Street Lamps!

Posted by Zabot on 2 July 2016 in English (English).

Why is it night time? Here’s a quick update, street lamps are a thing now. There are 31 separate light sources being rendered in this scene, a total of 113 in the whole scene. The performance is much better than I had been expecting, even after that many lights, there is no significant slow down on my GTX960, even without optimization. Nonetheless I am still implementing the technique I mentioned earlier in the week to improve performance on more consumer grade graphics cards. You can try it out by adding a bunch of highway=street_lamp nodes to a local map file and viewing it with the dev build. Right now due to memory constraints, you can’t have more than 128 lamps, but I’m already working on increasing that.
