[vwnc] 3D simulation

3D simulation

Dear Smalltalkers,

could you give me some ideas about 3D imaging and simulation in Smalltalk, e. g. for technical or medical solutions. Think scanning data from different devices need to be synced, processed and displayed with the ability to rotate, slice etc. in arbitrary ways interactively.

Are there any solutions in Smalltalk that one could use as a starter?
Or: are there any at all?
Which (external) libraries would you suggest?
Which kind of database would you suggest: OO or RDBMS?

Any pointers welcome!

TIA
Helge

An interesting problem area. I'd think Smalltalk would be ideal for it,
though I'll admit some bias in that area. :-)

I haven't used it, but there is Jun. I suspect that it's more on the
displaying 3D side than the manipulating 3D data side, but could still
be useful.

This sounds like an area where you might want deep hierarchies of data,
or other structures that don't fit easily into a table structure, so I'd
go with an OODB. GemStone would be ideal. I'll admit some bias in that
area as well. :-D

Regards,

-Martin

Re: [vwnc] 3D simulation

At Smalltalk Solutions 2007, there was a presentation on a 3D body
motion simulation package written in VisualWorks. I attended the
presentation and I remember it seemed very good. See here:

Oh, yes, this looked good.

Re: [vwnc] 3D simulation

We just do 2D , but we use :
- SIXX for object network storage (sorry for Gemstone) : the great
thing is our data model evolved a lot and SIXX just ignores missing or
added instance variables, and ignores hierarchy modification as well
- home made DXF reading and writing, but Jun has some stuff for that.
DXF is widely used in CAD, and allows to import complex designed forms

We looked at OpenGL but discussing with Michael Lucas-Smith, it
strongly depends on your video card, which makes it uneasy to
distribute.
Is there any general framework for simulation ?

Re: [vwnc] 3D simulation

In reply to this post by Nowak, Helge

If someone takes the trouble of interfacing Smalltalk to OpenCascade it would be most appropriate for more intense CAD kind of imaging and simulations.

Jun is OpenGL but from my experience of CAD not adequate enough for intensive rendering operations more in terms of performance and quality of rendering with anti-aliasing to the extent open-cascade engine can do.

Would be interesting stuff to extend OpenCascade to Smalltalk VW.. or generic Smalltalk if possible to keep the code portable and usable through all dialects.

Re: [vwnc] 3D simulation

There is a far more up to date OpenGL interface in the public store - you can visit Michael's blog for details on it:

http://www.cincomsmalltalk.com/userblogs/mls/blogView

It also doesn't suffer from being GPL...
