BioVision Motion Capture (BVH)¶

Reference

Category:: Import-Export
Menu:: File ‣ Import/Export ‣ Motion Capture (.bvh)

Imports or exports bvh-files or files with BioVision Hierarchical data or data of a skeleton (rig) including its animation. Useful for importing data from motion capture devices.

Enabling Add-on¶

This add-on is enabled by default, in case it is not:

Open Blender and go to 애드온(add-on) section of the Preferences.
Search “BioVision Motion Capture (BVH) format” and check the Enable Extension checkbox.

특성¶

Import¶

Target

The motion capture data type.

Armature:: The bvh-file contains an animated rigged skeleton such as a walking motion capture.
오브젝트:: The bvh-file contains a static (not animated) mesh object such as a character model.

변형¶

축척(Scale)

Factor to increase the physical size of the BVH.

Rotation

Rotation order of the BVH.

Forward / Up

Since many applications use a different axis for pointing upwards, these are axis conversion for these settings, Forward and up axes – By mapping these to different axes you can convert rotations between applications default up and forward axes.

Blender uses Y forward, Z up (since the front view looks along the +Y direction). For example, its common for applications to use Y as the up axis, in that case -Z forward, Y up is needed.

애니메이션¶

Start Frame: The start frame, in Blender, to start playback of the BVH animation.
Scale FPS: Scales the frame rate from the BVH file to the scene frame rate set in Blender, otherwise each BVH frame maps directly to a frame in Blender.
Loop: Cycles the animation playback.
Update Scene FPS: Set the scene’s frame rate to match the frame rate of the BVH file.
Update Scene Duration: Extend the scene’s duration to match the BVH’s duration.

Export¶

변형¶

축척(Scale): Factor to increase the physical size of the BVH.
Rotation: Rotation order of the BVH.
Root Translation Only: Only write the translation animation channels for the root bone.

애니메이션¶

Start / End: Sets the range of animation to export to the BVH file.
