Method and apparatus for forming objects based on free-form curves and free-form surfaces from projecting nodal points and a series of points onto a patch |
摘要 |
In a method for forming free-form curves and free-form surfaces, the nodal points of the object to be projected and a series of points set on the object to be projected are projected onto a patch. Free-form curves are generated on the patch on the basis of the result of projection. Thereby, free-form curves of the geometry projecting free-form curves may be generated readily and with high accuracy on the patch and, further, the free-form curves may be used to generate a framing space, or a free-form surface.
