Implementation4.6. Implementation of Data Consumers4.6.3 SoRenderNodeFigure 4.21: CashFlow data flow model: Render nodeThis node can handel several input streams. The major difference in comparisonto the SoCfMapperNode and SoCfLoaderNode is, that it creates only OpenGL calls.SoRenderNode - File FormatThis SoPointRenderNode only needs a unique key pointing to a SoDataAccessNode,since the topology of a point cloud is not relevant in this example. In figure 3.8 onpage 48 several SoPointRenderNodes are used in combination with variousSoDataAccessNodes.SoPointRenderNode iv–file#Inventor V2.0 asciiSoPointRenderNode {fields [SoSFString dataAccess_Key ]}dataAccess_Key [ "my_unique_DataAccessKey" ]# points to SoDataAccessNode## value: absolute key ( any string )# or relative key @( integer )CashFlow iv–file96
