Move camera position and target
camdolly(dx,dy,dz)
camdolly(dx,dy,dz,'targetmode')
camdolly(dx,dy,dz,targetmode,coordsys)
camdolly(ax,...)
camdolly(dx,dy,dz) moves
the camera position and the camera target by the specified amounts dx, dy,
and dz.
camdolly(dx,dy,dz,'targetmode')
uses the targetmode argument to determine how the
camera moves:
'movetarget' (default) —
Move both the camera and the target.
'fixtarget' — Move only
the camera.
camdolly(dx,dy,dz,targetmode,coordsys) uses
the coordsys argument to determine how MATLAB® interprets dx, dy,
and dz:
'camera' (default) — Move
in the coordinate system of the camera. dx moves
left/right, dy moves down/up, and dz moves
along the viewing axis. MATLAB normalizes the units to the scene.
For example, setting dx to 1 moves the camera
to the right, which pushes the scene to the left edge of the box formed
by the axes position rectangle. A negative value moves the scene in
the other direction. Setting dz to 0.5 moves the
camera to a position halfway between the camera position and the camera
target.
'pixels' — Interpret dx and dy as
pixel offsets. This option ignores dz.
'data' — Interpret dx, dy,
and dz as offsets in axes data coordinates.
camdolly(ax,...) operates
on the axes identified by the first argument, ax.
When you do not specify an axes object, camdolly operates
on the current axes.
camdolly sets the axes CameraPosition and CameraTarget properties,
which in turn sets the CameraPositionMode and CameraTargetMode properties
to manual.
Move the camera along the x- and y-axes in a series of steps:
surf(peaks)
axis vis3d
t = 0:pi/20:4*pi;
dx = sin(t)./40;
dy = cos(t)./40;
for i = 1:length(t);
camdolly(dx(i),dy(i),0)
