Remarks
Evaluate this template over the given swept range, adding any execution tokens to the specified list.
Only called when the containing template has an evaluation method of EEvaluationMethod::Swept This function should perform any expensive or costly evaluation logic required to calculate the final animated state. Potentially called on a thread, and as such has no access to the current evaluation environment.
Parameters
| Name | Description |
|---|---|
| Operand | Unique handle to the operand on which we are to operate. Only to be used as a reference, or forwarded throgh to an execution token. |
| Context | Evaluation context specifying the current evaluation time, sub sequence transform and other relevant information. |
| SweptRange | The range this is to be swept in this evaluation - always fully contained by the context's range |
| PersistentData | Persistent data store which can be used to access arbitrary data pertaining to the current template that should have been set up in initialize. |
| ExecutionTokens | Stack of execution tokens that will be used to apply animated state to the environment at a later time. |
