Thanks for sharing this dataset!

I'm wondering what's the .bin and .txt files in the tracked mesh folder? Like ./m--20171024--0000--002757580--GHS/tracked_mesh/E002_Swallow/[000431.bin, 000431_transform.txt]

Hi,

transform.txt is a 3x4 matrix consiting of rotation and translation that represents the rigid body transformation of the head mesh at each frame. and .binfile contains the per frame vertex. You may refer to data structure and data asset to get more description, thanks!
