Hello all scientific visualization people interested in photorealistic rendering!

I've been upgrading this amazing add-on for Blender >2.80 called BVTKNodes, originally created by Silvano Imboden and further developed by Lorenzo Celli for Blender 2.79. BVTKNodes makes it possible to create and execute VTK pipelines configured in Blender Node Editor, to produce surface mesh objects, which can be then visualized in Blender using it's rendering engines. This makes it possible to create photorealistic images and animations of scientific data in Blender (provided that you know both Blender and VTK well enough!). For more information, have a look at https://bvtknodes.readthedocs.io

Unfortunately I didn't get images to work in post, so please check out these links for images:

Here are examples of useful node setups for CFD: https://bvtknodes.readthedocs.io/en/.../ug_nodes.html

BR,
Tuomo

Hi,

sorry no, only the part how to get the meshes into Blender is described in the docs I gave link to. The rest (moving of objects, creation of background plane object for visualization, setting up camera, setting up lighting and world background, modification of materials for objects, modify settings for rendering engine, rendering of image, possibly composition and finally saving of image file) is Blender stuff, for which there are vast amounts of tutorials on-line.

BR,
Tuomo
