Extracting Data From a Motion file

[wildr3d]

We need to tell a client on location right now how to interpret a motion file to get the X,Y,Z and H,P,B data directly from the file. When we view the file in Wordpad we see this:

If anyone can help, I'd really appreciate it.

Channels:
0-2 is XYZ Position
3-5 is HPB
6-9 is XYZ Scale

Numbers in bold are what are numeric displayed in Layout. I would say the first group is the entire flosting point number for the motion.

Key is key frame but I can't see reference to which keyframe - yet.

Example:

NumChannels 9
Channel 0
{ Envelope
3
Key -3.1467399999999999 0 0 0 0 0 0 -2.2123886793798229 0
Key -5.3598661422729492 0.83333333333333337 0 0 0 0 1.2042550514475503 0.60212752572377515 0
Key -1.3403574228286743 1.25 0 0 0 0 4.0168308322227926 0 0
Behaviors 1 1

Going to see if I can figure out how to tell the keyframe.

OK to get the frame that the keyframe is on take the frame rate and multiply by the second group of numbers.


Example:

Key -3.1467399999999999 0 0 0 0 0 0 -2.2123886793798229 0
Key -5.3598661422729492 0.83333333333333337 0 0 0 0 1.2042550514475503 0.60212752572377515 0
Key -1.3403574228286743 1.25 0 0 0 0 4.0168308322227926 0 0

My scene is 24 frames per second so:

First keyframe is at 0.

Second keyframe is 24 X 0.8333333... is `19.999999 or frame 20.

Third keyframe is 24 X 1.25 is 30 - frame 30.

Not sure about the other numbers yet velocity perhaps?

BTW: HPB is not what is displayed, I figure it has got to be some math with 360 or a percentage somehow.

Also might there be a plugin that will read this data and display it in plain terms?

It is, but in radians.

Thanks for the quick replies, the person here who knows how to interpret the data had left for the weekend and we got hold of him.

Again Thanks.
