I was referring to an API documentation on Quarternion related stuff. I want to use the last constructor which is written "Constructor from Euler angles". The constructor itself is as below:

btQuaternion::btQuaternion ( const btScalar & yaw,
                             const btScalar & pitch,
                             const btScalar & roll   
                           )

My question is regarding the angles. Should the angles in the input argument be in degree or radian?

Always radians, degree are never used.

Radians. They are the standard, see REP 103
