Coordinate Transformation of SMPL
I obtained the rotation matrices of each joint of SMPL from images using mmhuman3d. However, when I directly imported them into Unity to control the motion of the SMPL model using SMPL for Unity, I found that the movement of the SMPL model was incorrect.
I am aware of the coordinate systems for each joint in Unity, but I am unsure about the joint coordinate systems obtained from mmhuman3d. Therefore, I am unable to derive the rotation matrices from the mmhuman3d coordinate system to the Unity coordinate system.
Could you please advise me on how to resolve this issue? Thank you for your assistance.
