Title: Dynamic lighting in a 2d game Post by: kvisle on November 02, 2013, 10:37:49 AM Hi!
I don't post here much, so you have probably not seen me before - I'm working on my own game, using my own engine written in OpenGL. The game is all in all 2D, all my mechanics and physics are in place - but I was wondering "wouldn't it be cool to add dynamic lighting in the mix?". So now I'm pondering how I could implement this. I've been searching for what techniques will implement this, and I'm not yielding any good results - I may be bad at searching, I don't know. The idea I have in my head, is that for each fragment in my lightmap, I will need to cast a ray towards the light source(s), and change the value according to if it's lit or not. This will definetely work - but I worry that doing this on my entire full screen 1080p game every frame won't be a tad bit expensive. I've decided to ponder on this problem for a while, before I go on and implement it - there are still a lot of other things to do in my game, so it can wait. But while I do so, I thought I should try ask someone here. Does anyone have any experiences doing this? Any example implementations to show to? /Trygve Title: Re: Dynamic lighting in a 2d game Post by: Christian Knudsen on November 02, 2013, 11:14:02 AM http://forums.tigsource.com/index.php?topic=18942.0
