(Inherited from SoDisposable.) | |

Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) | |
FieldsAreEqual | Returns true if this object's fields are exactly equal to fc's fields. | |
Get | Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string. | |
GetAllFields | Returns a list of fields, including the eventIn's and eventOut's. | |
GetAlternateRep | This method is called by actions to allow the node to provide an "alternate representation" when appropriate (typically depending on the action type). | |

GetFields | Appends references to all of this object's fields to resultList, and returns the number of fields appended. | |
GetHashCode |
Overrides GetHashCode().
(Inherited from SoNetBase.) | |
GetMatrix | (Inherited from SoNode.) | |
GetName | Returns the name of an instance. | |
GetPredefinedParameterName | Returns the predefined instance parameter name for the specified paramKey. | |

HandleEvent | (Inherited from SoNode.) | |
HasDefaultValues | Returns true if all of the object's fields have their default values. | |
IsBoundingBoxIgnoring | This method is used by getBoundingBox action traversal to know if the current node must be traversed or not, ie the bounding should be ignored. | |
IsNotifyEnabled | Notification is the process of telling interested objects that this object has changed. | |
IsOverride | Returns the state of the override flag. | |
IsSynchronizable | Gets the ScaleViz synchronizable state of this object. | |
Pick | (Inherited from SoNode.) | |
RayPick | (Inherited from SoNode.) | |
Search | (Inherited from SoNode.) | |
Set | Sets one or more fields in this object to the values specified in the given string, which should be a string in the Open Inventor file format. | |
SetName | (Inherited from SoBase.) | |
SetOverride | Turns the override flag on or off. | |
SetPredefinedParameterName | Sets the name field to the string corresponding to the given paramKey. | |
SetSynchronizable | Sets this to be a ScaleViz synchronizable object. | |
SetToDefaults | Sets all fields in this object to their default values. | |
ToString |
Converts this SoBase structure to a human readable string.
(Inherited from SoBase.) | |
Touch | Marks an instance as modified, simulating a change to it. | |
Write | (Inherited from SoNode.) |
Name | Description | |
---|---|---|
components | Specifies the number of components per generic vertex parameter. | |
divisor | This field modifies the rate at which values advance during multiple instance rendering. | |
identifier | Specifies the parameter's integer name which is declared and used within low-level shading programs. | |
IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) | |
name | Specifies the parameter's string name which is declared and used within high-level shading programs. | |
offset | Offset in bytes to the first parameter within the buffer. | |
shouldBeNormalized | Specifies if the fixed-point data in the buffer object should be normalized when they are accessed. | |
stride | Specifies the byte offset between consecutive generic vertex parameter. | |
type | Specifies the data type from the class OIV.Inventor.SbDataType of each generic vertex parameter component. | |
UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) | |
value | Specifies the parameter's values. |
This node allows the application to provide a per-instance parameter of any type, using an OIV.Inventor.Devices.SoBufferObject. It is used with the OIV.Inventor.Nodes.SoMultipleInstance node.
Some predefined parameter names can be used for common instance parameters like position, rotation and scale factor. Parameter objects with these names are automatically managed and are recognized and used by the default shaders. Applications can define additional parameter objects to be used by custom shaders.
See the base classes OIV.Inventor.Nodes.SoShaderParameter, OIV.Inventor.Nodes.SoVertexShaderParameter and OIV.Inventor.Nodes.SoVertexShaderParameterBufferObject for more details.
Note: Unlike OIV.Inventor.Nodes.SoVertexShaderParameter, instances of this node must be added to the parameters field of an OIV.Inventor.Nodes.SoMultipleInstance node, not directly in the scene graph.
