BVTKNodes gallery

I’m starting this thread in a hope to form a gallery for scientific visualization renderings which utilize BVTKNodes add-on (original repository by Silvano Imboden, and my fork repository). BVTKNodes is a Blender add-on which allows creation and execution of VTK pipelines in Blender Node Editor. I hope that people will post and tell here how they have used BVTKNodes. Both renders and node tree images are welcome, since examples are the best way to learn. Feel free to post and also discuss! Are you using Blender and VTK?

Here is head data show case example:


Kitchen flow example, stream tracer + tube filter, coloring by integration time.


Just added fin example to my fork. Domain outline with tubes, plane slice with density data, and arrows from momentum vectors. Tried two different lightings.

Ok, this one is more art than scientific visualization, but the stream tracer ribbons in pictures do originate from CFD simulation. This is the OpenFOAM motorbike tutorial case (laminar SIMPLE solution), including the motor bike model (triangulated model --> reflections artefacts). The only thing I did was add smooth shading to faces, otherwise model is original.

This is a bit of a breakthrough for me, to get OpenFOAM data via BVTKNodes directly into Blender. Attached also image of node tree. Warning: Reading OpenFOAM cases with BVTKNodes like this has many many limitations. It took me quite some time to make this work.


Here is a visualization test of the computational hex-dominant volume mesh (created with SnappyHexMesh) for the same motorBike tutorial case, using latest add-on version. Color ramp (blue-to-red) goes from 3 to 6 refinement levels. 21 million verts in final Blender mesh, almost too large for my machine to render :slight_smile:.

Here is example of two overpressure isosurfaces (using two vtkContourFilter nodes) around a flying object. Smooth shading, no extra mesh manipulation.

Nice to see that this is actively developed.
