Modeling for bas relief - Page 2 - Polyloop

H20diver · 19th December 2007, 21:12

One last thing... This guy is really good at modeling in Silo and creating cnc reliefs but I think Silo is poly? Would this also work?

Here is a link: http://www.silo3d.com/forum/showthre...ht=2.5d&page=2

Thanks again for everyones help!

yup, my comment about the advantage of Nurbs is that it remains "scalable" for large or small work. But if you are good enough to model your poly mesh with proper subdivision topology, then you can just move increase/decrease smoothing levels to adjust mesh for larger work. Although each subdivison level will increase your poly counts by 400%

. Whereas a Nurbs can be remeshed to and show a much lower increase in poly counts... There is no doubt you can achieve great results using subd modeling for this type of project. But you are sort of "locked in" to a certain topology. So you will have to plan for this more carefully than you would using nurbs... It's all up to your preference... I am sure any Nurbs modeler out there (Rhino included) can export a proper mesh for your CAM system...

Yessir.

With a hammer and a chisel, just like old Mikey.

Talking about Rhino etc I think is a bit out of line here.
Hexagon will save to the file types required and is the cheapest. And I think that, at this stage, that is the MOST important.

If working with a friend, it may be worthwhile using Silo (at a higher cost) as you can better communicate.

3D Brush is a bit more problematic in saving to a suitable file type. Really only .obj.

How is it out of line to talk about Rhino? The question was asked in the first post whether to use Nurbs (Blender) or polys for such a project. I am not sure about the Nurbs modeling abilities of Blender. So i think it is appropriate to make suggestions on what software might be used to get the best results. Rhino is powerful in this type of surface modeling...

Also i don't recall any budgetary constraint being mentioned. CAM software itself is more expensive than most low-budget Nurbs modelers...

Sorry. I understood it was a "newbee" to modelling. That would put Blender lower on the list I suggest, and especially, Rhino and Z-Brush.

My suggestions are towards that "newbee" spending the least, but with effective reasonable learning attributes, for the money ,to start with.

Is this the technique you were trying with ZBrush?
(Wasn't aware that CNC offered much detail in production anyway)

ZBrush Bas-Relief technique - This would be for someone adept at modeling or using ready-made models that would be imported into ZBrush.

I am going to be trying some of this style of modeling to suggest an alternative product for the folks who are making figurines from some of my doodlin's. (Wall-plaques as an addition to their figurine line would be economical in retail pricing as well as for space in the store's sale display).

Just a quick example of working with 3D Brush.
