No we don't have a mean (or xray) function. It should be relatively straightforward for you to take vtkVolumeRayCastMIPFunction and modify it to create a vtkVolumeRayCastMeanFunction . If you do succeed, please feel fee to contribute it back to the VTK Journal (<a href="http://www.midasjournal.org/?journal=35" target="_blank">http://www.midasjournal.org/?journal=35</a>) . In fact somebody posted the mean function, (see xray function) on the vtkusers list a while ago :<br>

Hi everyone <br><br>I'm working with vtkVolumeRayCastCompositeFunction but my results aren't excellent. <br><br>I know that there are other two methods to do something similar: <br><br>-vtkVolumeRayCastIsosurfaceFunction<br>
-vtkVolumeRayCastMIPFunction<br><br>But I would like to have a sort of AIP=Averaged Intensity Projection Method... Does it exist something similar in VTK? Could anyone help me?<br><br>Regards<br>Daniela<br> <br>
