Hi PaQ.

Thanks a lot for sharing. Much appreciated!

@You : "...It's not like you just buy a license, read the documentation and start produce amazing 'stuffs'.
In this learning journey, the apprentice edition is the way to go..."

You're right and I totally agree with you.

In fact, beyond my limited budget, the other true thing is that by now I don't have enough free time to discover and learn Houdini.

With the small amount of "true" free time that I have I can only make some little step forward in learning the
other main software of my current pipeline : "Instant Light", Blender, Moi, 3D-Coat, NVIL, Affinity Photo/Designer, PaintStorm Studio.

I'd really like to learn a great software like Houdini and I hope to do so when it will be possible.

Anyway, thanks again for sharing.

Bye.

Hi STEFAN.

Thanks a lot for the reply.

Bye.

Hello,

Imagine if the export in MoI would provide this edge breaking option for meshes.

Hi Marco,

You: This is a simple "non sense" model in Moi. Very, very difficult to fillet, maybe impossible...

I think if you would have modeled more cleanly, then there would be no filleting issues, prior twisting... :-)

Hi STEFAN.

Thanks for sharing but...maybe I'm not being clear :)

I intentionally created a "non sense" model just in order to talk about a situation where you have
some kind of model and you don't want to waste time and brain energy to find a suitable way to perform the filleting in Moi if you DON'T NEED a REAL FILLET.

I know that modelling in this way may lead to use Moi in a bad way, but my aim, for specific scenarios, is just to use Moi
for what it was created, that is, fast and easy 3D concept modelling.

So I think that, for some situations, it's a good thing to model all the main stuff and forms in Moi and create
the other supporting stuff, like the "round edges" for example, with other workflows like 3D-Coat or Houdini or Blender or other.

See you.

Hi PaQ.

@You : "...the apprentice edition is the way to go (and yes you can export .obj without any restriction as far as I know)...."

Wow...great things to know!! Thanks a lot.

if the obj export from Houdini Apprentice its not restricted version compared to Houdini Indie then this is getting interesting!!

Even if I will use (for the moment) Houdini Apprentice just only to perform the "round edge" or "fake filleting" it's enough for me.

So I'm going to install and test Houdini Apprentice, but as i said, I don't have time to learn this HUUUGE software,
so for the time being, I will use it exclusively to test the "round edge" capability.

Please PaQ could you tell me which are the necessary steps to perform to get the same results you showed me in your post: http://moi3d.com/forum/index.php?webtag=MOI&msg=8512.6

A little minimal tutorial for 1) importing obj into Houdini 2) perform the "round edge" 3) export to obj in order to import in 3D-Coat to paint and texture.

I stay tuned. Thanks a lot.

Hi Marco,

Well the sequence of nodes are visible in the image posted, but I can share a houdini scene.
You can right-click anywhere in the node graph and export the geometry.



Here's a more extreme example from a GrabCad model ... poly count is around 200M tri's.

Hi PaQ.

Thanks a lot for instructions.

@You : "Well the sequence of nodes are visible in the image posted, but I can share a houdini scene.

Well...ASAP I will try to do a personal test based on the image you posted some day s ago.
If I will need help I will ask you far a Houdini example scene.

I will let you know the results of my test.

Thanks again and have a nice day.

Stupid me...

Me: "However i have not tried PaQ's technique yet, because i don't know
how he did it, nor do i have so much RAM.

So maybe he can explain to you on how to accomplish this."

Next time i should better scroll to the right side of large images... !!!

Stefan

Hi PaQ, if you can find it again easily can you please share the link to that GrabCAD engine model? Thanks!

- Michael

Hi Michael,

Here's the model : https://grabcad.com/library/engine-v-twin-4-valve-heads-1

Thanks PaQ, that's another good one for me to test with. Right now I'm experimenting with some ideas on speeding up the display engine for large models.

Sweeeeeeeeet :)

Hi PAQ
Can you show me how to process in Houdini ?
I don(see the sequence of nodes in the image posted.
Thanks

Hi PaQ.

Echoing the words of Finema, I also need a little more help.

As I said some days ago, these days I've absolutely no decent amount of free time to learn the very basics of Houdini,
and I have tried to replicate the nodes you posted in your images but without good results.

I mean, I replicated the node structure (clearly without the loop, because I'm testing only one object) to have a starting obj model in input and an ending node that should have created the object with rounded edges, but I think I did not quite understand the way the node "VDBfrompolygons" works.
Does it makes some sort of "voxelization" ?

The image you posted is not enough detailed to see it clearly.

And as resulting obj file I get is a tremendously huge 300 MB obj file, while the input it's only a very simple test file of less than 100KB!

I'm doing something wrong...

My aim is to get better results compared to 3D-Coat only for this particular very common operation (round sharp edges).
I mean better in terms of workflow, speed, quality results, lightweight model.

Actually I only know the 3D-Coat method and i would like to compare it with Houdini.

Please, could you post an example Houdini scene containing the minimum node setup in order to perform an example of "round edges" workflow ?


Thanks a lot.

Hi Michael.

@You : "...Right now I'm experimenting with some ideas on speeding up the display engine for large models..."

Very good news!!

Have a nice day.

Hi PaQ
can you post a Houdini file sample and we could replace the mesh
thanks

Hi Marco,

i tested PaQ's set-up today and since i could not read the numbers for the Voxel size, i used 0.0001 and got
this result with your test model. Your model was saved in MoI with 3 as Angle an 1 for divide larger then.
After that i reduced the model with Atangeo Balancer to 10 percent in size and finally used the GTK Remesher
to make the triangles distribution look better, with a vertex count of 125.000 vertices. I had to do this,
because when i looked in close-up (in Mesh Lab) the surface from the Houdini mesh looked not smooth,
it was more like a bit bumpy and facetted. When time permits i may check out this procedure in more detail.

When i saved your model from Houdini it had a file size of 156 MB, if i remember correctly.

Stefan

So here's the Houdini project file.
https://drive.google.com/open?id=0B81ES6gGfOHSX254RVpBRVZLN28





The setup will split and voxel object individually. I also manage to reassign MoI styles back on the 'voxeled' model,
but it only seems to work when using .abc format.
To get the best result, Moi 'divide larger than' meshing option should barely match the voxel grid resolution.

I also use the adaptivity option in the convertvdb operator, to slightly reduce the polycount.

Thanks a lot PaQ for explaining "for getting best results and adaptivity option" settings, much appreciated!

Stefan
