Detailed Description

abstract class specifies interface to map data to graphics primitives

vtkMapper is an abstract class to specify interface between data and graphics primitives. Subclasses of vtkMapper map data through a lookuptable and control the creation of rendering primitives that interface to the graphics library. The mapping can be controlled by supplying a lookup table and specifying a scalar range to map data through.

There are several important control mechanisms affecting the behavior of this object. The ScalarVisibility flag controls whether scalar data (if any) controls the color of the associated actor(s) that refer to the mapper. The ScalarMode ivar is used to determine whether scalar point data or cell data is used to color the object. By default, point data scalars are used unless there are none, in which cell scalars are used. Or you can explicitly control whether to use point or cell scalar data. Finally, the mapping of scalars through the lookup table varies depending on the setting of the ColorMode flag. See the documentation for the appropriate methods for an explanation.

Another important feature of this class is whether to use immediate mode rendering (ImmediateModeRenderingOn) or display list rendering (ImmediateModeRenderingOff). If display lists are used, a data structure is constructed (generally in the rendering library) which can then be rapidly traversed and rendered by the rendering library. The disadvantage of display lists is that they require additionally memory which may affect the performance of the system.

Another important feature of the mapper is the ability to shift the z-buffer to resolve coincident topology. For example, if you'd like to draw a mesh with some edges a different color, and the edges lie on the mesh, this feature can be useful to get nice looking lines. (See the ResolveCoincidentTopology-related methods.)

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 vtkMapper::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. Alternatively you can explicitly set the filter to use point data (ScalarModeToUsePointData) or cell data (ScalarModeToUseCellData). 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 SelectColorArray before you call GetColors. When ScalarMode is set to use Field Data (ScalarModeToFieldData), you must call SelectColorArray to choose the field data array to be used to color cells. In this mode, if the poly data has triangle strips, the field data is treated as the celldata for each mini-cell formed by a triangle in the strip rather than the entire strip.

Set/Get a global flag that controls whether coincident topology (e.g., a line on top of a polygon) is shifted to avoid z-buffer resolution (and hence rendering problems). If not off, there are two methods to choose from. PolygonOffset uses graphics systems calls to shift polygons, but does not distinguish vertices and lines from one another. ShiftZBuffer remaps the z-buffer to distinguish vertices, lines, and polygons, but does not always produce acceptable results. If you use the ShiftZBuffer approach, you may also want to set the ResolveCoincidentTopologyZShift value. (Note: not all mappers/graphics systems implement this functionality.)

Used to set the polygon offset scale factor and units. Used when ResolveCoincidentTopology is set to PolygonOffset. These are global variables.

double &  units
[static]
 

Used to set the polygon offset scale factor and units. Used when ResolveCoincidentTopology is set to PolygonOffset. These are global variables.

static void vtkMapper::SetResolveCoincidentTopologyZShift double  val  )  [static]
 

Used to set the z-shift if ResolveCoincidentTopology is set to ShiftZBuffer. This is a global variable.

static double vtkMapper::GetResolveCoincidentTopologyZShift  )  [static]
 

Used to set the z-shift if ResolveCoincidentTopology is set to ShiftZBuffer. This is a global variable.

virtual double* vtkMapper::GetBounds  )  [virtual]
 

Return bounding box (array of six doubles) of data expressed as (xmin,xmax, ymin,ymax, zmin,zmax).

Implements vtkAbstractMapper3D.

Reimplemented in vtkHierarchicalPolyDataMapper, and vtkPolyDataMapper.

virtual void vtkMapper::GetBounds double  bounds[6]  )  [inline, virtual]
 

Return bounding box (array of six doubles) of data expressed as (xmin,xmax, ymin,ymax, zmin,zmax).

Reimplemented from vtkAbstractMapper3D.

Reimplemented in vtkHierarchicalPolyDataMapper, and vtkPolyDataMapper.

Definition at line 309 of file vtkMapper.h.

References vtkAbstractMapper3D::GetBounds().

void vtkMapper::SetRenderTime double  time  )  [inline]
 

This instance variable is used by vtkLODActor to determine which mapper to use. It is an estimate of the time necessary to render. Setting the render time does not modify the mapper.

Definition at line 317 of file vtkMapper.h.

virtual double vtkMapper::GetRenderTime  )  [virtual]
 

This instance variable is used by vtkLODActor to determine which mapper to use. It is an estimate of the time necessary to render. Setting the render time does not modify the mapper.

vtkDataSet* vtkMapper::GetInput  ) 
 

Get the input as a vtkDataSet. This method is overridden in the specialized mapper classes to return more specific data types.

Reimplemented in vtkDataSetMapper, and vtkPolyDataMapper.

vtkDataSet* vtkMapper::GetInputAsDataSet  )  [inline]
 

Get the input to this mapper as a vtkDataSet, instead of as a more specialized data type that the subclass may return from GetInput(). This method is provided for use in the wrapper languages, C++ programmers should use GetInput() instead.

vtkUnsignedCharArray* vtkMapper::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. The alpha parameter allows the blending of the scalars with an additional alpha (typically which comes from a vtkActor, etc.)

virtual void vtkMapper::SetScalarMaterialMode int   )  [virtual]
 

Set/Get the light-model color mode.

virtual int vtkMapper::GetScalarMaterialMode  )  [virtual]
 

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. The alpha parameter allows the blending of the scalars with an additional alpha (typically which comes from a vtkActor, etc.)

void vtkMapper::SetScalarMaterialModeToDefault  )  [inline]
 

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. The alpha parameter allows the blending of the scalars with an additional alpha (typically which comes from a vtkActor, etc.)

void vtkMapper::SetScalarMaterialModeToAmbient  )  [inline]
 

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. The alpha parameter allows the blending of the scalars with an additional alpha (typically which comes from a vtkActor, etc.)

void vtkMapper::SetScalarMaterialModeToDiffuse  )  [inline]
 

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. The alpha parameter allows the blending of the scalars with an additional alpha (typically which comes from a vtkActor, etc.)
