    Progress indeed. But I don't understand what you are saying about
    the transfer function.<br>
    <br>
    I' starting to wonder if I have two issues occurring simultaneously.<br>
    In a new thread I just posted I described my problem in getting the
    colours in place.<br>
    I need to write to a vtk file first and load it back.  I just found
    that when I just did that<br>
    and then switched fo volume rendering, an error was there about the
    absence<br>
    of an opengl extension:<br>
    <br>
    ERROR: In
    /usr/local/git/ParaView/VTK/Rendering/VolumeOpenGL/vtkOpenGLProjectedTetrahedraMapper.cxx,
    line 185<br>
    vtkOpenGLProjectedTetrahedraMapper (0x58ae490): The required
    extensions are not supported.<br>
    <br>
     This is complete unknown terrain for me.<br>

      progress!  it sounds like 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>

        Hi Burlen, <br>
        <br>
        I have upgraded to the AMD drivers. Thanks for the hint. It has
        improved the situation a bit.<br>
        <br>
        Furthermore, I created the wavelet source. When selecting
        "volume" representation, I do see a 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>

          Hi Bertwim,<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">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>

                                    Thanks for the suggestion.<br>

                                    However, doing this gives me all

                                    <br>

                                    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

                                    volume rendering<br>
                                    to work, grrrrrr. (See other thread)<br>

                                                perhaps somebody point
                                                me how to address the
                                                following.<br>
                                                <br>
                                                When I create a new
                                                source (say: a box) I
                                                get an a box that<br>
                                                can be displayed via its
                                                surfaces, its
                                                constituing points, or
                                                wireframe<br>
                                                representation.<br>
                                                But I need a volume
                                                rendering (so that I can
                                                add e.g. a clipping
                                                plane)<br>
                                                How do I get that?<br>
