The component is set as follows:
where N is the number of entries in the colormap (i.e., the value of dims for the lattice).alpha(i) = 0.0; 0 <= i < Limit1; = Value1; Limit1 <= i < Limit2; = Value2; Limit2 <= i < Limit3; = Value3; Limit3 <= i < N;
Port: Input Colormap
Component value for indices Limit1 through Limit2-1.
Component value for indices Limit2 through Limit3-1.
Component value for indices Limit3 through N-1.
End of first range of indices.
End of second range of indices.
End of third range of indices.
Port: Output Colormap
Output colormap, with modified alpha channel.
Note: the VolumeRender module is not available for all ports of IRIS Explorer.
