Combination Constraints of Multiple Fields for Implicit Modeling of Ore Bodies

In this paper, we introduce combination constraints for modeling ore bodies based on multiple implicit fields interpolation. The basic idea of the method is to define a multi-labeled function that combines different sub-implicit by operations, including intersection, union and difference operators. contribution paper resides in application more general with rules bodies, such geologist can construct honoring geological relationships flexibly. To improve efficiency surface reconstruction, pruning strategy used avoid unnecessary calculations hierarchical bounding box operation tree. Different RBF-based methods are utilized study cases bodies. experimental results several datasets show useful reconstruct surfaces mineralization involving fields.
