every source file format. Importers that don't document any metadata don't write any.
◆ mName
| C_STRUCT aiString aiNode::mName |
The name of the node.
The name might be empty (length of zero) but all nodes which need to be referenced by either bones or animations are named. Multiple nodes may have the same name, except for nodes which are referenced by bones (see aiBone and aiMesh::mBones). Their names must be unique.
Cameras and lights reference a specific node by name - if there are multiple nodes with this name, they are assigned to each of them.
There are no limitations with regard to the characters contained in the name string as it is usually taken directly from the source file.
Implementations should be able to handle tokens such as whitespace, tabs, line feeds, quotation marks, ampersands etc.
Sometimes assimp introduces new nodes not present in the source file into the hierarchy (usually out of necessity because sometimes the source hierarchy format is simply not compatible). Their names are surrounded by
<>
e.g.
<DummyRootNode>
.
◆ mNumChildren
| unsigned int aiNode::mNumChildren |
The number of child nodes of this node.
◆ mNumMeshes
| unsigned int aiNode::mNumMeshes |
The number of meshes of this node.
◆ mParent
| C_STRUCT aiNode* aiNode::mParent |
Parent node.
NULL if this node is the root node.
◆ mTransformation
| C_STRUCT aiMatrix4x4 aiNode::mTransformation |
The transformation relative to the node's parent.
