3D plot problem

Drago Zarkovic — Fri, 05 Jun 2009 07:48:02 -0400

I made a 3D plot and set cameraposition and target so that only a part of plot is displayed. As soon as I try rotate3d it sets cameraposition so far from a plot that it is shown whole. In earlier versions of Matlab (7.1, 7.0) it was OK, but in 7.7 I have this problem...
"""""""""""""""""""""""""
figure(1)
plot3([-25 25],[0 0],[0 0],'m')
hold on
plot3([0 0],[-25 25],[0 0],'m')
plot3([0 0],[0 0],[-25 25],'m')
[Xosa,Yosa] = meshgrid(-25:25,-25:25:-25:25);
Zosa=Xosa.*0;
surf(Xosa,Yosa,Zosa,'FaceAlpha',0,'LineStyle',':')
set(gca,'CameraPosition',[5 5 5],'CameraTarget',[0 0 0],'CameraUpVector',[0 0 1],'CameraViewAngle',45,'Projection','perspective')
rotate3d
"""""""""""""""""""""""""""
I want camera to stay close...

Thank you in advance

When I call camera toolbar and orbit with it it seems to be ok, but rotate3d doesn't work. Is it posible to call camera toolbar comands by code?

I just found out that rotate3d function sets 'CameraPositionMode' to 'Auto' as soon as I rptate plot. Is it posible to override this?

Please someone help

Have you ever used the function view? Maybe that could help. For instance, if you like a view and want to save it, you say:

goodView = view;

Then, when you make another plot and want to use this good view, then you say:

view(goodView);
