print_2d_coords

print 2D coordinates corresponding to a 3D point on a surface

print_2d_coords input.obj x y z

DESCRIPTION

print_2d_coords prints the 2D parametric coordinates corresponding to a given 3D world coordinate point on a surface object. The program finds the closest point on the surface to the specified (x, y, z) position and outputs the corresponding 2D parameterization coordinates.

This is useful for mapping between 3D surface space and 2D flat map representations.

EXAMPLES

print_2d_coords cortex.obj 10.5 -20.3 45.0
