    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>
    <br>
    Regards,<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>
      <br>
