Lightning Fast Hidden Line Rendering in MicroStation CONNECT Edition Update 2

MicroStation CONNECT Edition Update 2 we introduce a new and much faster, multi-threaded Visible Edges processing engine which will take advantage of all available CPU cores.

Benchmark testing has shown very significant improvements in hidden line processing times.  You will see enhanced performance in these operations:

  • Export Visible Edges
  • Merge Visible Edges
  • Cached Visible Edges
  • Non-Raster Printing

Here are some initial reactions from MicroStation users who have been evaluating the upgraded Visible Edges Engine:

“On first testing of the Visible Edge engine I was taken aback at the speed at which it worked. The ability to browse and view models and dynamic views without lag and at the speed you want to is invaluable in drafting and review time and removes a frustration experienced by users.”  - Duncan Gammie, Cad Manager, LDS-Uk

Here is an example of the performance improvements we have measured*

 *Tested dataset: building project, 360mb, tested on an Intel(R) Core(TM) i7-4910MQ CPU @ 2.90GHz with 32Gb of RAM

Because of the way the geometric calculations must be performed, which precludes a multi-threaded approach, there is currently no significant improvement in Visible Edges calculations when "Exact" mode is selected along with "Calculate Intersections".
