Lighting newb?

5 posts in this topic

I'm writing my game in Lua but I'm using GLSL for my shaders.

So I want to add a little light to my game, but I have little to no knowledge about 2D or 3D lighting. Specular lights, normal maps, ambient occlusions..all that stuff, I have no idea how any of it works.

So before diving into anything, I thought I'd ask if anyone had any good articles about delving into the matter, or a set of articles that explain the theory well. My game is in 2D and the end result that I would like to achieve is something like this:

or this:

Any help, general tips and links would be appreciated. Thanks!

Even if your game is 2d, the math behind this kind of lighting is 3d. I would recommend the book [url="http://www.amazon.com/Real-Time-Rendering-Third-Edition-Akenine-Moller/dp/1568814240/ref=sr_1_1?ie=UTF8&qid=1349161532&sr=8-1&keywords=real+time+rendering"]real-time rendering[/url] for all the basic stuff, it is really good and will explain all you need to know about normal mapping.

Another vote for real-time rendering here, it's a must-have book for any graphics programmer, beginner or pro

Wow, that book looks awesome. And it's written by the people that made LBP? (Or is that just a happy coincidence that the character is on the cover? :P)

I'll definitely check it out. Anymore links/articles would be appreciated! Thanks!

I'm not sure whether any of the authors actually worked on LBP, I know Naty Hoffman has worked for SCEA for a while but I have no idea which projects.

I have a whole bunch of graphics articles lying around, but they're mostly for very specific topics
