Brussels, Belgium
The single, biggest announcement in Bricscad V12 that has got everyone talking is direct modeling. Bricscad V12 now offers Variational Direct Modeling (VDM), which is something that was pioneered by LEDAS Corporation back in 2008. On Day 2 of the conference, Dimitri Ushakov, the CEO of LEDAS and Bricsys Technologies, Russia gave an overview of all the solids modeling technologies that have been in use over the past years. His presentation made the complex world of solids modeling technologies easy to understand by an MCAD layman (like me).
He began by giving a brief history of modeling technologies and followed it up with a slide which compared history-based and history-free (direct) modeling and then went to explain the differences between direct and indirect modeling.
VDM offers the best of both worlds. It offers the best of history modeling and pure direct modeling.
Dimitri Ushakov beginning the presentation by talking about the advent of Direct Modeling era.
He went on to explain a little about some of the early pioneers and implementations of direct modeling -
- SolidDesigner from CoCreate, the software division of HP in 1992, which eventually became CoCreate and is now Creo Elements / Direct.
- IronCAD from IronCAD LLC in 1998
- CADKEY from Kubotec in 1999 (now known as KeyCreator).
In the next slide, he showed some of the important milestones in the modeling world.
More technical details about the differences between the two modeling techniques explained.
Direct and Indirect modeling explained
Procedural vs Variational Modeling. As you can see from the slides, this was an extremely educative, informative yet simple presentation by Dimitri Ushakov.
"In direct modeling, data is not lost in translation. Dumb data can get talking again. For instance, data imported via SAT files", said Dmitri Ushakov.
This chart summed up the comparative differences between the three modeling techniques.
The next three slides show how the modeling techniques work and which one is be suited for you.
