....matrix representing the current object s rotation added to the new rotation, and the newrot vector describing the new rotation in terms of its component rotations around the X, Y and Z axes. A further description of the virtual trackball (including implementation specifics) is given by Chen [CMS88] Modifying the Center of Rotation The center of rotation (COR) of an object is the point around which it may be rotated. Each object stores its COR in the COR field of its Transform structure (as described earlier) 46 The localCOR flag of the Transform structure indicates whether the ....

....as applied to pulls of a single vertex. around some axis is described; the direction of the cursor movement determines the rotation axis, and the initial position of the mouse and the length of the movement vector determine the angle of rotation. Implementation specifics are given by Chen [CMS88] Modifying the Center of Rotation The center of rotation (COR) of an object is the point around which it may be rotated. A local COR follows an object as it is moved about; a global COR is unaffected by the transformations applied to an object. SAM IAM increases the power of trackball based ....
