Abstract—In constructive geometry, implicit blends with blend range parameters are important in constructing a complex surface because they limit the blend surface within specified regions and deform primitive locally after blending. However, because they behave like Max or Min blend in non-blending regions, their primitives always have similar sizes of subsequent blend surfaces when used as a primitive in sequential blends. To solve this problem, this paper proposes union blends that provide each primitive an additional parameter to adjust a primitive’s subsequent blending range in later blends; thus, primitives are able to individually adjust the sizes of their subsequent blends by varying the values of the additional parameters. In addition, a generalized method is proposed to develop the proposed union blends with C¹ continuity from an existing blend.
