Re: [Paraview] BOX -> volume?

Burlen Loring Tue, 14 Oct 2014 12:59:27 -0700

progress! it sounds like volume rendering is working on the waveletdataset.

You do need the scalars for volume rendering, so make sure you havethose when you try. You need to select the scalars in the drop downalso, I usually do this before changing to the volume representation.You also may need to edit the transfer function. For testing you couldmake the opacity over the entire scalar range in which case you shouldsee a solid cube.

If you've done all that and don't see anything it's likely that thedataset is messed up. Add a dataset->Print(cerr) statement to the endof your request data, look in the information panel and verify correctnumber of points and scalar ranges.

If all else fails post the dataset to the list. After creating your cubego to the file menu and "save data".

Hi Burlen,
I have upgraded to the AMD drivers. Thanks for the hint. It hasimproved the situation a bit.
Furthermore, I created the wavelet source. When selecting "volume"representation, I do see a three 3 picture, in all 5 volume renderingmode (smart, raycast and texture mapping, ray cast only, texturemapping only, GPU based). The picture a rather fuzzy, but then I don'tknow what I'm supposed to see here. The good news is that the openGLerrors I had before when displaying a wavelet, now have gone.
The situation with my own cube, though, has unchanged. unfortunately.
The cube disappears in "volume" representation node, also when Ire-inserted scalar values for each of the 8 vertices.

Hi Bertwim,
In recent releases of ParaView I have experienced issues/flakeynesswith volume rendering. Something you should try: Create the waveletsource, then in the properties panel find "volume rendering mode" andset it to "ray cast only". This has worked for me on a number ofsystems. may or may not work, but worth a try.
The output you pasted below shows that although you've got a sweetATI GPU you're not taking advantage of it! You're using the Intelintegrated GPU with Mesa drivers. If I were you I would installproprietary the AMD drivers <http://support.amd.com/en-us/download>.This should give you nice performance boost and may even solve theOpenGL errors you reported, which these days are as often (or more) aresult of bugs in the Mesa drivers than in VTK.

    Hi Aashish,

    This is what I do:
    1. start paraview
    2. Sources -> Wavelet -> Apply.
         A cube is displayed (Outline representation).
    3. Select 'Volume" representation"

    cube disappears. Then:

    So when you created a wavelet source and change the
    representation to volume you got the errors? Can you post
    those errors?

    Thanks,

        Aashish,

        Thanks for the suggestion.

        However, doing this gives me all kinds of opengl errors
        (invalid instruction).

        Besides that, the wavelet gives me a cube indeed, but I
        need to understand when
        I can have a volume rendering. I created new Source's
        (e.g. tri-prism, a wedge,
        a box with boundaries of finite thickness etc.). But I
        cannot get volume rendering
        to work, grrrrrr. (See other thread)

        Kind Regards,
        Bertwim

            Can perhaps somebody point me how to address the
            following.

            When I create a new source (say: a box) I get an a
            box that
            can be displayed via its surfaces, its constituing
            points, or wireframe
            representation.
            But I need a volume rendering (so that I can add e.g.
            a clipping plane)
            How do I get that?

            Regards,
            Bertwim
