[Chromium-dev] Query: SPU development and Bucket Information?

[James S. <arr...@gm...>]

I have a few questions.

What do the fields in the TileSortBucketInfo structure mean? I
understand the meaning of the hits data member, but what are the
pixelBounds, objectMin and objectMax data members for?

My second question is, can I SPU change it's "super" at run time? For
example, lets create a SPU with a NOP SPU as it's super, but later I
want to change it to a passthough SPU. Can I do this?
What would be the technique?

Thank you for your time,

Those are the bounding boxes for the object we're bucketing in object 
coords and in window coords.

I don't think that's possible.

However, the 'apichange' SPU shows how to change GL functions on the 
fly.  Maybe that'll help.
