looking at your grid example, in that case exagon is the best way to go, bacause you need to tile your rows "alternate" but in the case of a "stack bond style" tiling, that same base topology could be quite problematic..

so definetly, it depends on the shape/topology you are tryng to achieve.


Yes sure, what I am saying is to build tubes, and as you have seen in the T Pipe tubes the best sample I have done was by using octagons, the main shape recommended to subdivide is the square, mainly known as Quad, it may vary according the model of course.

It's the de-factor subdivision standard that's being adopted. Originally developed by pixar: http://graphics.pixar.com/opensubdiv/docs/intro.html

Next version of SUbD will use OpenSubdiv as the subdivision engine - so it'll subdivide consistently with other applications that implement OpenSubdiv.

Well honestly I have no idea if Carrara does have that, however I have done several tests in this program and the process to subdivide is quite similar to other 3D programs such Maya, Blender and others, I am very excited about the SU plugin you have developed, I did install it a few months ago, I was trying to upload more samples but my trial has been expired, (so sad) Will post some other samples soon.

Regards!

That is strange, it is my normal Imgur account which you have seen on FB.
The gif was too big to upload directly here.
I'll add a screenshot for you.

A friend of mine just finished a reprap 3d printer and I thought to "celebrate" his achievement, by modeling a boat for him to print...

Been a while since I posted anything here!

Quick model I did earlier this week:

I had a jpg image of my friend's logo, I imported it in Inkscape -> Trace Bitmap -> Save as DXF

Imported in SketchUp + Thomthom Edge Tools -> Simplify curves (I had to weld all curves before), then
Sandbox Drape + Fredo JPP

*sandbox drape works only on blue axis, so I had to turn the boat on a side for that operation.
** i did the letters on the plain mesh, after using subD and converting it into plain mesh.

Do I get you right - the 3D text remains a geometry of it´s own?

To reduce the geometry to what is just necessary always looks so simple but is the challenge ;)

So is this logo quad also? Is he part of boat geometry or is it by it self another quad model.
If it is part of boat geometry how did you do it and maintain quads on boat?

I do expect pic of printed boat!? :-)

I even did a video of the model, for anyone interested...

No. The 3D text is "draped" and then extruded from the boat's hull mesh. But that could be done only after the boat was subdivided using subD. After the subdivision, if you right-click on it, you will se a context subD menu that converts the parametric mesh into a plain mesh... that can't be turned back to low poly anymore. Is just a simple standard triangle mesh surface.

So, on this surface I used the Drape Tool from Sandbox to imprint the text outline. Then I used Fredo's PushPull over that outline.

Yeah... even though it was a quick model (25 minutes) I did speed it up for the video... but I did leave it all in there! Even several "oops" moments!

I definitely expect that too... he promised that he would do that on Monday... due to the reason that he has to fine-tune the printer. Right now he's printing with 0.3mm nozzle and had some speed problems. But he promised to go with 0.1 (which my model deserves).

Well, is plastic...and you know that 3D printing software makes that honeycomb structure inside... so I expect it will float... but I can't guarantee it won't be upside down :mrgreen: I didn't do any buoyancy calculations, not even to find its center of gravity... (tig has a plugin for that, right?)
