我们提出了一个代数框架，称为建设性体积几何（CVG），复杂的空间对象建模使用组合运算。通过利用标量场作为基本构建块，CVG提供了数学定义或基于采样或模拟数据集构建的对象的高级代数表示。它对无定形现象和固体物体进行建模，并描述物体的内部和外部。我们还描述了一个层次表示方案的CVG，和一个直接绘制方法与一致采样的新方法。这项工作已经证明了在一个连贯的建模方案相结合的各种图形数据类型的可行性。
We present an algebraic framework, called Constructive Volume Geometryn (CVG), for modelling complex spatial objects using combinational operations. By utilising scalar fields as fundamental building blocks, CVG provides high‐level algebraic representations of objects that are defined mathematically or built upon sampled or simulated datasets. It models amorphous phenomena as well as solid objects, and describes the interior as well as the exterior of objects. We also describe a hierarchical representation scheme for CVG, and a direct rendering method with a new approach for consistent sampling. The work has demonstrated the feasibility of combining a variety of graphics data types in a coherent modelling scheme.
