| MESHLAB Uniform mesh resampling PROBLEM* [message #63325] Wed, 06 March 2013 02:30 UTC |

Hey Yall,
I've been looking for a good way to add thickness to my models for uploading. I'm also trying to teach my students how to hollow models. We have been using Zbrush with good results but there is no way to be precise with this.
I have been trying to use MESHLAB's Uniform Remeshing filter but not with much luck. The settings I am testing I have attached a screenshot of.
After using this function I do have a new layer called offset but there doesn't seem to be anything in it??? No faces or vertices I'm very confused could someone please help.
Thanks
C

OK this is very helpful! But I still am a bit confused or curious if there is a way to control the thickness?
What I mean is there a way I can chose exactly how thick the offset mesh is going to be?
The values I'm entering that have been working for me are attached to the image below (which are working). It seems that by changing these just a little I get a really messed up offset mesh?
Do you have recommended settings?
Thanks much

If you know the dimensions of the model, you can specify the offset as the ABS value, otherwise you're stuck to calculating the offset needed. From the numbers for 'Precision' it looks like the model has largest length as 6.39 units, enter the 'world units' value for the wall thickness you need in the offset abs box.
The reccommended settings are those that are right for the size of the model and the material that the model is intended to be printed in.

Okay great ! So The precision that I have now set at 2 is ok?
It seems to do the same things wether that is 1 or 2
I finally understand the offset abs box but what is the precision box for?

Presicion is how fine you want the new mesh to be. The smaller the number, the more smaller faces will be generated.
