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

You fix an angle theta to which you want to rotate the points....and make Rotation matrix and multiply all the points with that rotation matrix.

Thank you, Dr.Sivia it is good information but I need to project objects to the any plane. your infors are rotated the object. I think it can't apply my problems. Anyway, thanks a lot. Hope to here another information from you
