Hello,<br>
<br>
i am trying to understand the color mapping of vtkMapper and i am
reading the doxygen.<br>
It is stated:<br>

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

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