Triangles to Quads

What software do you use to convert from triangles to quads in your meshes, I’ll be honest, preferably free. I think there is a paid add on for Fusion which I’d be tempted to use if I had to spend money.

Also is this something Revopoint would ever think about adding to that Revoscan Software?

Instant Meshes. It’s free and works perfectly.
See my guide here: From scan to CAD. Two ways using MIRACO

Instant Meshes here too

What are the advantages of having quads instead of triangles?

“Quads” does not only mean there are four-sided polygons but usually this means also having an edge-flow based on loops. Such a grid-like structure is necessary to enhance the object further (cut, unwrap, deform, …). I do this retopology in 3dsMax, as I have a licensed version here.

Many CAD application can convert quads in to an editable solid. They struggle with triangles.

Quads are very usable if you want to edit it, create new UVs, modeling , remodeling , unbiased animated model rendering , animation , rigging , material groups and many others … more organized and easy to work with . 3D modelers would prefer quads over triangles and 100% when model is used for rigging in animation .

Triangles are not much usable in my pipeline unless it is some static prop in a background .or used for reverse engineering.

Hi Gary,

Yes, the requirement of “applying quads in mesh” will be technically evaluated for product planning.

Thank you all for your responses,

@Rilot I did see that in your post, and will be looking at how to use it, I see you get good results.

@Revopoint-Jane it’s great to hear it taken on board, thank you, let’s hope it’s something viable for the future.

Hi Jane, has there been any progress on OBJ Quads? Fusion has a workflow for using quads; it would be really nice to go straight from scan to cad :slight_smile:

Fusion 360: The Tri to Quad mesh feature is available in the product extension and with Commercial or EDU license types.

Hi Chris,

Thank you for asking. I will check with the dev team on the progress. Thank you for your patience!

Hi! Thanks for the input :slight_smile: this is actually the workflow which brought on my question. We currently have 3 seats for fusion and none of them have the plugin which is $499 cad. Im using the 14 day trial and converting tri from RevoScan to form in fusion works well for what we are doing… but its not worth $500 per year! I can get the same results converting quads to B-rep with fusion’s included tools without spending anything extra. Hopefully revoscan can include the quads option soon! Thank you

Hi
Have you already tried the freeware Instant Meshes, like proposed by @rilot? It is one of my favourite postprocessing tools, great for remeshing and converting to quads.

I don’t think it going to be soon , because the team is very busy at this moment .
This requires a new coding and not overnight job .
On top the conversion of scans to quads will be so huge in size that may be a problem for users with only 16GB of RAM if you want to keep the same accuracy .
That is the major issue since RS5 was not build to handle this kind of files , the processing gonna be too slow and take lots of time .

That why this is not a quick fix here and needs time.

There is plenty of free software doing the conversions , including Blender as well and Instant Meshes.
So until then I suggest you try them out after your free trial ends .

I know it would be great to have the conversion in one program , good stuff come to those that can wait :wink:

Hi Ivan, I’m sure the freeware is effective however, At first glance looking at the GitHub repository it seems you have to install the program using python commands and that’s just not my cup of tea! I’ve already contacted my rep to see if there’s anything Fusion can do.

Hi!

That actually, while often the case with other software from github, is NOT the case with this one as there are precompiled binaries, see here from about mark 2:18 :slightly_smiling_face:

So it is one click to download and to open :slightly_smiling_face:

There are only two things to take care of. Your 3d model has to be in .obj-format. And when you save the file, it is mandatory to write the ending “.obj” at the end of filename, otherwise it will not save.

I would give it a try as it is free, gives great results and very (!) easy to use.

cheers

Thanks Ivan, I got it running tonight and although I have to experiment with it a bit more, it works well which is more than I can say about the fussy nature of fusion 360!
