Hey,
Sorry to bother you again. First of all, I want to thank you. Your Add-on is very useful for our research project.
However, I have a question/feature request for the add-on. Could you please add a feature to allow users to choose the shape of the marker? Right now, it's just using the default cube. Could you add an option to load marker with the sphere shape? If you don't have time to implement UI, could you tell me how to modify the source code?

The axis_interpretation function reads the screen axis data from the file using reader.get_screen_axis()
which returns axis in string format ('+X', '-Y', etc.) here.
The code afterwards just assumes this data to be numeric vectors instead. Which causes an exception when trying to import files with screen axis parameters.
This could easily be resolved by using a dictionary to retrieve the correct vector like this:
axis_dict = {
'+X': [1,0,0],
'-X': [-1,0,0],
'+Y': [0,1,0],
'-Y': [0,-1,0],
'+Z': [0,0,1],
'-Z': [0,0,-1],
}
I am still unsure if this function works correctly though as I dont know what X_Screen and Y_Screen should actually mean in a 3D context.
The code seems to assume that its the forward and up axis. But shouldnt it be the right and up axis instead?
I could not find a proper definition on those parameters, as the c3d specification is sparse on these parameters:
https://www.c3d.org/HTML/default.htm?turl=Documents%2Fspecification.htm
I succeeded to install this addon. The file/import/c3d got enabled, but not the file/export/c3d :(
Is it normal ? I am using Blender 3.1
Thanks !

Hi,
I installed the add-on successfully, but couldn't import all the frames. My c3d file contains up to 3270 frames but only the first 800 frames are loaded. Here is the file I used to import file. Could you please help me to fix it?
Best,

Hey ive just started using your plugin and have been wondering how to connect an armature/mesh to it. Any easy ways of doing this?
