摘　　要：自然界中的物体通常采用图形和图像两种表达形式 ,它们在计算机中的描述则是采用两种不同的数据格式。特征建模是当前工业产品数字化建模的主要手段 ,但是目前的特征描述模式不能描述复杂的表观和非均质材质信息。提出一种图形 /图像融合的特征建模思想 ,可以有效解决这一难题。论文详细论述了基于图形图像融合特征建模的必要性和方法 ,并给出了几个应用实例。Objects in nature are usually presented by adopting two expression forms of graphics and images.They are described in computers by adopting two different kinds of data formats.Feature modeling is the major means in digitalized modeling for current industrial products.But up till now the pattern of feature description can not describe complicated appearance and information of non-homo geneous materials.This paper advanced a kind of feature modeling idea of blending graphics with images,which could resolve this problem effectively.The mecessity and method of feature modeling based on blending graphics and images were discussed in detail and several applied living examples were given out in this paper.
