Hey,
Im just curious what really goes into making a portal engine? Is it really simple as segmenting the level mesh, and the line picking sections with camera viewing angles and showing and hiding accordingly? Or is there something more such as using vector maths to speed up the line pick (heard that somewhere)?
I've come accross this article, any more help guys?
