Tilt a 2D image within a 3D space?

Hello, The images i have need to be "tiltable", which means, Id like to display them and then via mouse reposition the camera/ Viewpoint. I do not want to rotate the image, but only change its elevation (?I guess?). Im thinking of using the view function.. if that is correct, would somebody be able to give me an example of how to do this? Greetings,nad

hi, the question is unclear, I am not a native speaker but tilting and rotating is the same no? There is an m-file in the file exchange for rotating in 3D around an axis, I saw a link in a post yesterday,
if you want to create new viewpoints on a scene you actually need three day information, in my opinion, on less you are speaking of rectification like in stereovision? e.g. If you do not have 3D data rotating your graph will not help rJ

Hallo Jürgen, dem Namen nach her würde ich Sie als Deutscher einstufen? Well my image is only 2d, but i still want to tilt it. rotating is mostly used in terms of tilting it to the side, within x and y. This image however should be rotatable to the back(>>z), also nach hinten kippbar.

Hi no, it doesnt help so far. I guess I need to plot somewhat of an horizontal axis in the middle of the image. Then get the image to rotate around that. Is it clear what i am asking for though? The image should stay 2d, it has a reason, its supposed to be an effect later on. Since this is for medical imaging... maybe another idea? Thanks so far!

This file exchange submission should let you wrap an image to any flat surface: http://www.mathworks.se/matlabcentral/fileexchange/3777-tcolor-a-fast-pcolor-that-likes-rgb-images
Then you can use the regular zoom and rotate functionalities of the ordinary matlab figure window. Further, you should have no problems modifying this function to also include a vertical component of the surface you want to wrap the image onto.
