Thread Subject: Rotation with angular velocity

How could I rotate a sphere with a known steady angular
rotational velocity?
And moreover how could be imaged all the movement, from the
begging to the end?

Thanks

if it is a 'known steady' angular velocity there is no
beginning and no end.

Something like this?

[x,y,z]=sphere(20);
h=surf(x,y,z);
set(gca,'plotboxaspectratio',[1 1 1], 'dataaspectratio',[1 1 1])
for i=0:20;
   set(gca,'view',[i*15, 30]);
   drawnow;
   pause(1);
end

This causes a rotation of 15 degrees in azimuth between
positions, with new positions at a rate of 1/second.

Unfortunately there's some autoscaling going on as the
figure rotates, which I don't remember how to turn off.

Do you mean make a movie of the rotation?

Aha!

It was driving me crazy trying to figure out what property
I was missing with calls to SET. Turns out that I was
missing setting 'CameraViewAngleMode' to 'manual'.

The documentation claims that stretch-to-fill is turned
off if you set any of 'CameraViewAngleMode',
'PlotBoxAspectRatioMode', or 'DataBoxAspectRatioMode'
to 'manual', but that's not true. I had the latter two set with
no effect on the behavior. This may have changed in some
recent release because I don't think I ever knew about
'CameraViewAngleMode'.
