Hi there,

with each new release I keep changing the
default btTransform contructor to this:

btTransform() { setIdentity(); }

may I suggest this as a feature ?

Having the default constructor set the identity will add performance overhead which other programmers may not want.

i understand, though I would consider instantiating
a btTransform a non-time-critical operation.
Having to set the identity after instantiation
would give the same overhead, and is normally
expected if the transform is subsequently used
for multiplication,

irony though that I've just written 3 functions
in which I had to fill a just-instantiated transform
with other values than Identity personally, I don't
mind the overhead, but setting the identity on
construction with a (static) identity tranform works fine too.
in all, my point is moot.
