GetDataAtPreviousF rameNode

Introduced

7.0

UI Location

• Data Access

Description

Accesses data in previous frame state on elements in the scene specified by the reference string. The fact that the accessed data is evaluated on the previous frame is the main difference with the GetDataNode node.

Such a node is specially useful to interpolate values in order to approximate values for any fraction of the current frame, in order to minimize frame rounding artifacts.

Like the GetDataNode, you can build the path to the data you want to fetch by daisy chaining Get Data nodes.

Port Description

Inputs

Group ID | Instance s | Port Name | Connection Info | Description
0 | 1 | source | • Type: siICENodeDataAny • Structure: siICENodeStructureAny • Context: siICENodeContextAny | Location at which to get the attribute requested. Only required when getting geometry attributes at a specified location. Otherwise, geometry attributes are retrieved from the current subcomponent (point, edge, or polygon) being processed.
1 | 1 | inname | • Type: siICENodeDataReference • Structure: siICENodeStructureSingle • Context: siICENodeContextSingleton | Allows daisy chaining Get Data nodes. The scene path received in this port is appended as a prefix to the reference string of the node.

Outputs

Port Name | Connection Info | Description
value | • Type: siICENodeDataAny • Structure: siICENodeStructureAny • Context: siICENodeContextAny | The value of the data being accessed. The type, structure and context of this port automatically maps to the type, structure and context of the data accessed.
outname | • Type: siICENodeDataReference • Structure: siICENodeStructureSingle • Context: siICENodeContextSingleton | Allows daisy chaining Get Data nodes. Connect this port into the In Name port of another Get Data to prefix the reference of the other node with the reference of this node.
