ProcNode Class Reference

#include "steam/engine/procnode.hpp"

Description

Key abstraction of the Render Engine: A Data processing Node.

Todo:

it's not clear as of 9/09 if ProcNode shall be an ABC/Interface It might be used as ABC (as was the original intention) when implementing several query/information functions. In that case, the ctor will become protected. The alternative would be to push down these information-retrieval part into a configurable element within WiringDescriptor, in which case we even might drop ProcNode as a frontend entirely.

Member Function Documentation

pull()

BuffHandle pull ( State &  currentProcess, uint  requestedOutputNr = 0  ) const

inline

Engine Core operation: render and pull output from this node.

On return, currentProcess will hold onto output buffer(s) containing the calculated result frames. In case this node calculates a multichannel output, only one channel can be retrieved by such a pull() call, but you can expect data of the other channels to be processed and fed to cache.

Parameters

currentProcess	the current processing state for managing buffers and accessing current parameter values
requestedOutputNr	the output channel requested (in case this node delivers more than one output channel)

Returns

handle to the buffer containing the calculated result.
