to every point is one and only one value and regardless of colormap or<br>
lookuptable they only map one value to one color.<br>
<br>
Say that i tie value 1 to a color, then i still have the ability of [1,0,0],<br>
[0,1,0] and [0,0,1] if my structuredPoints have 3 separate values to them<br>
(and even more possibilities if the mapping is done with absolute values)<br>
Instead of<br>
AddRGBPoint(value,R,G,B) or SetTableValue(value, R,G,B,alpha)<br>
i would like to have some way of specifying<br>
AddRGBPoint(val1,val2,val3,R,G,B) or SetTableValue(val1,val2,val3,<br>
R,G,B,alpha)<br>
<br>
This makes sense to me since vtkStructuredPoints have the method<br>
SetNumberOfScalarComponents()<br>
(Mathematically speaking it is "just" a question of interpolating piecewise<br>
functions in 3-space instead of 1-space)<br>
