Parameter Processing in CAD Technology of Crystal Lighting

摘要

According to the complex features of crystal lighting, manual modeling and modifying for it may be difficult and complicated.Based on CAD for Rhinoceros platform , the key of software development is transforming the feature factors into parameter variables during the quick modeling of crystal lighting by CAD. This paper includes how and where to place crystals for linearly shaped, surface-type, body-type crystal lighting and the calculation methods of the size of crystals, design parameter interface and at the end takes the surfacetypecrystal lighting as example in order to realize parametric molding of crystal lighting through modifying parameter variable.
