Applied Houdini是一个以电影生产项目级的高质量为标准的系列，由Steven Knipping创建，他目前是Lucasfilm工业光魔公司（星球大战：天行者的崛起，复仇者联盟，残局，海王）的高级FX技术总监。在Houdini中模拟制作彩色烟雾特效，体积烟雾效果，烟雾细节的制作，色彩的叠加，烟雾特效快速模拟渲染技术。Sparse Simulation模拟技术，利用Sparse Pyro求解器进行详细，多彩和快速的烟雾模拟。从使用粒子模拟开始，然后Sparse Simulation求解器帮助我们更快地获得高分辨率效果。介绍最常见的灯光类型以及它们如何与体积烟雾效果配合使用，然后我们可以通过材质设置进一步控制它们。我们还将介绍许多通用的体积渲染概念，以及如何将它们应用到Mantra，以交互方式更快地迭代，同时还可以实现高效高质量渲染。使用Houdini内置的合成工具对这些图像进行后期渲染处理，渲染生成最终效果图像。

CGCircuit – Applied Houdini Volumes III v2. Here it is, Applied Houdini Volumes III v2 – Rendering and Sparse Simulation! In this lesson, we’re going to talk about how to make a detailed, colorful, and fast smoke simulation by taking advantage of the Sparse Pyro solver. We’ll start by sourcing our smoke with a particle simulation, and see just how the Sparse solver works to help us achieve high resolution results faster. We’ll go over the most common types of lights and how they work with volumes, which we can then control further with material settings. We’ll also cover a lot of universal volume rendering concepts, and how we can apply them to Mantra to both iterate faster interactively, while also making effecient high quality renders. Finally, these images will be manipulated post-render with Houdini’s own compositing tools, to make our final images. Run better sims and understand more deeply how volumes are shaded and rendered today with Applied Houdini!
