迪斯尼动画电影《冰雪大冒险 Frozen》冰雪模拟制作解析 - Making of Disney's Frozen Snow Simulation





雪是一个具有挑战性的视觉模拟自然现象。虽然图形界曾认为积累的雪，雪动力学动画和渲染还没有完全解决。此外，现有的固体和流体技术有困难生产令人信服的雪结果。具体而言，湿的或致密的雪，同时具有固体和流体状的性质难以处理。因此，本文提出了一种新颖的雪地仿真方法，利用一个usercontrollable的弹塑性本构模型集成了混合欧拉/拉格朗日材料点，方法。该方法是基于连续体，它的混合性，使我们能够使用常规的笛卡尔网格自动处理自碰撞和断裂。它也很自然让我们得出一个基于网格的半隐式的整合方案，有空调拉格朗日颗粒的数量无关。雪现象，包括各种复杂的角色互动，我们证明了我们的方法。
Snow is a challenging natural phenomenon to visually simulate. While the graphics community has previously considered accumulation and rendering of snow, animation of snow dynamics has not been fully addressed. Additionally, existing techniques for solids and fluids have difficulty producing convincing snow results. Specifically, wet or dense snow that has both solid- and fluid-like properties is difficult to handle. Consequently, this paper presents a novel snow simulation method utilizing a usercontrollable elasto-plastic constitutive model integrated with a hybrid Eulerian/Lagrangian Material Point Method. The method is continuum based and its hybrid nature allows us to use a regular Cartesian grid to automate treatment of self-collision and fracture. It also naturally allows us to derive a grid-based semi-implicit integration scheme that has conditioning independent of the number of Lagrangian particles. We demonstrate the power of our method with a variety of snow phenomena including complex character interactions.
