High-quality Visualization with ParaView and OSPRay

Once finished your scientific simulation, you might ask yourself:
is there any smart way to create a nice visualization with ray-traced surfaces?
Sure, and it should not be rocket science! However, it might be a little bit tricky to find out how it exactly works. But I hope to bring some clarity with my short article.

During one of my first post-processing tasks for my CFD simulations, I came across the animation functionality in the ParaView software.

To clarify, the official documentation can be found here: in the Kitware Blog. There is also some additional specific info related to OSPRay on the cornell.edu page.

For my animation, which is placed at the end of this page, I used the integrated OSPRay Rendering in ParaView. Besides, the video has been rendered with the Open Source Tool kdenlive. But in the meantime, I also use the OpenShot software, which became my favorite one.

By using some smart Linux CLI commands for picture processing, one could add also really awesome functions and effects to his projects. ImageMagick is one of these tools.

Check our short list with most useful Linux CLI commands for GIFs and video modification.

The main procedure in ParaView is shown on the pictures below.

More detailed, step-by-step instructions can be found on the DEUTSCHES KILMARECHENZENTRUM dkrz.de page.
