show image in 3D customized meshgrid

hello everyone,

I want to display image in customized meshgrid in 3D space.

a) I defined xgrid and ygrid which is the position in z = 10 of plane and I want to display the image (the size is the same size as the image and I want each pixel will be one square of the grid)

       xgrid = linspace(Xfrom,Xto, width);
       ygrid = linspace(Yfrom,Yto, height);

how can I display it in 3D space and in the position I want?

b) I want to ask generally if I would like to display image in other way than plane (for example in sphere) can I define sphere in meshgrid and than display the image? (assuming of course that each square in the grid is one pixel and the size is match)

I hope the question is clear
