Concerning the python way to access body's geometry, I tried what you
suggested but when I do this

for i in O.interactions:
    if not i.isReal : continue
    if O.bodies[i.id1].shape=='Facet' or O.bodies[i.id2].shape=='Facet':
        print O.bodies[i.id1].shape, O.bodies[i.id2].shape

it seems like if the test is never true, which is not the case if I do the
test with the "real" id of the Facet (identify through the xml file for
example):

for i in O.interactions:
    if not i.isReal : continue
    if id.id1==FacetId or i.id2==FacetId:
        print O.bodies[i.id1].shape, O.bodies[i.id2].shape

But maybe I am in a dead end because, in fact, I would like to assign a
parameter to the identified bodies like this (remaining in the loop on
interactions)

O.bodies[i.id1].shape['diffuseColor']=(1,0,0),
O.bodies[i.id2].shape['diffuseColor']=(1,0,0)

and I get this message

SyntaxError: can't assign to literal

which means that I probably do not play with the right entity... Do you have
any advice? I am stucked...
