ginputSurface

Graphical input from mouse on 3d surfaces

Works similiar to Matworks ginput function

• Supports surfaces that contain nan and inf
• Allows zooming, panning, 3d rotation, and point query between or prior to point selection

Selected will be the part of the surface that the viewable sightline intesects with using interp2. The funciton will not return parts of the surface outside the visible axis

Known limitations:

• if the sight line to the cursor intersects with the surface multiple times in the span of less than a pixel the returned value may be errenous.

Example:

[X,Y,Z]=peaks(30);

surf(X,Y,Z);

[x,y,z,b] = ginputSurface(X,Y,Z,3);
