BioVision Motion Capture (BVH)¶

Reference

Category:: Import-Export
選單:: 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 附加元件 section of the Preferences.
Search "BioVision Motion Capture (BVH) format" and check the Enable Extension checkbox.

屬性¶

Import¶

Target

The motion capture data type.

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

Transform¶

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.

動畫¶

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¶

Transform¶

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.

動畫¶

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