Sorry about lack of clarity. Both applications are closed sourced and there is no information about how they store the data.
The transfer file format converts x,y,z angles to Axis-angle representation
I have two 3d applications and when an object(a cube for example) is transferred between them, the rotation values of the cube change(the object stay at the same location. translation and scale values stay the same) and I can't find why that occurs and it's driving me crazy.
app 1 rotation...
