Bifröst is a fluid dynamics engine for high-quality liquids in visual effects, combining the best of volumetric and particle solvers in one tool. This course offers an overview of the Bifröst implementation in Autodesk Maya. Using emitter, collider, accelerator, and liquid property nodes, Aaron F. Ross simulates a medium-scale liquid effect and stores it to disk as a cache. Rendering the surface at full quality requires generating an animated polygon mesh; for a convincing layered material, he shows how to extract Bifröst channel data such as Vorticity and apply it in a shading network. The course concludes with a look at the Aero Solver for atmospheric effects.
Topics include:
Understanding Bifröst
Analyzing the node structure
Emitting from a polygon mesh
Colliding with objects
Pushing and damping fluid motion with accelerators
Caching Bifröst simulations
Meshing liquid and exporting to Alembic
Shading with the Bifröst liquid material
Designing mental ray materials
Layering shaders with Bifröst channel data
Adding mist with an Aero simulation
Texturing an Aero material

Bifröst是一种流体动力学引擎，用于高品质液体的视觉效果，结合最好的体积和粒子解算器在一个工具。本课程概述了Autodesk Maya中的Bifröst实现。使用发射器，碰撞器，加速器和液体属性节点，Aaron F. Ross模拟中等规模的液体效应，并将其作为缓存存储到磁盘。以全质量渲染表面需要生成动画多边形网格;对于令人信服的分层材料，他展示了如何提取Bifröst通道数据，如Vorticity和应用它在着色网络。本课程最后将介绍大气效应的航空求解器。
