Fix common issues such as stereo keystone alignment and left/right-eye colour and focus mismatches
Render left and right-eye images from a single clip using Z-Depth data

PFDepth的所有功能嵌入PFTrack所有PFDepth节点现在都完全集成在PFTrack中更多的方法来创建和操纵深度图：
更新了Z-Depth Solver节点

User Interface Updates and Productivity Enhancements

Node creation panel has been updated with nodes organised into groups to make them easier to find
New Custom node group, where commonly used nodes can be placed for quick access
Tree layouts can be saved as XML preset files to help quickly construct common sets of nodes
Tree preset XML files can be copied onto other machines or given to users to share common layouts

用户界面更新和生产力增强节点创建面板已经被组织成组的节点进行了更新

使其更容易找到
新建自定义节点组，其中可以放置常用节点以进行快速访问
树布局可以保存为XML预设文件，以帮助快速构建常见的节点集
树预设的XML文件可以复制到其他机器上或给予用户共享通用布局

Extended Digital Cinematography Camera Support

Added support for reading ARRI RAW media files
Camera and lens metadata is automatically read from RED and ARRI source files
ARRI metadata can also be read from DPX, OpenEXR or Quicktime ProRes files
Added support for importing custom XML metadata to the Clip Input node
All metadata is passed through the tree and can be accessed by python or export nodes

扩展数字摄影摄像机支持增加了阅读ARRI RAW媒体文件的支持
从RED和ARRI源文件自动读取相机和镜头元数据
也可以从DPX，OpenEXR或Quicktime ProRes文件读取ARRI元数据
增加了将自定义XML元数据导入到Clip Input节点的支持
所有元数据都通过树传递，可以通过python或export节点访问

Advanced Photogrammetry Texture Extraction Tools

An optimized texture map can now be created automatically in the Photo Mesh node as part of the simplification process
Exposure and brightness differences in the source media can be automatically corrected to provide the best quality texture map
Exposure balanced images are automatically passed down-stream, and can be used in the Texture Extraction node for manual texture painting if required
Normal, displacement and occlusion maps can also be generated during simplification, to ensure the simplified mesh retains as much visual fidelity as possible
Normal maps support both world and Mikk tangent spaces
Occlusion maps can be generated for either the sky or local surface occlusion
Additional texture maps are exported automatically by the Export node

高级摄影测量纹理提取工具作为简化过程的一部分

现在可以在Photo Mesh节点中自动创建优化的纹理贴图
源媒体中的曝光和亮度差异可以自动更正，以提供最优质的纹理贴图
曝光平衡图像自动传递到下游，如果需要，可以在纹理提取节点中使用手动纹理绘画
在简化过程中也可以生成正常，位移和遮挡图，以确保简化的网格尽可能保留视觉保真度
正常地图支持世界和Mikk切线空间
遮挡图可以产生天空或局部表面遮挡
其他纹理贴图由导出节点自动导出

Experimental RGBD Pipeline for Depth Sensors

Z-Depth data captured by external sensors can be attached to an RGB clip and passed down the tracking tree
Auto Track and User Track nodes updated to read z-depth values for trackers at each frame
Camera Solver node will use tracker z-depth values to help solve for camera motion
Can reduce drift in long shots
Can improve accuracy when tracking complicated camera movements
