Off Topic (sort of) LWCAD 3...

I've ready stated my wishes that Michael would add similar "realtime 2d curve booleans" to MOI similar to LWCAD:
http://www.wtools3d.com/swf/tutorials/RTboolean/RTboolean.html

Now the boy done went and added realtime 3D booleans - oh the pain!
http://www.wtools3d.com/swf/online_help/LWCAD_30/teaser_scene/teaser_scene.html

At first watching the video I was like bloody-ell? This don't look like much?!!

I do sorta like that new user coordinate widget thingy though! (May be some ideas there for Michael!)

But by time it got near to the end of the video with the realtime object booleans, my socks started to loosen up and fall down (precursor to socks getting knocked off perhaps??)


Anyway, I guess my question to Michael would be do these features seem like something feasible within MOI? (With Michael's own twist of course!)

I can imagine the calculations required to realtime boolean something must be amazing - I'm assuming LWCAD is working in the polygon domain which may simplify the calculations a lot.

Though for simple boxes and such, even in NURBS perhaps it's not that hard? But for "big" assemblies and crazy shapes, I'd imagine the realtime boolean speeds would go WAY DOWN?

However I do believe these tools are designed to be used as shown; creating new (complex shapes) from booleaning simple input shapes...

Anyway, I can't help but wish some of this realtime boolean stuff was in MOI...
(I guess I'll also be saving up my $99 for LWCAD 3 upgrade when time is due :-P )

Hi Will, it is definitely an less intensive calculation process working with polygons rather than NURBS. The whole process of calculating a smooth intersection curve between 2 curved surfaces is pretty involved.

I am hoping to support a deeper history function in the future, which should generally allow you to do things like edit shapes and have boolean results update in response to your edits, stuff like that. But I want to make it a very general purpose mechanism that handles all kinds of modeling functions, not something that is just specifically baked into just boolean commands and nothing else.

It will probably take me longer to make that kind of fully general mechanism, but I think it will pay off a lot more in the end.

Hi Will,

Looking at those vids, it looks similar to the "Dynamic Geometry" currently in Hexagon.

Daz has dropped the ball with Hex so bad, I haven't bothered to reinstall it!

They then added salt to the wound by breaking the shortcut keys for changing the SubD levels and adding "sculpty" stuff for Second Life (whatever that is...)


Of course MOI is the tool I enjoy modeling with the most for getting concepts and forms out quickly so I can't help but wish tools like that were slated for it...

Still waiting for Newtek to give Modeler some love - LWCAD is the only tool that makes Modeler's outdated UI usable for me (well that and VertiBevel) - I just find myself using Silo the most when I'm at the poly level which lacks LW's precision when doing mechanical models.

Hi Will,

>>Daz has dropped the ball with Hex so bad, I haven't bothered to reinstall it!

I am no great supporter of Hexagon (although I do use the software now and again), I was just giving a comparison to what I viewed on the vids.

>>They then added salt to the wound by breaking the shortcut keys for changing the SubD levels and adding "sculpty" stuff for Second Life (whatever that is...)

I looked at the latest version of Hexagon (2.5) but simply went back to 2.2.
The "second life" I do not know, simply because I have not tried to find info, but would say, I have no interest at this time, and would prefer a way to remove that tab in 2.5

>>Of course MOI is the tool I enjoy modeling with the most for getting concepts and forms out quickly so I can't help but wish tools like that were slated for it...

I do model more with hard surface, so MoI to me is what I want, but there will always be a "Could it do more" type of concept from me,.. really more a fact I would like MoI to go a lot further into the CG community.

Well the realtime booleans are part of the realtime Truespace engine for
the new beta update od 7.6 too !
See realtime boolean from Roman Ormandy (Caligari)
http://forums1.caligari.com/truespace/showthread.php?t=893
Work pretty nicely !
