Tetrahedrons

Hi.
I am looking for a method (procedure) to divide any volume (solid) into three-sided pyramids (tetrahedrons). Somewhere the term crystallization is also used. I have already gone through many tutorials, but I am not successful, I am a beginner. I got to the 3D delaunay tool, but I cannot set it up so that it divides the volume into the required number of pieces via the “number sliders”. Can you please advise me?
Thank you.

search for plankton mesh and for 3d delaunay cell.

Thank you for your time. I’m a beginner and I can’t figure out what you sent me. Can you please send me an object divided into tetrahedrons? Thanks again.

How does the result of this definition look?

Hi Pavol, can you please explain what your problem is or even better SHOW it? in your first post you do mention the delaunay - what trouble do you have to use it?
I did show you that it does create closed meshes. 4 triangles each. given a point distribution.
So what difficulties are there? distribute points on and in the volume. and culling the tetrahedrons outside our volume. (when the volume is concave the delaunay does create pyramids outside too…)

my example is random - a random ugly volume populated with random points for the meshes
do you have trouble to create a regular point grid?

it can be difficult (impossible?) to get a precise number of tetrahedrons describe your volume.
but when the definition runs the number of meshes could be optimized (manualy or using galapagos?)

Thank you very much.

It took me a while to figure out how to display it. I can see it now.

It’s great, it really moved me forward.

The problem is that there are so many lines.

I would like it if it were an object divided into layers of variable thickness.

I’m learning this method so that I can make real objects in the future. The individual rods could be made of iron and their size would depend on the type of object, but they could be bigger than a person.

Thank you for your time.
