Perform evaluation on the specified segment of the track. Will generally call Evaluate on all child templates in the current segment as well. @note 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. Only called if EnableOverrides(CustomEvaluateFlag) has been called (see SetupOverrides).
Parameter |
Description |
---|---|
Track |
The parent evaluation track that has knowledge of all child tracks and segments |
SegmentID |
The identifier of the segment at the current time |
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. |
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. |
