linear_combination (
        a,
        u,
        b,
        v,
        )

Return vector au + bv where a, b are scalars.

place_marker_at_mouse ()

screen_axes ( xyz,  object_xform )

Return vx, vy, and vz screen vectors in object coordinates. The vx vector is scaled so that one screen pixel displacement in x is equivalent to an object coordinate displacement vx at the given xyz position. The vy vector is scaled likewise. The vz vector length is set to equal the vy vector length.

        )

Return vector au + bv + c*w where a, b, c are scalars.

pixel_size_at_midplane ()

place_marker ( xyz )

line_vrml (
        xyz_1,
        xyz_2,
        rgba,
        )

Return VRML for a line connecting two points.

apply_xform ( xform,  xyz )

close_model ( m )

Check if model already deleted before trying to close.
