move (Aero.Node) - Change node translation and rotation
Syntax
move(h,translation,rotation)
h.move(translation,rotation)
Description
move(h,translation,rotation) and h.move(translation,rotation)
set a new position and orientation for the node object h. translation is
a 1-by-3 matrix in the aerospace body x-y-z coordinate
system or another coordinate system. In the latter case, you can use
the CoordTransformFcn function to move it into
an aerospace body. rotation is a 1-by-3 matrix,
in radians, that specifies the rotations about the right-hand x-y-z sequence
of coordinate axes. The order of application of the rotation is z-y-x (r-q-p).
This function uses the CoordTransformFcn to apply
the translation and rotation from the input coordinate system to the
aerospace body. The function then moves the translation and rotation
from the aerospace body to the VRML x-y-z coordinates.
Examples
Move the Lynx body. This example uses the Simulink 3D Animation vrnode/getfield function
to retrieve the translation and rotation. These coordinates are those
used in the Simulink 3D Animation software.
h = Aero.VirtualRealityAnimation;
h.VRWorldFilename = [matlabroot,'/toolbox/aero/astdemos/asttkoff.wrl'];
copyfile(h.VRWorldFilename,[tempdir,'asttkoff.wrl'],'f');
h.VRWorldFilename = [tempdir,'asttkoff.wrl'];
h.initialize();
newtrans = getfield(h.Nodes{4}.VRNode,'translation') + 1.0;
newrot = getfield(h.Nodes{4}.VRNode,'rotation') + [.2 0.01 0.01 0.01];
h.Nodes{4}.move(newtrans,newrot);Limitations
This function cannot get the node position in aerospace body
coordinates; it needs to use the CoordTransformFcn to
do so.
This function cannot set a viewpoint position or orientation
(see addViewpoint).
