Preprocessing: Missing Code

[kostasfnrs]

Can you please upload the coding part which is responsible for the affordance_data creation, as described here

"Affordance Data. Our affordance data includes 8-dimensional human contact
labels and object contact points. We employ chamfer distance to measure the
distance between all human body joints and object surface points. Following a
predefined distance threshold γ = 0.12, we identify the 8 contact points on the
object surface corresponding to the 8 primary human body joints. Subsequently,
we derive the human contact labels by encoding the indexes of contact joints
into an 8-dimensional vector represented by binary values."

I cannot understand how you create these data and also for which frame you create these data.
