In this mode, the curves that define the rotation for a given node are represented in Euler-angles, interpolation is performed on each curve independently in Euler space, and keyframes may occur at your discretion-they are not synchronized with the other sibling rotation curves at the node. You can also animate a single rotation ordinate. This is the default setting. Creates curves that have keyframes on sibling curves locked together as in Synchronized Quaternion Curves but the interpolation between keyframes in performed in Euler-space. It's useful to keep rotation keyframes synchronized because rotation is a composition of the three separate rotate values. Deleting just one key on a curve can have a dramatic and unexpected effect on the interpolation. Calculates the rotation interpolation using three orientations about the X, Y, and Z axes, and an angle of rotation. The interpolation between keyframes is defined using quaternion interpolation. Keyframes on related curves are locked together. When you add, delete, or move a keyframe on one curve, the corresponding key is also updated in the sibling curves. For example, if you drag a keyframe on the X curve to frame 14, the corresponding keys on the Y and Z curves also move to frame 14. The Graph Editor displays a quaternion key as a solid diamond shape. Tangents Tangents determine the status of curve segments when they enter and exit from a key. Weighted tangents Weighted tangents represent the amount of influence a tangent has on an animation curve segment. When on, all new tangents are automatically weighted. Weighted Tangents is off by default. See "Edit tangents" in the Keyframe chapter of the Animation guide. Basics 425
