Thanks for asking. We will be glad to give a discount when you buy Win+Mac.
We will check how this can be done with our shopping system.

Hi Atangeo,

Thats great, I'll probably buy a copy at the end of the month :).


Hi Pilou,

I did a quick test versus Zbrush decimation,

http://forums.luxology.com/discussion/topic.aspx?id=40386
(bottom of the page)

For models comming 'outside' zbrush (the modo rhino model in this example), Balancer is much better for the same reasons I posted here : no long micro triangle, no high valance vertex = better shading, especially when you optimize your model at a very low polygon count. Silhouette and shading lools better.

Now the story is different when you decimate a model created in zbrush, maybe decimation master use the subdivision levels info somehow when precomputing the mesh, but for the same polygon count, details are better preserved in zbrush.

But I didnt made tons of test either.

Thanks for the Meshlab link, I'll give a try ... when I have some freetime.

Cheers

Balancer 1.2 is available!
Now you can control face densities for selective reduction rate of
different groups/meshes/sub-meshes. For example, you can set
density of 5 to the head group of your model, to increase the density
of the head vertices roughly 5 times.
See this user guide page here: http://www.atangeo.com/guide/density

Hi Guys!

I would like to let you know that Balancer 2.0 released.

Balancer 2.0 features robust and easy to use
accurate pixel-based tolerance simplification.
Now you can easily obtain desired visual quality
just in one click, without thoroughly inspecting
simplified models at different triangle count.

You specify error tolerance in pixels (say 3 pixels)
and your viewport (say 1024 by 1024), and in one click
you get a simplified model, which satisfies your quality
requirement. From any viewing direction, the resulting
model's silhouette won't deviate by more than 3 pixels.

All the rest of new features and improvements we worked on
we also added to Balancer 1.5.1 for those who purchased
Balancer 1.x.

Here is a decimation with 2 pixel error tolerance
for 480 x 480 viewport:



Balancer is available for both Windows and Mac OS X as usual:

Hi atangeo

Please correct me if I'm wrong.

I've just started working with MoI (3D modelling) with the intention of modelling some jewellery pieces that I will then get printed at shapways (3D printer)
Shapeways have a limit of 64MB file size and recommend max 1 million polygons.

Would balancer be a good tool for reducing polygons for simple surfaces areas? so I can "save" polygons for high detail areas?

Does anyone here know if Wavefront (.obj) is a good format to use a shapeways, I've been using stl sofar?

Cheers, steve

Hi steve,

I'd recommend using stl format for shapeways - in general stl is the standard format for 3D printing.

Also a binary stl file should probably be a fair amount more compact than an obj file.

Does Atangeo makes some similar thing like Decimation Master ? Better / Less / Similar ?

Hi Steve,

Balancer will do a good job by simpifying your model adaptively,
keeping as much details as possible given your required triangle count.

STL is the standard format for 3D printing. Right now, Balancer only supports .obj.
But we will release Balancer nPro just in a couple of weeks. It will have metric-based
tolerance simplification (not only pixel-based), and support of STL format.
Balancer nPro is exactly for simplifying models for 3D printing.

Hi Pilou,

Zbrush Decimation master is a good decimation tool,
but Balancer is more robust (no mesh artifacts, skinny triangles etc),
faster, needs much less resources and thus can work easily
with very large models, and can preserve more details given
the same triangle count. Also the latest version of Balancer
has a unique feature to simplify models down to your required
error tolerance. So, basically you get guaranteed visual appearance
without thorough inspection and adjustment of triangle count.

You may take a look at some comparison of
Zbrush Decimation master vs Balancer here:

Here is a comment by a Balancer user on ZBrush:

Many thanks for the precisions!
Ps And I have seen that was PaQ (a Moi fan) who made the comparaison test ! ;)

Hi atangeo,

Will Balancer nPro do any repair for the models that it simplifies? Like closing holes to make watertight, eliminating non-manifold edges, eliminating intersecting triangles, etc.?


Chris

Hi Chris,

Thanks for your question.
The initial release of Balancer nPro will only have watertight verification
in addition to the existing tools in Balancer, vertex joining and T-junction
elimination.

We will gradually add various mesh processing tools like those you mention.
Mesh processing is exactly the area of our expertise. :)

I tried the demo and it is way faster than the ZB Decimation Master!
Nice results and simple interface too.
