There is too much of a restriction in Xyzd.
I like Xyzd; I suspect that really is one of the secrets to the fast
rendering.
Actually, I would say that the Xyzd is causing more trouble than it is
worth. I added it relatively recently (1 year ago? 18 mos ago?).
At a minimum we can go back to storing the screen coordinates as 4
shorts.
That is an easy change that will increase the range and will not
increase
memory consumption for macromolecules.
So I'd propose:
a) in Atom.java, remove the z limitations.
b) in Xyzd.java, remove the two "guard/overflow" bits. They are NEVER
checked.
c) in Xyzd.java, remove the zero offset -- just store the int values
directly.
This then allows a range of -2^15+1 to 2^15-1 -- -32767 to 32767.
For an
800x800 applet, that will allow a zoom of 40, roughly.
If that is only going to give a zoom of 40 then clearly that is
insufficient.
I think this should be 40x, not just 40. yes?
