[vtkusers] vtkMapper, ColorMode Default

[Henry Lehmann]

Hello,

i am trying to understand the color mapping of vtkMapper and i am 
reading the doxygen.
It is stated:

Control how the scalar data is mapped to colors. By default 
(ColorModeToDefault), unsigned char scalars are treated as colors, and 
NOT mapped through the lookup table, while everything else is. 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 
theSelectColorArray() 
<http://www.vtk.org/doc/nightly/html/classvtkMapper.html#a3514b38abe732117ce44f51d28fd2838>method.)

Now i wonder how unsigned char scalars are treated as colors. Do they 
mean unsigned char vecors with 3 components for RGB?

Best regards,
Henry
