Description

动画的控制方法、装置、存储介质和电子装置
本申请要求于2018年12月05日提交中国专利局、申请号为201811481911.5、申请名称为“动画的控制方法、装置、存储介质和电子装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及动画领域，具体而言，涉及动画的控制。
背景技术
游戏里的动画大部分是美术在数字内容创建(Digital Content Creation，DCC)软件(例如软件Maya、3dsMax等)中制作，然后导入游戏引擎中用状态机在不同的动画切换。这种制作方式的优点是美术人员可以利用软件的制作优势，做出逼真的动画。对于眼球始终朝向摄像机这个场景来说，需要美术在关键的朝向制作动画，运行的时候根据这些关键朝向做动画插值。
为了解决实时交互的问题，动画也要根据用户的输入做出及时的反馈，因此，基于子骨骼节点带动父骨骼节点运动的反向动力学(Inverse Kinematics，IK)动画也广泛应用在游戏引擎里。IK动画是通过末端骨骼的位置来反向推导其他骨骼的运动。比如伸手去拿一个茶杯，茶杯的位置是目标，IK动画解算从手指到手臂的动画。IK动画的优点是实时计算动画，不需要美术的参与。对于眼球始终朝向摄像机这个场景来说，只要指定眼球的朝向，IK系统就会自动算出眼球，头部以及脖子的朝向。

可选地，在将本申请的技术方案应用于联网应用(如联网游戏)的情况下，上述硬件环境中还可包括为终端101提供业务服务(如游戏服务)的服务器102，由服务器102执行本申请的动画的控制方法，并将执行结果作为服务(如 游戏服务)的一部分提供给终端101，来调整终端上待调整目标的朝向，终端101可通过网络与服务器102进行连接，上述网络包括但不限于：广域网、城域网或局域网，终端101可以是手机终端，也可以是PC终端、笔记本终端或平板电脑终端。
本申请的技术方案所适用的场景包括但不局限于如下场景：

本申请的技术方案还可以应用在游戏场景中，如多人在线战术竞技(Multiplayer Online Battle Arena，MOBA)游戏、第一人称射击类(First-person shooter，FPS)游戏、第三人称射击类(Third-person shooter，TPS)游戏等，可以将上述游戏的游戏应用安装在上述终端101上，以形成游戏的客户端，玩家通过客户端在游戏场景中参与游戏，游戏场景中包括待调整目标所属的目标对象，该目标对象可以为当前用户在游戏场景中操控的游戏角色、该游戏角色的队友、该游戏角色的敌人等对象，而且待调整目标可以是人物角色的某个器官或者身体结构的某个部分，如眼睛等。当玩家在游戏场景中参与游戏的过程中，若该游戏为单机游戏、多人本地互联的游戏，可由其中一个终端执行本申请的技术方案来调整目标对象上待调整目标的朝向，还可将执行结果同步给其它终端，若该游戏为联网游戏，可由服务器102执行本申请的技术方案来调整目标对象上待调整目标的朝向，并将执行结果同步给参与游戏的终端。
下面以本申请实施例的动画的控制方法由终端101来执行为例进行说明， 终端101执行本申请实施例的动画的控制方法也可以是由安装在其上的客户端(如游戏应用的客户端)来执行，例如，将本申请的动画的控制方法嵌入到游戏应用的游戏引擎中，作为游戏引擎自身逻辑的一部分；或者将本申请的动画的控制方法嵌入到游戏应用的游戏逻辑中，作为游戏逻辑的一部分。图2是根据本申请实施例的一种可选的动画的控制方法的流程图。如图2所示，该动画的控制方法包括：
S202，终端获取动画中虚拟摄像机的第一位置和动画中待调整目标的第二位置。
在动画中可以表现多个对象，待调整目标可以是对象的一部分。其中，对象可以是人物角色，待调整目标可以是人物角色的某个器官或者身体结构的某个部分，如眼睛等。该动画可以为游戏动画，待调整目标可以是游戏角色中的眼睛。第一位置是虚拟摄像机在动画中的位置，第二位置是待调整目标在动画中的位置，游戏场景和游戏场景中各个角色可由游戏引擎渲染出，在获取第一位置和第二位置时，可以在游戏引擎中获取其所渲染的待调整目标在动画中的第二位置，并利用游戏引擎的配置文件(配置文件中配置有各个虚拟摄像机的状态、移动逻辑等)获取虚拟摄像机的第一位置。第一位置和第二位置都可以采用三维坐标表示，三维坐标可以利用矩阵表示。
S204，终端根据第一位置、第二位置和待调整目标所属目标对象的坐标信息确定待调整目标的旋转角度。
获取第二位置到第一位置的矢量(该矢量可以为三维坐标系中的矢量)，如图3所示，利用该矢量乘以矩阵[0 0 1]，得到待调整目标的x轴坐标；利用该矢量乘以矩阵[0 1 0]，得到待调整目标的y轴坐标；利用该矢量乘以矩阵[1 0 0]，得到待调整目标的z轴坐标。从而得到待调整目标在三维空间中坐标的矩阵表达，该矩阵为旋转矩阵M r(即第一矩阵)，为了抵消游戏过程中玩家控制角色的旋转以及初始状态下角色没有对齐X轴，获取玩家控制角色旋转时角色的旋转矩阵M t(即第二矩阵)和初始状态下角色的旋转矩阵M i(即第三矩阵)，将以上旋转矩阵M r、旋转矩阵M t和旋转矩阵M i级联起来，得到待调整目标的目标矩阵M：
Figure PCTCN2019114251-appb-000001
其中，待调整目标所属目标对象为游戏角色，目标对象的坐标信息包括旋转矩阵M t和旋转矩阵M i，旋转矩阵M t和旋转矩阵M i可以通过游戏引擎获得。
可选地，上述M i、
Figure PCTCN2019114251-appb-000002
M r均可以为三行三列的矩阵，旋转矩阵M t表示游戏角色在玩家的控制下游戏角色自身与玩家的控制操作对应的旋转矩阵(即从控制前的状态转换为控制后的状态之间的转换矩阵)和初始状态下角色的旋转矩阵M i可以通过游戏引擎提供的应用程序接口API获取：
Figure PCTCN2019114251-appb-000003
其中，i 11至i 33为常数；
Figure PCTCN2019114251-appb-000004
其中，t 11至t 33为常数；
Figure PCTCN2019114251-appb-000005
其中，r 11至r 33为常数为按照第二位置到第一位置的矢量计算出来的数值。
Figure PCTCN2019114251-appb-000006
R 11至R 33的数值可以直接利用M i、
Figure PCTCN2019114251-appb-000007
M r中各个元素的数值计算出来。
即，根据第一位置、第二位置和待调整目标所属目标对象的坐标信息确定待调整目标的旋转角度包括：根据所述第二位置到所述第一位置的矢量，获取所述待调整目标的第一矩阵；获取目标对象的旋转矩阵，作为第二矩阵，其中，第二矩阵为目标对象在预定场景中被控制旋转时的矩阵；获取目标对象在初始状态下的旋转矩阵，作为第三矩阵；对第一矩阵、第二矩阵和第三矩阵进行级联，得到目标矩阵；将目标矩阵转换成旋转角度。
其中，第一矩阵为旋转矩阵M r，第二矩阵为旋转矩阵M t，第三矩阵为旋转矩阵M i。在得到目标矩阵之后，由于目标矩阵无法直观的表示旋转角度为 多少，为了便于调整待调整目标的旋转角度，可以利用以下公式将目标矩阵转换成旋转角度。
ω x＝atan2(R 32，R 33)；
Figure PCTCN2019114251-appb-000008
ω z＝atan2(R 21，R 11)。
旋转角度可以包括相对于X轴的角度ω x、相对于Y轴的角度ω y以及相对于Z轴的角度ω z。
S206，终端利用旋转系数对旋转角度进行调整，得到目标角度。
待调整目标按照目标角度旋转后，待调整目标将朝向虚拟摄像机，由于该目标角度表示的就是调整前的角度与朝向虚拟摄像机时的角度之间的角度差值，所以按照目标角度调整后的待调整目标是朝向虚拟摄像机的，旋转系数用于调整待调整目标与关联目标的旋转角度的比例，关联目标是与待调整目标具有联动关系的目标，一种可选的方式中，旋转系数是由动画美术预先设定的。
对于一个角色来说，旋转角色的某个部分可能会导致其他部分的联动，或者，旋转某个部分时同时旋转其他相关的部分才会使得旋转效果比较自然，因此，在旋转待调整目标时，也要考虑其他关联目标的旋转角度，也就是说，为待调整目标和关联目标设置旋转角度的比例(即前述的旋转系数)。
举例来说，待调整目标为角色的眼睛，关联目标包括角色的头部和脖子，眼睛、头部和脖子的旋转比例为3:2:1，则，代入M i、
Figure PCTCN2019114251-appb-000009
M r中各个元素的数值计算出来M，然后，在确定了眼睛的目标角度为与X轴之间的角度减少30°的情况下，头部旋转(即与X轴之间的角度减少)20°，脖子旋转(即与X轴之间的角度减少)10°。在这个例子中，待旋转目标的旋转系数可以为3，其与头部之间的比例为3:2，其与脖子之间的旋转比例为3：1。此处的旋转系数可以根据待调整目标在对象中的不同位置进行设置，使得待调整目标按照目标角度旋转后，朝向虚拟摄像机，且对象的动作表现比较自然，如图4所示，眼睛旋转了30°，头部旋转了20°，脖子旋转了10°。
需要说明的是，相对于Y轴和Z轴的旋转角度与相对于X轴的旋转方式类似。
S208，终端控制待调整目标按照目标角度进行旋转，使得旋转后的待调整目标朝向虚拟摄像机。
本实施例通过待调整目标和虚拟摄像机的位置确定待调整目标的坐标的矩阵表达，根据待调整目标的坐标之后确定待调整目标的旋转角度，可以根据输入的旋转系数对旋转角度进行调整，得到目标角度，然后控制待调整目标按照目标角度进行调整，从而使得待调整目标的旋转更加灵活，表现出的效果更加自然，解决了现有技术调整旋转角度时不灵活的技术问题。
可选地，控制待调整目标按照目标角度进行旋转包括：获取待调整目标的当前旋转矩阵(当前旋转矩阵与旋转矩阵M t、旋转矩阵M i类似，可以通过游戏引擎提供的应用程序接口API获得)，对于游戏角色而言，其旋转包括两个部分，其一是受控于玩家等的整个游戏角色的旋转，当前旋转矩阵即用来表示当前时刻整个角色的旋转，其二是为了使得待调整目标始终面向虚拟相机而作的旋转，用目标矩阵或者目标矩阵转换来的目标角度表示，这二者的叠加即相当于最终的旋转；将目标角度应用在当前旋转矩阵上，得到目标矩阵，其中，目标矩阵表示的旋转角度为待调整目标朝向虚拟摄像机的角度。此时，控制所述待调整目标旋转至目标矩阵，能够使得待调整目标始终面向虚拟相机。
作为一个可选的示例，当前旋转矩阵表示旋转前待调整目标的空间位置，可以用M e表示：
Figure PCTCN2019114251-appb-000010
其中，e 11至e 33为常数。
M a＝[ω x，ω y，ω z]。
对当前旋转矩阵和表示目标角度的矩阵M a相乘，以便基于M e和M a的乘积矩阵完成待调整目标的旋转。在需要眼睛朝向虚拟摄像机时，完成旋转后的待调整目标朝向虚拟摄像机，此处的需要可以是指游戏中某个时刻需要将待调整目标朝向虚拟摄像机，也可以是整个游戏过程中保持待调整目标朝向虚拟摄像机，如果中间一旦出现待调整目标未朝向虚拟摄像机的情况则按照本申请的上述方法进行调整，调整后的效果如图4所示。
可选地，本申请实施例提供的动画的控制方法还包括：设置待调整目标进 行旋转所需的时间，作为旋转时间；根据旋转时间对旋转角度进行线性差值，得到差值后的旋转角度，以便利用旋转系数对所述差值后的旋转角度进行调整，得到目标角度，其中，差值后的旋转角度与旋转系数相乘得到目标角度。
需要说明的是，本申请实施例不限定“旋转时间”的获取时间，只需在执行“根据旋转时间对旋转角度进行线性差值”之前完成即可。
为了使得旋转的效果自然不生硬，避免待调整目标瞬间旋转目标角度，在输入旋转系数对旋转角度进行调整之前，对旋转角度根据时间做一次线性插值，即，设置旋转所需的时间，差值后的旋转角度和旋转系数相乘可以调整旋转所需的时间。例如，在旋转角度为30°的情况下，如果旋转时间为1秒，则控制待调整目标在1秒钟旋转30°；如果旋转时间为5秒，则控制待调整目标在5秒钟内旋转30°。线性差值不改变待调整目标所要旋转的角度，仅改变旋转所需要的时间。将旋转时间设置为5秒，可以表现出待调整目标慢慢旋转的效果。
可选地，控制待调整目标按照目标角度进行旋转包括：获取至少一个关联目标的旋转系数，作为至少一个旋转系数；将至少一个旋转系数应用在至少一个关联目标中对应的关联目标上，得到至少一个旋转角度；控制至少一个关联目标和待调整目标按照目标角度和至少一个旋转角度逐级进行旋转。
在确定了关联目标的旋转系数之后，就确定了关联目标的旋转角度。举例来说，待调整目标为角色的眼睛，关联目标包括角色的头部和脖子，眼睛、头部和脖子的旋转比例为3:2:1，则，在确定了眼睛的目标角度为30°的情况下，头部旋转20°，脖子旋转10°。确定每个部分的旋转角度之后，按照骨骼的层级逐级进行旋转，也就是按照从脖子到头部再到眼睛的顺序进行旋转。
如图5所示，骨骼A表示脖子，骨骼B表示头部，骨骼C表示眼睛，骨骼的层级顺序为骨骼A到骨骼B到骨骼C，先计算骨骼A的旋转角度，然后根据美术的输入调整旋转，即根据输入旋转系数调整骨骼A的旋转角度，叠加到已有的旋转，即叠加到骨骼A的当前旋转角度上，完成骨骼A的旋转。计算骨骼B的旋转角度，然后根据美术的输入调整旋转，即根据输入旋转系数调整骨骼B的旋转角度，叠加到已有的旋转，即叠加到骨骼B的当前旋转 角度上，完成骨骼B的旋转。计算骨骼C的旋转角度，然后根据美术的输入调整旋转，即根据输入旋转系数调整骨骼C的旋转角度，叠加到已有的旋转，即叠加到骨骼C的当前旋转角度上，完成骨骼C的旋转。
图5虽然示出了分别计算骨骼A、骨骼B和骨骼C的旋转，但是，本实施例可以在计算出骨骼C的旋转角度后，根据旋转系数直接得到骨骼A和骨骼B的旋转角度，进而完成从骨骼A到骨骼C的逐级旋转，最终旋转的结果可以参见图4，图4中人物眼睛(相当于骨骼C)与X轴之间的角度减少30°，头部和脖子(相当于骨骼A和骨骼B)与X轴之间的角度分别减少20°和10°。
本实施例可以实时的产生眼球跟踪摄像机的效果，动画平滑自然，看不出人工痕迹，也不影响身体其它部分的动画，比如朝你看的同时也能眨眼。如前述内容描述，本申请的技术方案相当于提供了一种将虚拟场景中的目标对象的某个部位(即待调整目标)调整为朝向虚拟摄像机的方案，该虚拟场景可以为前述的游戏场景、社交场景等。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本申请所必须的。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请各个实施例所述的方法。
