Hello,

I am using the BVH export function.
The BVH default format is as follows.
--
HIERARCHY
ROOT Hips
{
OFFSET 0.000000 0.000000 0.000000
CHANNELS 6 Xposition Yposition Zposition Zrotation Xrotation Yrotation
JOINT Spine
{
OFFSET -0.000000 74.496445 0.000000
CHANNELS 3 Zrotation Xrotation Yrotation
JOINT Spine1
{

I want to change the rotation order to use BVH on another system.
ZXY ->ZYX

Hello Ryu,

Thank you for reaching out to the community regarding your question.
It is not possible to change the rotation order when exporting a BVH. If your other system accepts CSV files, I think this is the only file type that supports converting the rotation order. Otherwise you may also consider exporting to C3D and using the marker data.

If you would like to submit a feature request, please feel free to reach out to us at help.naturalpoint.com.

Best,
Steven
