lighting

I'm trying to learn about dynamic shadows for 2D graphics. While I understand the basic ideas behind determining what areas should be lit and which should be in shadow, I don't know how I would "lighten" a texture in the first place.

Could you go over various popular techniques for lighting a texture and what (dis)advantages each one has? Also, how is lighting a texture with colored light different from using white light?

I'm a software engineer that's new to game programming so forgive me if this is a dumb question as I don't know that much about game engines.

Is there any difference between storing textures and baked lighting for environment meshes?

as seen on Game Development - Search for 'Game Development'
I assume that when texturing environments, one or several textures will be used, and the UVs of the environment geometry will likely overlap on these textures, so that e.g. a tiling brick texture can be used by many parts of the environment, rather than UV unwrapping the entire thing, and having several… >>> More
