Never saw this, the CELL can improve graphics after all

for the first video :

1/ so are they using 6 SPE or all SPE ? EDIT : ok for all SPE !!

2/ sorry Dolla Dolla but,
this sentence :
"""so in total, 14 SPEs are doing raytracing to produce a 720p image with 4x supersampling. """
doesn't help me much to know WHAT IS RAYTRACING ?

 

It's a special kind rendering that makes things like reflections super realistic because it simulates how your eyes work in real life... I think. As opposed to regular rendering where everything is simulated from the point of light.

Raytracing is essentially shooting a ray out form every pixel on the screen to one or more light sources.  It's a very parallel and very math heavy process.

Rasterized graphics that you see in today's games use "translations" of the 3D coordinate plane to a flat 2D plane.  Once you place the object in your virtual 3D space, you apply filters and effects to the objects 2D representation.

Kasz216 is close in saying that Raytracing is basically like how your eyes work (but in reverse.)  Your eye accepts light coming from and reflecting off anything.  Raytracing is reversing that step and only rendering what your eye (viewport) can see [most of the time.]
