I am curious about information pointers on two subjects.

first I see that this years siggraph achievement awards went to two 
researchers that worked on the original paintbrush systems.  I am curious to
know how such systems doing smear,blur,blend and such.  I am also interested
to know what the original references are for that work.

second, I know that physicists do computer simulations of galaxies, globular
clusters, planetoid collisions and such.  These things I might call
particle system dynamics.  What are the basic methods of doing these types
of computations efficiently.  Is there a basic textbook or basic references 
but I am sure the field has really baroqued out with thousands of obscure
numerical methods.  I don't want to spend my life chasing them all down.
Just the facts.

Thanks
