[Cdk-devel] y coordinate orientation - the saga continues

[Miguel <mt...@mt...>]

Peter,

I went to make the 'small' change to Jmol ... and now I am confused :-)

>>>RasMol/Chime render the positive y axis going down (and positive z
>>> axis
>>> going away from the user and into the screen)
> Agreed

RasMol has the following
 -positive X goes to the right
 -positive Y goes down
 -positive Z goes away

Of course, when I flipped the y axis then the mouse behavior was backwards
... so I fixed that.

Then I tested the 'rotate commands' ... and they were broken too. So much
for my 'simple' change :-)

That got me wondering about the RasMol 'rotate' command

However, when you say:
 rotate y <degrees>

It is actually rotating as if the +Y axis is pointing upwards ... at least
that is what it looks like to me.

rotate x <degrees> & rotate y <degrees> behaved as I expected.


Now my brain is spinning ... but I don't know which axes it is spinning
around :-)

Please advise.


Miguel
