ExportGraphicsMeshVisitor Class

  • Iterator to walk the facets of an ExportGraphicsMesh and present them to the world as if visiting a Polyface.
  • Because the ExportGraphicsMesh has limited data:
    • There is no auxData in this visitor.
    • There is no color in this visitor.
    • All edgeVisible are true.

Methods

Name Description
clearArrays(): void clear the contents of all arrays.  
clientAuxIndex(_i: number): number Return the aux data index of vertex i within the currently loaded facet  
clientColorIndex(_i: number): number Return the color index of vertex i within the currently loaded facet  
clientNormalIndex(i: number): number Return the normal index of vertex i within the currently loaded facet.  
clientParamIndex(i: number): number Return the param index of vertex i within the currently loaded facet.  
clientPointIndex(i: number): number Return the point index of vertex i within the currently loaded facet  
clientPolyface(): Polyface return the client polyface  
currentReadIndex(): number Return the index (in the client polyface) of the current facet  
moveToNextFacet(): boolean Load data for the next facet.  
moveToReadIndex(facetIndex: number): boolean Select a facet by simple index.  
pushDataFrom(other: PolyfaceVisitor, index: number): void transfer data from a specified index of the other visitor as new data in this visitor.  
pushInterpolatedDataFrom(other: PolyfaceVisitor, index0: number, fraction: number, index1: number): void transfer interpolated data from the other visitor.  
reset(): void Reset the iterator to start at the first facet of the polyface.  
setNumWrap(numWrap: number): void Set the number of vertices to replicate in visitor arrays.  
create(polyface: ExportGraphicsMesh, numWrap: number): ExportGraphicsMeshVisitor Static Create a visitor for iterating the facets of polyface, with indicated number of points to be added to each facet to produce closed point arrays
