Hi !

I'm having trouble loading joint data information from 'animation' node of collada file.

First, I try to load joints from 'library_visual_scenes' :
The first 2 joints look like that :

<visual_scene id="" name="">
<node name="joint1" id="joint1" sid="joint1" type="JOINT">
<translate sid="translate">0.000000 -2.000000 0.000000</translate>
<rotate sid="jointOrientZ">0 0 1 90.000000</rotate>
<rotate sid="rotateZ">0 0 1 0.000000</rotate>
<rotate sid="rotateY">0 1 0 0.000000</rotate>
<rotate sid="rotateX">1 0 0 0.000000</rotate>
<scale sid="scale">1.000000 1.000000 1.000000</scale>
<extra>
<node name="joint2" id="joint2" sid="joint2" type="JOINT">
<translate sid="translate">2.000000 0.000000 0.000000</translate>
<rotate sid="rotateZ">0 0 1 0.000000</rotate>
<rotate sid="rotateY">0 1 0 0.000000</rotate>
<rotate sid="rotateX">1 0 0 0.000000</rotate>
<scale sid="scale">1.000000 1.000000 1.000000</scale>
<extra>


which went well !

Then, I try to load joints from 'animation' node. Here is the problem, I can't find any jointOrient.

<animation id="joint1-anim" name="joint1">
<animation>
<source id="joint1-translate.Y-output">
<float_array id="joint1-translate.Y-output-array" count="2">-2.000000 -2.000000</float_array>
<animation>
<source id="joint1-rotateZ.ANGLE-output">
<float_array id="joint1-rotateZ.ANGLE-output-array" count="2">0.000000 0.000000</float_array>

<animation id="joint2-anim" name="joint2">
<animation>
<source id="joint2-translate.X-output">
<float_array id="joint2-translate.X-output-array" count="2">2.000000 2.000000</float_array>


So after loading joints, they look like that :
