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

So, no I am not German, :-) rather Belgian, close but no cigar :-) => Does the fucntion that Matt proposed do what you need?

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.
