Attached are some OpenGL renders, Phong verses SSAO. The SSAO code was provided by the authors of The Blue Book (http://www.openglsuperbible.com/).
Which do you like better?
Phong versus Screen-Space Ambient Occlusion (with source code)
The first one (I'm assuming it's Phong) looks better, but why not combine both?

Thanks for your opinion. Yes, it would look good combined.
¿Porque no los dos?
Hey, spanish guy !
Multiply them together
We have to say it's not physically correct to multiply them because it's an ambient value but it's the common trick to multiply after the lighting.
That will result to have the ambient occlusion visible even if the zone is lighted but it's an artistic value.

Yeah but nothing about SSAO is physically correct, it's an aesthetic hack. What we want is hemispherical occlusion applied to a GI light contribution, but here in the real world...

Was gonna say this. AO is a hack, SSAO is a hack of a hack.
I quite like the one on the right. I think the highlights look better on the left but the darker areas look better on the right. Which I suppose is their respective strengths. The right one makes the various features stand out more in my opinion.
