Intro to PDG _ 8 _ Creating Wedges

Lesson and Project Files: sidefx.com/tutorials/intro-to-pdg/
Start off by creating work items using the Wedge TOP to represent the various city variations/wedges that you will generate. You can read attributes from TOPs into the Houdini scene to generate variations on the geometry.
谷歌翻译：
课程和项目文件：sidefx.com/tutorials/intro-to-pdg/
首先使用 Wedge TOP 创建工作项来表示您将生成的各种城市变体/楔子。您可以将 TOP 的属性读取到 Houdini 场景中以生成几何体的变化。

Intro to PDG _ 9 _ ROP Geometry Output

Lesson and Project Files: sidefx.com/tutorials/intro-to-pdg/
To cache geometry using TOPs, you can use the ROP geometry output to save the results of a node to disk. You can utilize work item attributes to ensure that each wedge is saved to a unique path.

课程和项目文件：sidefx.com/tutorials/intro-to-pdg/
要使用 TOP 缓存几何图形，您可以使用 ROP 几何图形输出将节点的结果保存到磁盘。您可以利用工作项属性来确保将每个楔形保存到唯一路径。

Intro to PDG _ 10 _ Rendering in TOPs

Lesson and Project Files: sidefx.com/tutorials/intro-to-pdg/
Learn how to use Rop Fetch TOPs to execute ROPs. Use OpenGL ROPs to achieve fast renders to visualize the city wedges. Similar to the ROP Geometry Output, you need to ensure unique paths for each of the wedges.

课程和项目文件：sidefx.com/tutorials/intro-to-pdg/
了解如何使用 Rop Fetch TOP 来执行 ROP。使用 OpenGL ROP 实现快速渲染以可视化城市楔形。与 ROP 几何输出类似，您需要确保每个楔形的路径都是唯一的。

Intro to PDG _ 11 _ File Copy

Lesson and Project Files: sidefx.com/tutorials/intro-to-pdg/
Since you have two separate camera angles, you can edit the frame values for one of those sequences to create 1 continuous sequence. You can use File Copy to rename and rearrange files procedurally after rendering them.
谷歌翻译：
课程和项目文件：sidefx.com/tutorials/intro-to-pdg/
由于您有两个独立的摄像机角度，您可以编辑其中一个序列的帧值以创建 1 个连续序列。您可以使用文件复制在渲染文件后按程序重命名和重新排列文件。

Intro to PDG _ 12 _ Attribute Create

Lesson and Project Files: sidefx.com/tutorials/intro-to-pdg/
When you rearrange files, some attributes can be out of date. Learn how to use Attribute Create to update attributes. When working with large amounts of work items, it is important to stay organized and consistent in this way.

Intro to PDG _ 14 _ Mosaic

Lesson and Project Files: sidefx.com/tutorials/intro-to-pdg/
To create a mosaic, we need all images of the same frame to be rendered together on one image. We can use partition nodes to create dependencies between work items. This way, one image can be rendered as soon as all the images of that frame are ready and available.
谷歌翻译：
课程和项目文件：sidefx.com/tutorials/intro-to-pdg/
