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 as the **VertexProperty** **SoSFField** of a vertex-based shape, bypassing scene graph inheritance. When directly referenced by a **VertexProperty** **SoSFField** 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 and normal bindings, and can be used to specify the current 3D coordinates, the current normals, 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, users 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. The various fields in a vertex property node can be used in place of corresponding fields in other property nodes, as follows: The **vertex** field contains 3D coordinates, as in the **point** field of an **SoCoordinate3** node. The **normal** field contains normal vectors, as in the **vector** field of the **SoNormal** node. The **orderedRGBA** field contains packed colors in the hexadecimal format **0xrrggbbaa**, where **rr** is the red value (between 00 and 0xFF hex) **gg** is the green value (between 00 and 0xFF hex) **bb** is the blue value (between 00 and 0xFF hex) **aa** is the alpha value (between 00 = transparent and 0xFF = opaque). The packed colors are equivalent to an **SoPackedColor** node, and provide values for both diffuse color and transparency. The **texCoord** field replaces the **point** field of the **SoTextureCoordinate2** node. If the transparency type is **SoGLRenderAction::SCREEN\_DOOR**, only the first transparency value will be used. With other transparency types, multiple transparencies will be used. The **materialBinding** field replaces the **value** field of the **SoMaterialBinding** node. The **materialBinding** field in a directly referenced **SoVertexProperty** node has no effect unless there is a nonempty **orderedRGBA** field, in which case the material binding specifies the assignment of diffuse colors and alpha values to the shape. The **materialBinding** field can take as value any of the material bindings supported by Inventor. The **normalBinding** field replaces the **value** field of the **SoNormalBinding** node. The **normalBinding** field of a directly referenced **SoVertexProperty** node has no effect unless there is a nonempty **normal** field, in which case the normal binding specifies the assignment of normal vectors to the shape. The value of the **normalBinding** field can be any of the normal bindings supported by Inventor. ## FIELDS **SoMFVec3f** **vertex**\ vertex coordinate(s). **SoMFVec3f** **normal**\ normal vector(s). **SoMFUInt32** **orderedRGBA**\ packed color(s), including transparencies. **SoMFVec2f** **texCoord**\ texture coordinate(s). **SoSFEnum** **normalBinding**\ normal binding. **SoSFEnum** **materialBinding**\ material binding. ## METHODS **SoVertexProperty()**\ Creates an SoVertexProperty node with default settings. ## ACTION BEHAVIOR **SoGLRenderAction, SoCallbackAction, SoPickAction**\ When traversed in a scene graph, sets coordinates, normals, texture coordinates, diffuse colors, transparency, normal binding and material binding in current traversal state. If not traversed, has no effect on current traversal state associated with action. The normalBinding field has no effect if there are no normals. The materialBinding has no effect if there are no packed colors. **SoGetBoundingBoxAction**\ When traversed in a scene graph, sets coordinates in current traversal state. If not traversed, has no effect on current traversal state associated with action. ## FILE FORMAT/DEFAULTS ``` VertexProperty { vertex [ ] normal [ ] texCoord [ ] orderedRGBA [ ] materialBinding OVERALL normalBinding PER_VERTEX_INDEXED } ``` ## SEE ALSO **SoIndexedTriangleStripSet SoIndexedFaceSet SoIndexedLineSet SoTriangleStripSet SoLineSet SoFaceSet SoPointSet SoQuadMesh SoVertexShape SoIndexedShape SoNonindexedShape**
