I understand you would like to transform the position and rotation of a sphere based on data from a camera.
You can use an hgtransform object to apply a transformation to one or many graphics objects in unison. Using an hgtransform in your project could work as follows:
- Create your sphere
- Create an hgtransform object
- Make the transform the parent of the sphere graphics object
- Create a transformation matrix using makehgtransform based on your camera data
- Set the transformation matrix as the 'Matrix' property of the hgtransfrom
- Update the figure by calling drawnow
- Repeat steps 6-7 as the camera moves and rotates.
The "Transforming Objects Independently" example from the hgtransform documentation can help you get started. It can be found at the follow link:
