Remarks

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 OIV.Inventor.Nodes.SoVertexShape.

An OIV.Inventor.Nodes.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 OIV.Inventor.Nodes.SoVertexProperty node is the most efficient way of specifying vertex-based shapes. Use of the directly referenced OIV.Inventor.Nodes.SoVertexProperty node results in significantly faster scene rendering than scene graph inheritance of vertex properties, provided all required vertex properties are specified in the OIV.Inventor.Nodes.SoVertexProperty node.

Because the class OIV.Inventor.Nodes.SoVertexProperty is derived from OIV.Inventor.Nodes.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 OIV.Inventor.Nodes.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 OIV.Inventor.Nodes.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 OIV.Inventor.Nodes.SoVertexShape, and should specify in its fields all values required to render that shape.

Fields:

The various fields in a vertex property node can be used in place of corresponding fields in other property nodes, as follows:

If one of these nodes appears higher in the scene graph and setOverride(true) was called on that node, those values are used instead of the corresponding field of the vertex property node. Note: Calling setIgnored(true) on the fields of this node has no effect on its behavior.

Color:

If OIV.Inventor.Nodes.SoVertexProperty.SetOverride(System.Boolean) was called on an OIV.Inventor.Nodes.SoMaterial node higher in the scene graph and either the diffuseColor field or the transparency field is not ignored (setIgnored()), then the color and transparency values from the OIV.Inventor.Nodes.SoMaterial node are used instead of the values in the OIV.Inventor.Nodes.SoVertexProperty. It is not currently possible to override just the color or just the transparency.

Transparency:

The default transparency algorithm is NO_SORT. To get a nice appearance for transparent objects you must change this to another value, for example, OPAQUE_FIRST or SORTED_PIXEL, using the setTransparencyType method in the viewer or renderAction class. See OIV.Inventor.Actions.SoGLRenderAction for a discussion of transparency algorithms and rendering order.

Material binding:

The OIV.Inventor.Nodes.SoVertexProperty.materialBinding field replaces the value field of the OIV.Inventor.Nodes.SoMaterialBinding node. The OIV.Inventor.Nodes.SoVertexProperty.materialBinding field in a directly referenced OIV.Inventor.Nodes.SoVertexProperty node has no effect unless there is a nonempty OIV.Inventor.Nodes.SoVertexProperty.orderedRGBA field, in which case the material binding specifies the assignment of diffuse colors and alpha values to the shape.

Normal binding:

The OIV.Inventor.Nodes.SoVertexProperty.normalBinding field replaces the value field of the OIV.Inventor.Nodes.SoNormalBinding node. The OIV.Inventor.Nodes.SoVertexProperty.normalBinding field of a directly referenced OIV.Inventor.Nodes.SoVertexProperty node has no effect unless there is a nonempty OIV.Inventor.Nodes.SoVertexProperty.normal field, in which case the normal binding specifies the assignment of normal vectors to the shape.

Tangent binding:

The OIV.Inventor.Nodes.SoVertexProperty.tangentBinding field of a directly referenced OIV.Inventor.Nodes.SoVertexProperty node has no effect unless there is a nonempty OIV.Inventor.Nodes.SoVertexProperty.tangent field, in which case the tangent binding specifies the assignment of tangent vectors to the shape.

ACTION BEHAVIOR

OIV.Inventor.Actions.SoGLRenderAction, OIV.Inventor.Actions.SoCallbackAction, OIV.Inventor.Actions.SoPickAction When traversed in a scene graph, sets coordinates, normals, tangents, texture coordinates, diffuse colors, transparency, normal binding, tangent 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 tangentBinding field has no effect if there are no tangents. The materialBinding has no effect if there are no packed colors. Sets: OIV.Inventor.Elements.SoCoordinateElement, OIV.Inventor.Elements.SoNormalElement, OIV.Inventor.Elements.SoNormalBindingElement, OIV.Inventor.Elements.SoMaterialElementOIV.Inventor.Elements.SoMaterialBindingElement, OIV.Inventor.Elements.SoTextureCoordinateElement, OIV.Inventor.Elements.SoTangentElement, OIV.Inventor.Elements.SoTangentBindingElement

OIV.Inventor.Actions.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. Sets: OIV.Inventor.Elements.SoCoordinateElement
