Research on 3D Product Shape Merging Technology Based on Spherical Harmonic Map

Abstract: The 3D product shape innovation design has played an important role in product#br# styling design, which is an important way to improve the product competitivity. A new algorithm#br# to realize shape metamorphosis between two products based on Spherical Harmonic Map is#br# presented, which will generate several product shapes. Two 3D product shapes are firstly divided#br# by triangular meshes. Then the meshed product shapes are embedded to a unit sphere and generate#br# the embedding models, which have the same topological structure as their 3D product shapes. By#br# merging two embedded models, a corresponding relation between two shapes can be established.#br# The intermediate shapes between two products are easily generated with the linear interpolation#br# method. An experimental study is presented with merging two different mouse prototypes. The#br# result shows that the algorithm is adapted to the product shape merging, which will have a better#br# application prospect in innovation design of computer aided product styling.#br# Key words: product styling; 3D shape; spherical harmonic map; merging

Abstract: The 3D product shape innovation design has played an important role in product
styling design, which is an important way to improve the product competitivity. A new algorithm
to realize shape metamorphosis between two products based on Spherical Harmonic Map is
presented, which will generate several product shapes. Two 3D product shapes are firstly divided
by triangular meshes. Then the meshed product shapes are embedded to a unit sphere and generate
the embedding models, which have the same topological structure as their 3D product shapes. By
merging two embedded models, a corresponding relation between two shapes can be established.
The intermediate shapes between two products are easily generated with the linear interpolation
method. An experimental study is presented with merging two different mouse prototypes. The
result shows that the algorithm is adapted to the product shape merging, which will have a better
application prospect in innovation design of computer aided product styling.
