This is the presentation I made for my Show&Tell at Inercia Demoparty 2008. It's an area portal visibility determination application I had made to get some know how in this fantastic technique.
This application loads an obj file I created my self with portal and geometric data, then, it prepares that geometric data for the visibility determination. In the end, it shows the results.
The presentation was 20 minutes long, I showed the application running, a PowerPoint presentation with a simple explanation of the inner workings and a session of questions at the end. The original PowerPoint presentation is in Portuguese and you can get the translated version as well. I still do not have any video, something I have to add lately.
