Hello all, <br>
<br>
I have an rgb image that I created and contains a color gradation
i.e. the color spectrum. <br>
I have tried using the vtkColorTransferFunction to add all the
colors but this causes the application to lock, I guess for the
large lookuptable takes a long time to process.<br>
<br>
I have also tried adding some colors like this:<br>
<br>
<blockquote>colorfunction->AddRGBPoint( mingreyvalue, r, g, b);
//the grey value is a double<br>
colorfunction->AddRGBPoint( maxgreyvalue, r, g, b); <br>
colorfunction->Build();<br>
</blockquote>
<br>
But this doesn't do the trick, I just shows the colors correspoding
to min and max. <br>
<br>
I've seen that in applications like volview, the image is shown
correctly and it doesn't take a long time to load or anything, so I
guess there is an efficient way to build up the lookuptable that
shows the correct values for every voxel.<br>
<br>
Please any ideas or comments are welcome.<br>
<br>
Thank you very much,<br>
<br>
