Question about joints order

ahsan3803 commented 3 years ago

@mks0601 what is the order of joints if we talk about only right hand? Can you confirm that order of joint is same as below?

In above list where 00 is the joints closest to wrist and 03 is the finger tips

If order is not same as above list then what is the order of joints?

mks0601 commented 3 years ago

Yes. Both left and right hands have the same joint order.

@mks0601 I checked InterHand skeleton and seems that joints order is not same as below list

Could you double check about right order?

Oh where did you get this order? The joint order is defined in annotations/skeleton.txt.

@mks0601 I was trying to plot 3D hands using above order. Thanks for clarification.
