Exploded View Diagrams of 3D Grids

摘要

We present a system for creating interactive exploded view diagrams in generalized 3D grids. The primary difference between our approach and existing ones is that our technique neither requires geometrical information of the whole model nor any information regarding the relationship among model parts, instead our implementation depends on which grid cells are considered as object of interest, and which view angle to use. To achieve this, we introduce the Explosion Tree, a data structure closely related to a BSP tree, which supports the explosion view diagrams technique based on the relationship between disjoint convex polygons. In this paper we discuss the application of this technique to Corner-Point Grid which has been extensively used for geological modeling and flow simulation. All the data presented in this work consists of real data currently used in the industry.
