List of all members. Scalar data is represented by a subclass of vtkDataArray , and may be any any type of data, although generic operations on scalar data is performed using floating point values.
Scalars typically provide a single value per point.
However, there are types of scalars that have multiple values or components. In this case, the ActiveComponent instance variable is used to indicate which component value is to be used for scalar data. Because of the close relationship between scalars and colors, scalars also maintain an internal lookup table. If provided, this table is used to map scalars into colors, rather than the lookup table that the vtkMapper objects are associated with. Generally used to create one when none is available.
