                    volume rendering is working on the wavelet dataset.<br>
                    <br>
                    You do need the scalars for volume rendering, so
                    make sure you have those when you try. You need to
                    select the scalars in the drop down also, I usually
                    do this before changing to the volume
                    representation. You also may need to edit the
                    transfer function. For testing you could make the
                    opacity over the entire scalar range in which case
                    you should see a solid cube.<br>
                    <br>
                    If you've done all that and don't see anything it's
                    likely that the dataset is messed up.  Add a
                    dataset->Print(cerr) statement to the end of your
                    request data,  look in the information panel and
                    verify correct number of points and scalar ranges. <br>
                    <br>
                    If all else fails post the dataset to the list.
                    After creating your cube go to the file menu and
                    "save data".<br>

                      three 3 picture, in all 5 volume rendering mode
                      (smart, raycast and texture mapping, ray cast
                      only, texture mapping only, GPU based). The
                      picture a rather fuzzy, but then I don't know what
                      I'm supposed to see here. The good news is that
                      the openGL errors I had before when displaying a
                      wavelet, now have gone.<br>
                      <br>
                      The situation with my own cube, though, has
                      unchanged. unfortunately.  <br>
                      The cube disappears in "volume" representation
                      node, also when I  re-inserted scalar values for
                      each of the 8 vertices.<br>

                        <br>
                        In recent releases of ParaView I have
                        experienced issues/flakeyness with volume
                        rendering. Something you should try: Create the
                        wavelet source, then in the properties panel
                        find "volume rendering mode" and set it to "ray
                        cast only".  This has worked for me on a number
                        of systems. may or may not work, but worth a
                        try.<br>
                        <br>
                        The output you pasted below shows that although
                        you've got a sweet ATI GPU you're not taking
                        advantage of it! You're using the Intel
                        integrated GPU with Mesa drivers. If I were you
                        I would install proprietary the <a
                          moz-do-not-send="true"
                          href="http://support.amd.com/en-us/download"
                          target="_blank">AMD drivers</a>. This should
                        give you nice performance boost and may even
                        solve the OpenGL errors you reported, which
                        these days are as often (or more) a result of
                        bugs in the Mesa drivers than in VTK.<br>

                                                  <br>
                                                  Thanks for the
                                                  suggestion.<br>
                                                  <br>
                                                  However, doing this
                                                  gives me all kinds of
                                                  opengl errors (invalid
                                                  instruction).<br>
                                                  <br>
                                                  Besides that, the
                                                  wavelet gives me a
                                                  cube indeed, but I
                                                  need to understand
                                                  when <br>
                                                  I can have a volume
                                                  rendering. I created
                                                  new Source's (e.g.
                                                  tri-prism, a wedge, <br>
                                                  a box with boundaries
                                                  of finite thickness
                                                  etc.). But I cannot
                                                  get volume rendering<br>
                                                  to work, grrrrrr. (See
                                                  other thread)<br>
                                                  <br>
                                                  Kind Regards,<br>
