linear_combination (
        a,
        u,
        b,
        v,
        )

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

integer_variable_value ( v,  default=None )

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.

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.
