标题:Gnomon工作坊——构建3D环境的有效技术
信息:
构建3D环境的有效技术
提示纽克,克拉丽斯,胡迪尼,速度树,玛雅和更多詹姆斯A.J .米勒

在这个由梦工厂动画公司的环境艺术家James A.J. Miller主持的3小时研讨会中,学习各种经过行业验证的高效技术来创建一系列3D环境风格。


工作坊首先展示一个沙漠环境中的大型3D城市环境。这种类型的场景为詹姆斯提供了一个很好的机会来涵盖三平面材料的重要性,看看houdini的地形工具,看看建模拍摄的要求,以及在克拉里斯散射。这就完美地把事情引向了纽克的AOVs,詹姆斯深入解释了AOVs是什么,以及艺术家如何利用它们。他演示了如何安装小发明,以及在返回拍摄和完成合成之前,何时在Nuke中使用aov的最佳实践。

接下来的部分在拍摄工作的间隙,介绍了摄影测量学在三维环境构建中的主题,以及如何有效地使用它。本演示使用Agisoft Metashape完成环境扫描。

接下来,James打开SpeedTree来遍历他的“Mothertree”镜头,该镜头使用了新的SpeedTree for Clarisse插件。此外,他还使用houdini来营造气氛,这可以被带回到克拉丽斯的场景中,以增加冲击力和真实感。

接下来,研讨会详细介绍了James在制作中经常使用的一些顶级技巧、诀窍和快捷方式,以加快建模和纹理处理速度,尤其是对于城市环境,最终目标是构建一个利用Clarisse中应用的所有纹理资源的场景。这个项目然后被用作詹姆斯最后一个镜头的发射点:“棚户区。”The Gnomon Workshop – Efficient Techniques for Building 3D Environments

这个工作坊提供了一个很好的机会来学习如何使用光路表达式来创建aov,甚至编写你自己的aov。最后一章着眼于如何处理重渲染,以及如何使用不同的投影技术,以帮助避免渲染超过你需要的三维。

Title: The Gnomon Workshop – Efficient Techniques for Building 3D Environments
Info:
Efficient Techniques for Building 3D Environments
Tips For Nuke, Clarisse, Houdini, SpeedTree, Maya & More With James A.J. Miller

Learn a variety of efficient industry-proven techniques for creating a range of 3D environment styles in this 3-hour workshop by James A.J. Miller, Environment Artist at DreamWorks Animation.

The workshop begins with a demonstration of a large 3D city environment in a desert setting. This type of scene offers a great opportunity for James to cover the importance of Triplanar materials, take a look at Houdini’s Terrain tools, look at modeling to shot requirements, as well as scattering in Clarisse. This then sets things up perfectly to lead into AOVs in Nuke, where James dives into an explanation about what they are, and how artists can use them to their advantage. He demonstrates how to install Gizmos as well as his best practices for when to use AOVs in Nuke before returning back to a shot and finishing off a composite.

The proceeding section takes a break from shot work to introduce the topic of photogrammetry in 3D environment building, and how to use it effectively. This demonstration walks through an environment scan using Agisoft Metashape.

Up next, James opens up SpeedTree to walk through his “Mothertree” shot, which makes use of the new SpeedTree for Clarisse plug-in. He additionally animates atmosphere using Houdini, which can be taken back into the scene in Clarisse for added impact and realism.

Moving on, the workshop details some of James’s top tips, tricks, and shortcuts that he uses regularly in production to speed up the modeling and texturing, particularly for city environments, with the end goal being to build a scene that utilizes all of the assets with textures applied in Clarisse. This project is then used as a launching point for James’s final shot: “The Squatter Village.”

This workshop offers a great opportunity to learn how to create AOVs and even write your own, using Light Path Expressions. The closing chapter looks at how to deal with heavy renders, as well as how to use different projection techniques to help avoid rendering more than you need to in 3D.
