[Virtools] CKIkJoint fails

Hello everybody,

I used the CKIkJoint structure but it behaved strange. This is my code:

	CKIkJoint upperArmConstraint;
	CKIkJoint foreArmConstraint;

	upperArm->SetFlags(upperArm->GetFlags()|CK_3DENTITY_IKJOINTVALID);

	upperArm->GetRotationJoint( &upperArmConstraint );
	upperArmConstraint.m_Flags = CK_IKJOINT_ACTIVE_Z|CK_IKJOINT_LIMIT_Y;
	upperArmConstraint.m_Min.x = (float)0;
	upperArmConstraint.m_Min.y = (float)0;
	upperArmConstraint.m_Min.z = (float)-10*PI/180.0;
	upperArmConstraint.m_Max.x = (float)0;
	upperArmConstraint.m_Max.y = (float)0;
	upperArmConstraint.m_Max.z = (float)10*PI/180.0;
	upperArm->SetRotationJoint( &upperArmConstraint );

	...
	while( ... )
		...
		upperArm->FitToJoint;
		...

The funny thing in that piece of code is that I want to restrain the angle
span of the rotation around the z axis but I have to set the flag
CK_IKJOINT_LIMIT_Y.

When I added another degree of freedom - for example the x axis - the angle
restriction completely failed.
What did I do wrong ? The virtools sdk-documentation lacks of a detailed
description for CKIkJoint and CKIkBodyPart.

Can anybody help me ? I am completly despaired because I NEED that
functionality.

Thanks a lot and regards,
	Rudi Lauster
