Procedural Modeling of Elastic Aggregates based on Aperiodic Space-Filling and XPBD Simulation

抄録

In this paper, we propose a new method based on two existing methods for procedural modeling of common rice dishes and aggregates of natural objects such as salmon roe and shaved ice. One existing method, which is the most realistic but also the most time-consuming, uses full-length physical simulation to generate the aggregates. There are two steps: the shape and components specified by the user are used as inputs, the components fall under low gravity into the specified shape, and a full-length physical simulation from the initial state to the stable final state is performed using the XPBD method. This usually takes a few hundred frames. The other existing method is aperiodic space-filling. It has two steps. First, it requires components and shapes to be input by the user, and then it fills the specified shapes with components in a non-overlapping order. Each existing method has its own weaknesses; this paper introduces a new method that combines the advantages of the two existing methods, elastic aggregates based on aperiodic space-filling and XPBD simulation. We perform physical simulations to generate more realistic aggregates with parameters such as friction data input by the user.
