Re: [Paraview] BOX -> volume?

Tue, 14 Oct 2014 09:07:52 -0700 

Hi Bertwim,
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. 


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 AMD 
drivers <http://support.amd.com/en-us/download>. 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.

    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?
