Having spent a little time over the last few days with some of the work being done here at UNSW Built Environment with repect to bringing in Architectural models into real-time environments like CryEngine I had a quick browse through some videos on Autodesk Showcase.
Showcase takes data from packages like Revit and manhandles them into a semi-attractive real-time walkthrough or flythrough engine. There are some nice features like the sectioning and the expected features of floor/wall detection etc. That said it certainly doesnt have the audio, visual and emotional richness we are getting with the CryEngine Free SDK.
Being able to link Industry apps like Revit with the vanguard of visualisation tools would be a nice future for all. With PlayUp doing such a great job with Sketchup, the bar has been set and there is plenty of room to grow from there.
