MATLAB - How to project an sphere/hemisphere to any planes?

I have objects as a figure attached. I want to project objects (blue color and small red color) to plane (yellow color) follow perpendicular.

I can project object to coordinate plane (oxy, oyz, oxz) by command: surf(x,y,0*z), surf(0*x,y,z), surf(x,0*y,z). How to project to any plane?

Thank
