Detailed Description

draw vtkPolyData onto the image plane

vtkPolyDataMapper2D is a mapper that renders 3D polygonal data (vtkPolyData) onto the 2D image plane (i.e., the renderer's viewport). By default, the 3D data is transformed into 2D data by ignoring the z-coordinate of the 3D points in vtkPolyData, and taking the x-y values as local display values (i.e., pixel coordinates). Alternatively, you can provide a vtkCoordinate object that will transform the data into local display coordinates (use the vtkCoordinate::SetCoordinateSystem() methods to indicate which coordinate system you are transforming the data from).

virtual void vtkPolyDataMapper2D::CreateDefaultLookupTable  )  [virtual]
 

Create default lookup table. Generally used to create one when none is available with the scalar data.

virtual void vtkPolyDataMapper2D::SetScalarVisibility int   )  [virtual]
 

Turn on/off flag to control whether scalar data is used to color objects.

Setting ColorModeToMapScalars means that all scalar data will be mapped through the lookup table. (Note that for multi-component scalars, the particular component to use for mapping can be specified using the ColorByArrayComponent() method.)

virtual void vtkPolyDataMapper2D::SetUseLookupTableScalarRange int   )  [virtual]
 

Control whether the mapper sets the lookuptable range based on its own ScalarRange, or whether it will use the LookupTable ScalarRange regardless of it's own setting. By default the Mapper is allowed to set the LookupTable range, but users who are sharing LookupTables between mappers/actors will probably wish to force the mapper to use the LookupTable unchanged.

virtual int vtkPolyDataMapper2D::GetUseLookupTableScalarRange  )  [virtual]
 

Control whether the mapper sets the lookuptable range based on its own ScalarRange, or whether it will use the LookupTable ScalarRange regardless of it's own setting.

virtual void vtkPolyDataMapper2D::SetScalarMode int   )  [virtual]
 

Control how the filter works with scalar point data and cell attribute data. By default (ScalarModeToDefault), the filter will use point data, and if no point data is available, then cell data is used.

You can also choose to get the scalars from an array in point field data (ScalarModeToUsePointFieldData) or cell field data (ScalarModeToUseCellFieldData). If scalars are coming from a field data array, you must call ColorByArrayComponent before you call GetColors.

Reimplemented from vtkAbstractMapper.

virtual void vtkPolyDataMapper2D::SetTransformCoordinate vtkCoordinate  )  [virtual]

vtkUnsignedCharArray* vtkPolyDataMapper2D::MapScalars double  alpha  ) 
 

Map the scalars (if there are any scalars and ScalarVisibility is on) through the lookup table, returning an unsigned char RGBA array. This is typically done as part of the rendering process.
