在本教学中我们将学习一个在实际电影工业特效制作过程中被证明可行的方法，这个新的技术能够在常用的粒子控制系统不起作用的情况下被正常使用。很多教学在粒子被生成后就结束了。Martin将告诉大家在仿真运算完成以后粒子可以用来做什么，他为大家介绍了一种典型的方式，那就是将粒子特效的结果给到合成团队，用于进一步的修饰。通过本教学你将学习到一个视觉特效专家所需要掌握的知识，还有如何在最终期限前得到完美的结果。
cmiVFX has released their newest lesson offering another glimpse into magical world of visual effects. The flows of power are often visualized with streamers of light chaotically traversing across the scene. How does one create chaos but also maintain the control a director will require? In this lesson we will teach one way this is done in a production environment. The workflow offered here is tested and proven effective within the film industry. This new, exclusive effect technique can succeed in scenarios where conventional particle control systems fail. Additionally, many lessons stop with mere particles in place. Martin Sawtell will teach you one way in which those particles may be used after the simulation is done. Martin answers the question, "Particles are simmed, now what?". He demonstrates a typical way to pass the results of a particle effect on to the compositing team for further refinement. This courseware will give you a clear idea of what is required of a VFX professional and how excellent results are achieved under the pressure of a real deadline.
This video introduces viewers to the powerful world of VOPs within Houdini, and how it can be used to direct particles via it's point cloud features. Exploring VOPs implementations in shading & rendering, geometry and POPs it presents an entire workflow that brings them together to provide you with an intuitive way to control particles. Central to this workflow is the process of developing a "point cloud advect" Digital Asset that can be re-used in any particle system- allowing the user to push particles around with arbitrary geometry that could come from SOPs, another sim or even a Mantra render. |
