<DIV><FONT face=Arial size=2>I have not used such (four component) volumes but
documentation indicates that vtkFixedPointVolumeRayCastMapper can handle such

<DIV style="FONT: 10pt arial"><B>Subject:</B> [vtkusers] Can volume rendering
be true color?</DIV>
<DIV><BR></DIV>
<DIV>Hi all,<BR><BR>Currently, I see only volume rendering with pseudo color
mapping, the opacity and the color are set according to the scalar
values<BR><BR>Now I have a series of true color images, which are taken for an
object at different focus positions, read into vtkJPEGReader, and each point
in the data has 3 scalar <BR><BR>components
(vtkJPEGReader::GetOutput()->GetNumberOfScalarComponents() == 3). I wonder
whether there is a method to set only the opacity<BR><BR>of the points in the
data and perform the volume rendering to obtain a true color volume rendering
objects.<BR><BR><BR>Thanks in advance!<BR></DIV>
