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 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.)

Create default lookup table.

virtual void vtkMapper::SetStatic ( vtkTypeBool  )
virtual

Turn on/off flag to control whether the mapper's data is static.

Static data means that the mapper does not propagate updates down the pipeline, greatly decreasing the time it takes to update many mappers. This should only be used if the data never changes.

◆ SetColorMode()

virtual void vtkMapper::SetColorMode ( int  )
virtual

default (ColorModeToDefault), unsigned char scalars are treated as colors, and NOT mapped through the lookup table, while everything else is.

ColorModeToDirectScalar extends ColorModeToDefault such that all integer types are treated as colors with values in the range 0-255 and floating types are treated as colors with values in the range 0.0-1.0. 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 SelectColorArray() method.)

◆ SetInterpolateScalarsBeforeMapping()

By default, vertex color is used to map colors to a surface.

Colors are interpolated after being mapped. This option avoids color interpolation by using a one dimensional texture map for the colors.

virtual void vtkMapper::SetUseLookupTableScalarRange ( vtkTypeBool  )
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.

◆ SetScalarMode()

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.

◆ SetResolveCoincidentTopology()

static void vtkMapper::SetResolveCoincidentTopology ( int  val)
static

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, lines and points from each other. ShiftZBuffer is a legacy method that used to remap the z-buffer to distinguish vertices, lines, and polygons, but does not always produce acceptable results. You should only use the PolygonOffset method (or none) at this point.

Map the scalars (if there are any scalars and ScalarVisibility is on) through the lookup table, returning an unsigned char RGBA array.

virtual int vtkMapper::CanUseTextureMapForColoring ( vtkDataObject input)

Returns if we can use texture maps for scalar coloring.

Note this doesn't say we "will" use scalar coloring. It says, if we do use scalar coloring, we will use a texture. When rendering multiblock datasets, if any 2 blocks provide different lookup tables for the scalars, then also we cannot use textures. This case can be handled if required.

Reimplemented in vtkCompositeMapperHelper2.
