map scalar values into colors via a lookup table
<p>
<a class="el" href="a00980.html" title="map scalar values into colors via a lookup table">vtkLookupTable</a> is an object that is used by mapper objects to map scalar values into rgba (red-green-blue-alpha transparency) color specification, or rgba into scalar values. The color table can be created by direct insertion of color values, or by specifying hue, saturation, value, and alpha range and generating a table.<p>

Force the lookup table to regenerate from hue, saturation, value, and alpha min/max values. Table is built from a linear ramp of each value. <a class="el" href="a00980.html#0ab1e76909ca6485807db5316b9fa037">ForceBuild()</a> is useful if a lookup table has been defined manually (using SetTableValue) and then an application decides to rebuild the lookup table using the implicit process.

Set the shape of the table ramp to either linear or S-curve. The default is S-curve, which tails off gradually at either end. The equation used for the S-curve is y = (sin((x - 1/2)*pi) + 1)/2, while the equation for the linear ramp is simply y = x. For an S-curve greyscale ramp, you should set NumberOfTableValues to 402 (which is 256*pi/2) to provide room for the tails of the ramp. The equation for the SQRT is y = sqrt(x).
