Ok, thanks, I understand you.
Also, I have to check my source code about the incorrect appearance of 3d objects.
Also i have another question.The rotated modelview matrix passed from Qualco engine to JPCT-AE is actually the modelview matrix of the marker.
When I insert a 3d object, this has a different modelview matrix?
When i rotate a 3d object calling the Object3D.rotateX() method (or rotateY(),rotateZ()) I noticed that when i move the marker or the camera, the rotated object3D is not actually in the same position, it moves slightly.
The same issue i have when i scale the object3d.
How can i solve this issue? I have to use a difference approach to rotate or scale the object3d?
Thanks in advance
