We just finished illustrations and an animation for an orthopedic client of ours showing a highly porous material made from titanium on an implant. The material shape is a lot like porous bone. Ran into dead end after dead end trying to do it in x-particles and R20 volume modeler (both of which we use constantly and love, btw). 2 days later we installed the latest Proc3durale plugin and nailed it 10 minutes later. Could not have done this without it and wanted to give Code Vonc their props. This plugin was perfect for this situation.
Proc3durale plugin saves the day

Looks great Troyan. We are tasked with creating spongy bone like that quite often. Used to use procedurale years ago but have resorted to other methods since. Worth looking at again.

No need for the plugin if you have R20 volumes working.
Especially if you have EnhanceC4D + Insidiyum bridge working. Lots more noises to play with.

I’m sure it’s possible but not to the degree of ease and speed that Code Vonc’s plugin does. We tried R20’s volume modeler with noise shaders and it was frustrating and slow by comparison for this task. We’ve used the volume modeler a lot for other things but it was just not doing for this task.

Actually just went into R20 and it is pretty fast if you work at the right scale. HEre are some stills of the workflow:
Cube > voronoi fracture > select edges > convert to spline > Volume builder and mesher with offset scale and smoothing > displacement to mesh at the end. You need to make sure you are at a fairly large sized object or will be longer/hardeer to caclulate. I also added 3 planer directional displacemers to the splines (an X Y and Z)

That looks awesome and a great workflow, but the key things there are “cube” with nice clean even geometry and getting the size right for the calculations :). We’ve made a lot of bone lattice environments with that method, but used metaballs in the past. We applied Proc3durale to a cad import model for this illustration. I’ll give this approach a try the next moment I have to breathe and see if that works out but I’m not optimistic on a non-cube model :).

Cool–FWIW–I think the vornoi fracture methid should theoretically work with any volume/shape. Once you have the edges splines, the volumes give you a lot of control.
Congrats on the project.
(edit–I see what you mean. An object with a dense mesh will not nly generate voronoi edges, bit the poly edjes that were there at the start will give you splnes as well. when those results are meshed you end up with the mesh grid, which isnt what you want)

Actually–I take back my last disclaimer. If you do a phong selction on the voronoi fracture edges, you should still be able to get splines that just define the outer edges of the voronoi chunks (not the underlying mesh grid of the model). So yes–this should work with cad models (though might be time consiming to calculate)

You need R20 to use the new Volume builder. There are definitely other tools you can use–but pointing out it
can all be done natively.

Well, using the fracture tool isn’t exactly the same thing. If you try to make the original mesh or the attached using Cinema’s volume builder and noise shaders, in my experience, it’s going to be much more time consuming and slow your machine down incredibly.

Nice technique Joel. Really useful for a 3D printing idea I had in mind, but hadn’t thought about it in this way…
Good thread. More like this…

Another thought is that X-particles is wonderful for this kind of stuff. Emitting from a texture using an animated noise and then adding xpOVDBMesher works great and it is so easy.

Thomas Browns NAB presentation was GREAT!!! It really shows you the power of Volume modeling–stuff I hadnt considered.
And thanks Priest
Didnt mean to Shanghai the thread Troyan into a technique discussion–really nice work!
