Hi Nike, There is many way to get shadows and the shadowing technique choice shall depend of your scene data. The two basic shadowing techniques are : - shadow maps ( image based ) - shadow volumes ( geometry based ) Shadow maps are very cheap and easy to implement but will works good only

Hi Alexej, Are you stuck using OSG-1.x?? You viewer example looks like it's from the 1.x era. Regardless though, when you have an event driver app the frame loop just ends up being part of paint call normally so this is where you'd do update. Personally I would stay a long way away from event
