Hello Markus,
what worked for me was to change the version of blender (from 2.63a back to 2.62 I think), but I couldn't find a "true" solution to this problem.

All the best!

Hi,

so you still use an old version?

Can you track the error back?

https://projects.blender.org/scm/vie...s&pathrev=4362

or git

https://github.com/ldo/blender-addon.../import_x3d.py

I just downloaded the latest release 2.68a and have the same problem.

I will try to send a bug report or consult the blender forum.

Hello Markus,
yes, I'm still using 2.63a. Just tried importing an x3d file with 2.63a and the current 2.68. The 63a works fine (no black), the 68 gives the ugly black stuff. Did you have any luck with the blender community on this?

Here's sadly another problem (at least with 2.63): As soon as the x3d-file exceed a size limit of about 800 MB, the import won't work anymore (for a sinle file). If I split the 800 Mb file into two 400mb x3d files, it works....

always a lot do work around with free software
Cheers and good luck

here you will find the complete python script used in the blender python console to do the animations, i.e. read in the x3d files and do the videos in the thread:

cfdnewbie - I know this is old, but do you still have information on the scripts? Do you have a new link? I have an account on blender.org, but am still unable to see the thread.

Thanks!

Just wanted to add my contribution to the discussion. Many companies are moving towards that direction for marketing reasons.

Here's a cool video:

Wow, all of exacorp's video's are pretty stunning! Do you work with them lovecraft22?

I guess I could put a plug in here for a few videos I worked on. In some of our lab's biological fluid simulations, where the time history of the particles is important (blood flow & olfaction), I thought it would be interesting to animate the camera to follow a streamline:

I think that good visualization is not only useful for marketing, but also, if done correctly, for helping your audience understand the fluid mechanics.

By the way, have you guys seen the work from Oak Ridge:

or TotalSim?:

Let's keep this discussion going - it's fun to see the latest and greatest in visualization!

Ciao!

I recently made a small presentation to get a group of local openFoam users started with rendering CFD result using Blender. It comes with result files (in VTK format) that can be used in ParaView.

Presentation: http://www.slideshare.net/JuliendeCh...-using-blender

Files: https://s3.amazonaws.com/cfdresultsp...ng+Blender.zip

Feedback welcome.

[kingjewel1]

This is fantastic! Can anyone post the python code for to an accessible location? Blender forums says I'm not allowed to read the post unfortunately...

Cheers

Hi Julien,

thank you very much for these interesting slides. Unfortunately I can't access the zipped files any more. The link seems to be outdated. Would you, or anyone else, mind to post them once again?

Thanks in advance, best regards,

Kate

I like the squirrel nose. Always interesting to see what others simulate.

My favorite animation of the year is this one:

Hopefully the next OF user who is looking for this stuff doesn't has to spend an evening browsing the web

Thanks for your help!

This link should work:

Hi rendermen,

Using Blender 2.76 currently. Have someone find so far a way to get the x3d vertices color showing up in Cycles ? (my model is too complex for a clean texture baking)

Thanks!

[Svensen]

Blender 2.79 works OK

hello guys,
in case you are interested in rendering your CFD results in blender, we have a toolchain and tutorial available here,
You can also download the sample files from github


The toolchain contains some python scripts that automate most of the work needed. The only prerequisites are that you have paraview and blender available, which are both open source and that you can import your solution files into paraview.



Good luck and let us know if you encounter any issues.

Yes, this can be done via the node editor. You have to enable "use nodes" and add an attribute node with the Name "Col". See also the tutorial link in my other post for details on how to do this. It took me also some time to figure it out!
