Description
Technical field
The embodiment of the present invention relates to field of computer technology, relates in particular to a kind of object and turns round operation realizing method and device.
Background technology
In the creation of three-dimensional animation, game or advertisement etc., often relate to creation the turning round of object, such as turning round of role in personage, online game in animation etc.The turning round of object refer to role, animated character etc. from current place towards vectorial current location, while turning round target towards vectorial target location.
In prior art, take online game as example, often adopt single shaft to turn round to realize turning round of role in game.First setting role is the object of turning round operation, and this object can be by the previous dynasty to defining with crown direction and current place plane.The direction of motion of object be the previous dynasty to, object has predefined place plane, for example character, during its standing, the surface level at place, center is current place plane, perpendicular to current place plane be the crown towards, corresponding, object in this plane, have left towards with the right side towards.Each object all has the volume of self, can spherically determine the space that object is occupied.
Single shaft has been turned round no-radius single shaft and has been turned round with non-no-radius single shaft and turn round two kinds.It is to imitate the method for turning round of turning round mode in reality that non-no-radius single shaft is turned round, and that is to say that in the process of turning round the arc length that object determine to radius by current location winding in world coordinate system turns to that target location realization turns round; No-radius single shaft is turned round and is referred to that object crown in world coordinate system, towards constant, rotates in surface level, during towards difference, also in perpendicular, turns round on the crown of current location and target location simultaneously.For no-radius single shaft turn round be by previous dynasty of current location to previous dynasty of vector sum target location to the normal vector of the common place of vector face, be T axle, the crown that is to say current location towards or the crown, target location towards axle, allow role around previous dynasty of this T axle rotation current location and target location between angle, thereby complete single shaft, turn round.Shown in Fig. 1, be that in prior art, no-radius single shaft is turned round schematic diagram.Object is in world coordinate system (X, Y, Z) in the drawings, and the coordinate of (X1, Y1, Z1) is the coordinate of object current location, and the coordinate of (X2, Y2, Z2) is the coordinate of subject object position; Wherein, the previous dynasty that X1 and X2 are current location to the previous dynasty with target location to; Y1 and Y2 be the left side of current location towards the left side with target location towards; Z1 and Z2 be the crown of current location towards the crown with target location towards, and Z1, Z2 and T axle are to be same axle.Under this state, object can, by take T axle as axis, rotate the angle between X1 and X2, thereby turn round target location by current location.
For no-radius single shaft, turn round, if the crown of current location towards the crown of vector sum target location when there is certain angle in vector, at this moment in the process of turning round role's the crown towards just no longer fixing.Because axle when role turns round can not be with the crown of current location towards vector, can not be with the crown of target location towards vector, and then must redefine a new axle and realize and turning round.If suppose that this axle is L, L axle is by calculating to vectorial cross product the previous dynasty to vector sum target location previous dynasty of role's current location, in whole process of turning round, role's the crown is spread certain angle towards meeting around axle L like this, and then the fluency of role's the process of turning round is reduced.Shown in Fig. 2, be that in prior art, single shaft is turned round middle current location and the crown, target location towards not identical equivalent schematic; As shown in Figure 2, when the crown of current location towards the crown of Z1 and target location when Z2 is not identical, now to determine L axle to X2 the previous dynasty to X1 and target location the previous dynasty of current location, object by current location when L axle turns to target location, because of in rotation process, the crown of current location and target location is towards changing, and object can form a taper and waves, and causes the distortion of object and not smooth etc.And, when the single shaft mode with no-radius of turning round realizes, because of L axle, take role current initial point when the vector position and turn round as axle, the process that can make to turn round exists a taper to wave, make game role turn round process not smooth, be unfavorable for promoting user's experience effect.
