Detailed Description

Base implementation of a system to procedurally compute values based on scene description and computation definitions.

ExecSystem owns all the structures necessary to compile, schedule and evaluate requested computation values. Derived classes are responsible for interfacing with the underlying scene description.

Constructor & Destructor Documentation

ExecSystem()

EXEC_API ExecSystem ( EsfStage &&  stage )

explicitprotected

Construct an exec system for computing values on stage.

Member Function Documentation

_ChangeTime()

EXEC_API void _ChangeTime ( const EfTime &  time )

protected

Changes time on the system.

This stores the new time value in the time input node output, invalidates all time dependent computed values, and notifies requests of the change in time.

_Compute()

EXEC_API void _Compute ( const VdfSchedule &  schedule, const VdfRequest &  computeRequest  )

protected

Computes the values in the computeRequest using the provided schedule.

_ParallelForEachRequest()

EXEC_API void _ParallelForEachRequest ( TfFunctionRef< void(Exec_RequestImpl &)>  f ) const

protected

Invoke f on each outstanding exec request.

f is executed with the request tracker mutex held so it must not re-enter the request tracker. This method may execute f for multiple requests concurrently.
