Apologies...didn't follow the whole thread.

Mark,
It's not hard to round to integers. The problem is that Rev works with
integers for its rotation algorithm and therefore corrupts the
graphic in
the process.

While I agree that it would be handy if the engine could accept non-
integers for graphic points, a simple function to round a list of
4000 or
so points to integers took 34 milliseconds on my 1.5Ghz PB
G4...hardly
onerous in either execution time or coding effort.
Cheers,

#13) General flakiness. I would definitely say revCrumplePoly is a
better
name for the revRotatePoly command. Is there any situation where
revRotatePoly could be useful? Not if it does this. Totally
bugged. (I
suspect the reason why is that Rev doesn't have fractional
coordinates?
Could such a limitation really result in such dramatic
distortion? If
this
is the case, then Rev should store fractionals, but render to
integers.)
Here, here. I have been promoting fractional coordinates for
graphic
points for some time. Try the following handler:
on mouseUp
set the loc of me to 200.6,200.4
put the loc of me into msg box--reveals 200,200
set the points of grc 1 to 100,100 & cr & 200.4,200.6
--There is no evidence of the line graphic
-- The fractional point is not truncated but interpreted as a
blank
line.
end mouseUp
RR will accept fractional coordinates for controls (it truncates
the
coordinates) but it will not accept fractional graphic points.
You don't get an error message and no feedback that the problem
lines in
the fractional coordinates.
Problems arises when the graphic points are computed; the
programmer may
not realize that the points are fractional or that RR will not
accept
fractional points. Any point with a fractional coordinate is
interpreted
as an empty point and therefore a discontinuity.
It has been a while and I forget the details, but I think there was
support for this change in RR; so far no implementation.
