vb_get_proj_point

PURPOSE ^

Get marker 3D coordinate from the projected 2D-image by mouse click

SYNOPSIS ^

function [Vp, Xp, Yp] = vb_get_proj_point(V,X,Y)

DESCRIPTION ^

 Get marker 3D coordinate from the projected 2D-image by mouse click
   Vp = vb_get_ref_point(V,X,Y) 
 --- Input
 V : 3D coordinate
 X : X-coordinate in projected 2D-space
 Y : Y-coordinate in projected 2D-space
 --- output
 Vp : selected 3D point
 Xp : selected X-coordinate
 Yp : selected Y-coordinate
