摄影测量已经成为3D行业不可或缺的一部分,尤其是在为电影、电视和游戏创作数字角色时。在这个5.5小时的研讨会中,经验丰富的高级3D艺术家和面部建模师Adam Spring深入介绍了摄影测量学,重点介绍了单摄像头扫描的使用。本课程的主题包括摄影原理、捕捉工具和捕捉头部扫描的拍摄模式;以及用例、例子和所涉及的限制。

亚当采取游击方式,使用单摄像头头部扫描来捕捉3D头部。在Lightroom中对结果图像进行预处理之前,显示了他的完整过程。在这个特定的工作流中,在ZBrush中开始网格清理工作之前,Agisoft Metashape被引入来处理扫描数据。Adam然后分享了他如何使用Wrap在ZBrush中包装他的自定义拓扑,以及如何使用Photoshop和Mari的组合来删除任何不想要的纹理细节。研讨会的最后一部分探讨了如何优化扫描数据,使其可以用于任何实体角色外观开发流程。

Photogrammetry has become an integral part of the 3D industry, particularly when it comes to creating digital characters for film, TV, and games. In this 5.5-hour workshop, Adam Spring, an experienced senior 3D artist and facial modeler, provides an in-depth introduction to photogrammetry, with a focus on using single-camera head scanning. The topics included in this workshop cover the principles of photography, capture kits, and shooting patterns for capturing a head scan; as well as use cases, examples, and the limitations involved.

Adam takes a guerrilla approach to capture 3D heads using single-camera head scanning. His complete process is shown before he pre-processes the resulting images in Lightroom. With this particular workflow, Agisoft Metashape is introduced to process the scan data, before the mesh cleanup work can begin in ZBrush. Adam then shares how he wraps his custom topology in ZBrush using Wrap, as well as how to remove any unwanted texture details using a combination of Photoshop and Mari. The final segment of the workshop explores how to optimize scan data to a point where it can be used for any solid character look development pipeline.
