Vertex property node.
This property node is be used to efficiently specify coordinates, normals, tangents, texture coordinates, colors, transparency values, material binding, normal and tangent binding for vertex-based shapes, i.e., shapes derived from SoVertexShape.
An SoVertexProperty node can be used as a child of a group node in a scene graph, in which case the properties it specifies are inherited by subsequent shape nodes in the graph. It can also be directly referenced using the vertexProperty field of a vertex-based shape, bypassing scene graph inheritance. Direct referencing is the recommended practice.
When directly referenced by a VertexProperty field of a vertex-based shape, the SoVertexProperty node is the most efficient way of specifying vertex-based shapes. Use of the directly referenced SoVertexProperty node results in significantly faster scene rendering than scene graph inheritance of vertex properties, provided all required vertex properties are specified in the SoVertexProperty node.
Because the class SoVertexProperty is derived from SoNode, a vertex property node can be inserted as a child node in a scene graph. When inserted as a node in a scene graph, the SoVertexProperty node is traversed as any other property node and the properties it specifies are inherited by subsequent shape nodes in the scene graph. It specifies the current material, normal and tangent bindings, and can be used to specify the current 3D coordinates, the current normals, the current tangents, the current texture coordinates, the current diffuse colors, and the current transparencies.
All multiple-valued fields in the SoVertexProperty node are optional. If a field is not present (i.e. if it has 0 values), then shapes that require the missing information are required to obtain it from the current traversal state. However, developers are cautioned that, for optimal performance, the vertex property node should be referenced as the VertexProperty field of an SoVertexShape, and should specify in its fields all values required to render that shape.
