本插件是AE脚本 导入运动数据动作捕捉数据工具 BVH Importer v1.0带教程，大小：35.7 MB，支持AE软件，支持Win/Mac系统，语言：英语。

BVH文件包含角色的骨骼和肢体关节旋转数据。BVH 是一种通用的人体特征动画文件格式,，广泛地被当今流行的各种动画制作软件支持。通常可从记录人类行为运动的运动捕获硬件获得。BVH Importer就是After Effects导入运动数据动作捕捉数据脚本，不仅支持“标准”ZXY Euler旋转，但超越了这一点，接受混合联合旋转。任何XYZ，XZY，YXZ等组合是可以接受的。

What is BVH Importer

A BVH file is a format that was developed by Biovision, a motion capture services company, as a way to provide motion capture data and skeleton hierarchy information in addition to the motion data. A .bvh file is nothing more than a text file that has data that was captured from a moving skeletal system. Another name for this type of data capture is “Motion Capture” which has been abbreviated as mocap. You can find tons of free BVH motion data on the web or motion libraries for sale in BVH format. By using BVH Importer you can convert all these available resources to something that After Effects can handle and enrich your motion content.

The goal of this script is to use motion capture data on an avatar, or an articulated figure, which could be the first step in creating real world motion gestures in After Effects.

Euler angles

BVH Importer not only supports “standard” ZXY Euler rotations, but goes beyond that and accepts mixed joint rotations. Any XYZ, XZY, YXZ, etc combination is acceptable. The tool has a built-in file compatibility check option that will report any errors regarding the BVH file.

Skeleton

You can have skeletons in it’s rest position which will make rigging much easier, even if neutral pose is not defined in the BVH file. No motion data deformations are applied to it at the beginning of the animation. Use options to set the skeleton in the center of composition screen instead of arbitrary offsets defined in the BVH file.

工程流程：

01.Run BVH Importer and import BVH file. Check for file compatibility if it’s your first run for that particular script;

02.Adjust files parameters such as FPS, duration, animation range. Enable rest pose if you are planning on rigging this skeleton;

03.Set composition parameters and geometry options;

04.Apply the Beam Effect in order to get visual lines between joints
