Light probes

[Adversus]

Has anyone implemented these in irrlicht?

I'm talking about something similar to what Unity has.

I tried them. They are not worth if you have deferred lighting.

Still, you can use a lighting manager, and create your own system. Check the example 21 which is conceptually very similar. Research for spherical harmonics. and irradiance volumes and you can achieve very similar results.

light probes are mostly useful only in mobile phones or older hardwares.

Dunno what light probes are but do you mean this?

No, light probes are references for the lighting at specified places. When an object moves close to these light probes, they pick their lighting. But if you have deferred rendering, you can light the object with the deferred lights directly. Is a quick way to lit the objects without the need of deferred rendering,

Ahh i see so it a way to simulate indirect lightning then? or really just lightning made simple for mobile platforms

Light probes provide a useful way of getting local light information, just another way of managing large clusters of lights.

Not limited to only mobile platforms or older hardware, they can be used alongside lightmaps and other lighting methods for very good results, checkout some of the stuff Valve have been doing with different types of light probes

[Mel]

In fact, combined to a deferred renderer, it could provide a complete lighting solution. The light probes give the ambient lighting and the deferred lighting the difuse component.

even a linear gradient will works better than ambient light. and light probes are much better than a linear gradient

Shame no-one has done this. Would have been nice.

[Mel]

I have done them, but i don't use them any more ^^U

[Adversus]

No chance you're willing to share?

[Mel]

Hehehehehe... Good one...

Who knows where are those codes now... =_=U
