Hello All ,
I have a question about the egg file format.
In Bundle, you create tables that can include a transform information for the joint at each frame.
Question 1: Net Transform or Parent relative Transform?
This transform information is the Net Transform of the joint or the relative Transform versus the parent Node?
Question 2: Transform in Parent Local Space or World Space?
This transform information must be provided in Parent Local space or World Space ?
Yep i know, the bad news is i’m forced to create egg file myself without using a python runtime (so without EGGDATA 
(((()
Lol i’ve found back the post where i asked exactly the same questions for 3 years ago for another assigment ((
So the answers are :
a)the transformation matrix to be specified for a joint in tables of an egg file is relative to the parent node only
b)Joints are defined using a local transform, vertices are defined in an egg file using global coordinates
Other pieces of information are:
c)the net transform of each node is derived by pre multiplying the parent’s net transform with the node’s local transform.
That is, Mn = Mn-1Mn-2…M0, where M0 is the root transform.
d)transform matrices in Panda are represented row-major
(which does reverse the meaning of premultiply and postmultiply from a column-major representation)
e)The tables hierarchy should exactly match the skeleton hierarchy.
