Now we can export mesh animations to Blender.

Produced by Ready: Rendered in Blender.

Is the import mesh available to try?

very interesting! how can this be achieved?

+francesco arena 1) Get a copy of Ready.
2) Use "File > Start Recording > 3D surface" to output a sequence of OBJ files.
3) Import into Blender and render. If needed there's a script here:

+Tim Hutton tnx for fast reply!!!
I know Blender well enough.

I used Ready and opened bunny.vtu.
When I press start running simulation I correctly see reaction diffuse effect. If I do export mesh in obj, after in Blender I get a mesh without material or vertexcolor or texture.

The file works perfectly but I get lots of white without color information with only the restrict rendering and viewport visibility animated options.

Which tutorial do I have to follow to get a mesh with diffuse reaction 3d effect maybe even animated?

+francesco arena Ready supports two different ways of running RD systems:
a) vti files: values living on a regular grid: 1D, 2D, 3D images, and
b) vtu files: values living on a user-defined mesh: 2D polygonal meshes, 3D polygonal meshes, 3D polyhedral meshes.
(This could be better explained in the docs.)

bunny.vtu is (b), a polygonal mesh where the values are stored in each polygon. When you export the surface to OBJ (which doesn't support colors) the values are lost - the surface is the same every frame.

If you try it with e.g. parameter_modulation_demo2_3D.vti instead then this is type (a), a 3D image, which is contoured at a certain value to produce a 3D surface. Here the 3D surface changes over time, which OBJ captures.

So try it with a 3D vti file instead. If you really want to get the bunny.vtu animation into Blender then let me know - it is possible but not straightforward (we don't have texture coordinates).
