Function Documentation

void msm_reflect_shape_along_x	(	const msm_points &	points,
		const vcl_vector< unsigned > &	sym_pts,
		msm_points &	new_points,
		double	ax
	)

Reflect points in the line x=ax, then re-number.

On exit, new_points[i] = points[sym_pts[i]] reflected in x=ax

Parameters:

sym_pts[i]

defines the point symmetric with point i Renumbering necessary for symmetric shapes. For instance, if reflecting a face, the left eye becomes the right eye. This would mangle a model, so we renumber.

On exit, new_points[i] = points[relabel[i]] reflected in x=ax
