Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To generate a model whose feature on the sight of an object is reflected on a form and whose appearance is natural by specifying a part which requires correction based on two-dimensional photographing information of the object and generating the form model which is locally emphasized. SOLUTION: A data processor eytracts the area of a specified face element from a two-dimensional picture which color picture data shows. Eyebrows and pupils in the three-dimensional form model specified by form data are set to correction object parts Up and they are deformed, for example. In deformation, a mesh M vertical to a camera eye is projected on the correction object part and a correction vector (v) is calculated with a position on which a lattice point is projected as a sampling point (p). Then, the intersections (q) of the mesh M and the outlines of the correction object parts Up are obtained and a curve surface passing through the tip positions p2 of the correction vector (v) and the outline points (q) is obtained.  The curve surface and the original three-dimensional form model are synthesized and the correction object parts Up are substituted for the obtained curve surface Up2. Thus, the positions of the pupils and the eyebrows are expressed by the forms.

When the reaction temp. is kept lower than 1100 deg.C, the conversion efficiency to silicon dichloride and silicon trichloride is lowered, and the reactor material and heat economy are disadvantageously affected at >1300 deg.C. In addition, metallurgically obtained silicon is used as the raw-material metallic silicon, and the particle size is preferably controlled to 150-300mu.
