cisstStereoVision svlFilterBase

svlFilterBase class

Every filter of the cisstStereoVision library is derived from the baseclass svlFilterBase.

Name	Description
default constructor	Typically, input and output connectors and their supported sample types are added in the default constructor.
`int Initialize(svlSample * syncInput, svlSample * syncOutput)`	Input sample prototype for the synchronous input is stored in `syncInput`. If the filter has outputs, the `Initialize` method is responsible for providing sample prototypes for the filters that may be connected to them. The sample prototype for the synchronous output needs to be passed along in `syncOutput`. Sample prototypes for the asynchronous outputs need to be pushed to the corresponding outputs.
`int Process(svlProcInfo * procInfo, svlSample * syncInput, svlSample * syncOutput)`	The synchronous input sample is stored in `syncInput`. If the filter has outputs, the synchronous output sample needs to be passed along in `syncOutput`. Samples for the asynchronous outputs may be pushed to the corresponding outputs.
