How would I model this glass?  1-20  21-29

Just as a practical example, how would I model this?

http://www.baccarat.com/en/home-decoration/arts-table/verres/HARCOURT-SERVICE/product/HARCOURT-SERVICE-CLEAR-CRYSTAL-GLASS--.htm

As I see it, there are 2 "challenges":

-Going from 6 hard edges at the bottom and various parts along the glass/profile, and:

-The 6 "grooves".

Thanks for any tips/responses!

Hi Duke,

You can use rail revolve for the bottom, revolve for the main body then surface cut....

Good luck ! :)

Hi Duke, I think the tools that Anis mentions are exactly right!

In fact it should come together really rather quickly.

With rail revolve you can build the whole bottom part with 2 curves, you draw the hexagon in the Top view, and then a profile in the Front view, so that they look like this when seen in 3D:



When you are drawing using the Freeform curve tool, hold down the Ctrl key when you click a point to make it a sharp corner point.

Then once you have those curves set up, select the Front profile one, and do a Construct / Revolve / Rail revolve:




After you run rail revolve, pick the hexagon as the rail path, and then pick the axis points on the z axis. That pops up one of the biggest chunks of your model right there!

Then like Anis mentions some other ideas for making more progress are to do a regular revolve for the vessel, and position something like an angled cylinder that intersects the vessel, then use Array Circular to make 6 copies of that angled cylinder and boolean difference them away to cut out those scallops.

Gave a it a shot, quick model actually, good exercise with nice results.

I did exactly as per Anis' and Michaels method except did each piece individually then Boolean union.
The main revolved glass cut outs, were Boolean diff with a surface that I mucked around with by manipulating the sweep curves until I got what I thought was ok. (History is my friend) :)
It might not be exact proportions I just eyed it off the screen, rendered in Hypershot.

Model attached if interested.







Cheers

Hi Pilou,

Good pick up, I didn't notice that, as I said it was a quick job I wasn't too fussed.
Oh yeah, you just reminded me, when I tried to do that blend with G1 the whole top part of the glass did a disappearing act.

Well i'm convinced. I modelled it in Max with polys, but its just so much cleaner and natural to do it with Nurbs. Although if I were to do it tomorrow it would be with MoI because I just bought it 5 minutes ago!

Hi Michael

i have forgot the name of the software you are using to make the gif tutorial/explanation, can you mention that again?

it have been mentioned in the forum before, but i could'nt find it, and it seems pretty good..

anyway, i really enjoy to follow the development of Moi, and am impressed about the effort and skills form your side.


best regards

// Leif

The most popular screen recording package is TechSmith's Camtasia and Snagit.
Somewhat pricey but well worth it when attempting to show software behavior to developers, etc.

DannyT - Thanks for sharing your model.

I also made a Hypershot render using their Kitchen HDRI. This is their low resolution version of the HDRI, so the background environment is not a sharp as it should be.

Using my quad-core PC, the "real time" image was instantaneous (and could not see a difference compared to the final render). I increased the quality settings quite a bit for the final render (not that it made any noticeable difference) and produced the attached render in 40 seconds. With default quality settings the final render took 6 seconds.

Hi Pilou,

> Seems there is a little error ;)

Yeah it looks like a bug in the filleter when trying to handle sharp corners touching a smooth surface right at the seam area of the smooth surface.

Unfortunately that's not an easy area of code to work on fixing up, it will probably be a while before that bug can get fixed.

In the meantime since that object is symmetrical it looks like there are other fillet areas that were created correctly that can be rotated and trimmed into place to fix that one little spot if you want to correct the error.

It's awfully hard to see that little spot in the rendered model though.

- Michael
