RenderDrive Class Reference

#include "steam/engine/render-drive.hpp"

Description

The active drive to keep the render process going – implemented as a job planning job, that repeatedly triggers itself again for the next planning chunk.

The RenderDrive is created and owned by the corresponding CalcStream, and operates the job planning pipeline, backed by the dispatcher.

Member Function Documentation

invokeJobOperation()

void invokeJobOperation ( JobParameter  parameter )

overrideprivate

entry point (interface JobClosure): invoke the concrete job operation.

In this case, the job operation is responsible for planning a chunk of actual render jobs.

Definition at line 46 of file render-drive.cpp.

prepareRenderPlanningFrom()

Job prepareRenderPlanningFrom

(

FrameCnt

startFrame

)

create the "start trigger job" Scheduling this job will effectively get a calculation stream into active processing, since it causes the first chunk of job planning plus the automated scheduling of follow-up planning jobs.

The relation to real (wall clock) time will be established when the returned job is actually invoked

Parameters

startFrame

where to begin rendering, relative to the nominal time grid implicitly given by the ModelPort to be pulled
