Here's an example of an ASCII FBX that I tried loading in

Thanks for the info.

Yet in the documentation it says animation keyframes should come in? Maybe it is unhappy that I am not supplying it with an attached geometry.

Thanks! I think Swap Top worked pretty well. Only thing I had to manually do was then delete the old key frames for the opposing side and then change the interpolation type to linear, to preserve what I had before, since default is spline.

The code is simple enough to where it can continue to help me understand Python and the Poser methods.

Thanks! Now I get to learn Python.

Oh, is the try except statement so that when you run it from Poser, then it will successfully execute the try statement?

I see. If there is no way to connect poser directly to an external editor, then what is the point of the try: import poser statement?

Otherwise, I do see the value of the fake poser library, as using PyCharm is a lot easier than writing Python scripts in a text editor. I guess I should save my .py files from PyCharm in the Python scripts directory for Poser, and call my script directly from Poser.

Thanks. I'm making incremental progress. The thing I am still confused about is how the actual program becomes involved. If I click on the forearm in the Poser window, how do I get PyCharm to return that Actor with CurrentActor()? Another example, I have Poser open now with 30 key frames:

Yet, when I run my .py file which imports your fake Poser library, the number of frames is returned as 1:

My main goal is to calculate joint positions of the Poser skeleton in time, and then animate the skeleton using matplotlib.

Thank you. It seems that I am failing to even "import poser." I have no issues with this when running PoserPython from Poser. Do I have to set some paths in PyCharm to get it to find poser?

Sets poser = None for me.

Then,

fails me:

Thanks for your patience.

Thank you, very interesting. My first thought was also WorldDisplacement(), but the Python manual is not sufficient enough for me to know exactly what WorldDisplacement() tracks:

For example, if I try to track the "head," then is this the joint center of the neck joint, or is it some centroid for the head mesh? I don't want the centroids, I need the joint centers.

I see, thanks.

Ah, yes, I see that the Body xTran, yTran, zTran suddenly change when I move to the problematic frame. I don't know how, because I always put the actor into the space by translating and rotating the hip; maybe I used the "Body" coordinates by accident once. Thank you, I am happy to have been guided to this clue. Now I just need to back out what all the coordinate systems are in Poser. I wish there was a way to display all the coordinate systems for visualization.

Thanks for your reply. Here is a sampling of the frames:

I've had such a tough time with the coordinates in Poser compared to other programs. How do I find the body transform? My impression was that the body is placed into the space via the hip, because when I rotate the hip the whole body rotates rigidly. Then, every other body part is defined relative to it. Are there any good sources for the coordinates that are used? I find the Poser manual to be cryptic in this regard.

Hi,

I am still trying to understand the difference between WorldDisplacement() and xTran, yTran, zTran for the hip. I have an animation with 59 frames. WorldDisplacement() matches xTran, yTran, zTran for the first 20 frames. Here is the 20th frame:

Note that the 20th frame from Poser should be compared to the 19th frame in the text box. You can see that the xTran, yTran, zTran values match with the WorldDisplacement() print out. This is the case for the first 20 frames.

Now, if I go to the 21st frame, they begin to disagree:

Please compare the Poser dials with the 20th frame in the text box.

I am having a really difficult time wrapping my head around why there is such a disagreement. Is there a way to visualize the global origin and global X Y Z in Poser?

Thanks. After a lot of research, I was able to create the following code:

import poser

actor = scene.Actor("Hip")
for frame in range(scene.NumFrames()):
    scene.SetFrame(frame)
    print actor.WorldDisplacement()

I wanted to validate this process with what I had done before. That is, copy from the Animation Palette and paste into Excel. The first couple of frames match with what I had before. However, later keyframes do not match. I multiply the values by 8.6 to get from PNU to feet, but there is a discrepancy between this value and the dials in the Poser GUI.

Do the xTran yTran zTran dials for the Hip in the Poser GUI correspond to the WorldDisplacement for the Hip actor? Apparently not.

I’m using Rhino, but I guess my question is a little more fundamental. Is there a way that I can visualize the origin in Poser with the world coordinate system emanating out from that?

I made some progress today. I noticed that when you go to key camera positions, I can have direct control of the numbers there. But, I still don’t know where the default origin is.

Thank you.
