Techsoft 3D, the HOOPS people, are showing us the kinds of advanced visualizations that they make possible. Right now they are demo'ing a 3D section plane -- think of the three-sided corner of the room kind of shape, but transparent -- cutting through a 3D model. You see a rectangular cutout.
Randall Newton is asking why they created the 3D Adobe integration -- was it market-driven? They think 3D PDF will become more important in the years to time, and so they are anticipating demand in the future. I thought I got a hint that this may be driven by Adobe.
Well, something that's got to be fixed the 3D PDF display speed. The demo jock apologized, "It's Acrobat, not ours" as the 3D model failed to rotate inside Acrobat Pro. It's that sluggishness that has caused me to ignore 3D PDF.
ADTdirect
Vadim Kosarev of the ODA is demoing the architectural extension to the the ODA's DWG "platform", called ADTdirect. This lets you write custom architectural applications -- not new, something that's been around for quite a few years, but relatively unknown. The ODA wants to change that lack of awareness.
The demo architectural app shows the capabilities of ADTdirect. Some of the features we are seeing include:
- 3D grips (eg, make walls longer, wider, and taller)
- self-cleaning walls; slabs (floors); single- and double-angle roofs; doors and windows that snap intelligently into walls
- interactive 3D rotation
- window styles change all windows instantly
- all types of stairs, with grip editing. If railing entities are attached to stairs, they react as stair parameters are changed.
Facet Modeler
The ODA's facet modeller uses b-rep [boundary representation] technology (AECGe class name). It is currently used by the ODA's architectural and civil engineering apps, but could be used elsewhere. It supports primitives, Booleans, revolution, section, cut with extrusion, and so on.

(I just noticed that the government of Portugal is running tourism ads on this Weblog. I am guessing that Google AdSense is reacting to my references to Holland.)
