在一些游戏场景中，当用户控制游戏角色时，会操控游戏角色来呈现出不同的视角。例如控制游戏角色在上、下、左、右、前、后等不同的方向上平移，或者控制游戏角色旋转，从而使得游戏画面呈现出不同的视角。
相关技术中，对于游戏角色的视角的操控，是在游戏画面中设置多个控件，每个控件实现对应的功能，从而控制游戏画面呈现出不同的视角。
但是，这样会导致游戏画面中的控件数量过多，控件对游戏画面造成遮挡，最终影响用户的游戏体验。
为了解决上述技术问题，本申请实施例提供了一种视角切换方法、装置、计算机设备及计算机可读存储介质。该视角切换方法能够通过一个视角控件实现多种模式的视角控制。
需要说明的是，本申请所提供的视角切换方法可以应用于手机、电脑等计算机设备，计算机设备提供图形用户界面，通过图形用户界面可以显示虚拟场景和虚拟场景中的视角控件。其中，虚拟场景可以是游戏场景，视角控件可以是游戏场景中的游戏角色对应的控 件。
请参阅图1，图1是本申请一可选实施例提供的视角切换方法的流程示意图。该视角切换方法可以包括如下步骤：
110、在视角控件处于第一操控模式下，响应于在视角控件的默认区域中的第一移动操作，根据第一移动操作获取虚拟相机在所处竖直平面上的第一移动参数，根据第一移动参数控制虚拟相机在所处竖直平面移动。
在一些实施方式中，视角控件对应有多种操控模式，每一操控模式下的视角控件的图标有所不同。视角控件默认的操控模式为第一操控模式，当视角控件的操控模式为第一操控模式时，则用户操控视角控件时，计算机设备可以捕获视角控件的第一移动参数。
例如，当视角控件的操控模式为第一操控模式时，用户可以通过点击、拖动、滑动等方式来操控视角控件，从而在视角控件的默认区域中进行第一移动操作。其中视角控件的默认区域可以理解为是一个图标区域，比如视角控件的图标是圆形的，则默认区域则为该视角控件的圆形图标区域。
当视角控件的操控模式为第一操控模式时，针对于视角控件操作的触控点在视角控件对应的默认区域内。比如视角控件为圆形图标，该圆形图标的半径为R，那么预设范围可以是该圆形图标的圆心为中心、半径范围为3R的圆形范围。具体可以根据实际视角操作需求而设定。在此仅做例举，不对本申请做出限制。
具体地，用户在操控视角控件的时候，计算机设备可以捕获用户的触控点，然后根据触动点的移动距离、移动方向来确定出第一移动操作。
在一些实施方式中，当视角控件的操控模式为第一操控模式时，视角控件对应的操控逻辑为第一操控模式的第一操控逻辑，即用户操作视角控件时，按照第一操控逻辑来实现控制视角。
在一些实施方式中，当视角控件的操控模式为第一操控模式时，视角控件对应的图标为第一显示图标，第一显示图标有助于用户了解视角控件当前对应的操控模式。
例如，在用户操控视角控件的时候，视角控件有对应的触控点，该触控点可以是用户通过手指触摸触控显示屏所生成的触控点，该触控点还可以是用户通过鼠标等外设在屏幕上生成的触控点。计算机设备可以根据触控点来确定出第一移动操作。
在一些实施方式中，计算机设备可以获取第一移动操作的第一操作移动距离和第一操作移动方向；根据第一操作移动距离和第一操作移动方向，确定虚拟相机在所处竖直平面的第一相机移动方向和第一相机移动距离，其中第一移动参数包括第一相机移动距离和第一相机移动方向。
在一些实施方式中，计算机设备可以根据第一移动距离确定出虚拟相机在虚拟场景中对应比例的第一相机移动距离；将第一移动方向确定为虚拟相机在虚拟场景中的第一相机移动方向；根据第一相机移动距离和第一相机移动方向控制虚拟相机在所处的竖直平面内移动，从而使得虚拟相机拍摄出第一画面。
例如，当第一操控模式下，在三维的虚拟场景中，虚拟相机在竖直平面内移动，比如虚拟相机面对拍摄物体，虚拟相机在竖直平面内进行上下左右移动。比如虚拟相机的移动方向和虚拟相机的拍摄方向垂直。
此时，计算机设备可以建立虚拟相机移动时对应的平面坐标系，然后移动距离和移动方向设置在该平面坐标系中，从而得到移动距离和移动方向对应的向量。然后获取该向量在坐标轴上对应的分向量，然后将分向量的方向垂直于虚拟相机的拍摄方向的分向量确定为目标分向量，然后确定出目标分向量的方向为虚拟相机对应的第一相机移动方向，然后将目标分向量的模乘以对应的比例，则得到虚拟相机对应的第一相机移动距离。
在一些实施方式中，在得到第一相机移动距离和第一相机移动方向之后，计算机设备可以根据第一相机移动距离和第一相机移动方向来移动虚拟相机，从而使得虚拟相机在不 同的位置拍摄被拍摄物体，从而在图形用户界面中呈现出虚拟场景对应的画面。
120、响应于对视角控件的状态切换操作，切换视角控件处于第二操控模式。
在一些实施方式中，计算机设备可以响应于对视角控件的在预设时长内的至少两次按下操作，则将视角控件的第一操控模式切换为第二操控模式。
例如，在视角控件的图标内，用户连续按下两次，且这两次按下操作均在预设时长内，则确定触发视角控件的第二操控模式的触发条件，则用户可以通过第二操控模式来操控视角控件来切换虚拟场景中的虚拟场景的拍摄视角。其中，触发操作还可以是点击、按压等其他操作。
在一些实施方式中，当接收到视角控件的第二操控模式的触发条件时，将视角控件的第一操控模式的第一显示图标切换为第二操控模式的第二显示图标；将视角控件的第一操控模式的第一操控逻辑切换为第二操控模式的第二操控逻辑。
通过视角控件对应的图标切换来提醒用户视角控件的操控模式进入了第二操控模式。
需要说明的是，第二操控逻辑和第一操控逻辑时不同的，视角控件对应的控制方式也发生改变。
计算机设备可以获取用户针对于视角控件的触控操作，例如用户在视角控件的控制区域内，通过滑动、拖动的方式来进行第二移动操作，计算机从而捕获第二移动参数。
130、在视角控件处于第二操控模式下，响应于针对视角控件的默认区域中的第二移动操作，根据第二移动操作获取虚拟相机在虚拟场景的景深方向上的第二移动参数，根据第二移动参数控制虚拟相机在虚拟场景的景深方向上移动。
在一些实施方式中，计算机设备可以确定第二移动操作当前在默认区域内的第一触控点；确定第一触控点与视角控件的默认区域内第一参考点之间的第二操作移动距离，以及从第一参考点至第一触控点的第二操作移动方向；根据第二操作移动距离和第二操作移动方向确定虚拟相机在虚拟场景的景深方向上的第二移动参数。其中，第二移动参数包括第二相机移动方向和第二相机移动距离。
具体地，计算机设备可以根据第二操作移动距离确定虚拟相机在虚拟场景的景深方向上的第二相机移动距离。例如，可以根据预设的比例关系，来计算出第二操作移动距离对应的第二相机移动距离。
具体地，计算机设备可以根据第二操作移动方向与相机前后移动方向的预设映射关系，将第二操作移动方向映射为虚拟相机虚拟场景的景深方向上的第二相机移动方向，其中，若第二相机移动方向与虚拟相机的拍摄方向相反，则虚拟相机按照第二相机移动距离向后移动，若第二相机移动方向与虚拟相机的拍摄方向相同，则虚拟相机按照第二相机移动距离向前移动。
例如，用户在触控屏幕的时候，在屏幕上进行上下滑动时，当第二操作移动方向为向上滑动，则虚拟相机对应的移动方向为在景深方向上朝向被拍摄物体移动。当第二操作移动方向为向下滑动，则虚拟相机对应的移动方向为在景深方向上背向被拍摄物体移动。
可以理解的是，在第二操控模式下，通过第二相机移动距离和第二相机移动方向来对虚拟相机进行操控，从而控制虚拟相机和被拍摄物体之间的距离。
例如，若增大虚拟相机的焦距，则第二画面中被拍摄主体在第二画面中的占比相对于原画面中被拍摄主体在原画面中的占比更大。若缩小虚拟相机的焦距，则第二画面中被拍摄主体在第二画面中的占比相对于原画面中被拍摄主体在原画面中的占比更小。
因此，在本申请实施例中，可以通过触发第二操控模式的情况下，通过对视角控件的操作，从而实现控制虚拟相机改变与被拍摄物体之间的距离，从而实现改变焦距，从而使得虚拟相机拍摄出虚拟场景中被拍摄物体对应的画面。
由上述内容可知，在本申请实施例中，通过设置一个视角控件来赋予不同的操控模式，从而在不同的操控模式下，用户可以通过该视角控件调整虚拟相机的拍摄角度，从而得到 不同视角下的虚拟场景中的画面，从而提升了视角切换的效率。
需要说明的是，在本申请实施例中，对于视角控件控制的过程，可以是在一种游戏编辑过程，还可以是一种游戏编辑的场景，比如对游戏中的某一画面进行拍摄，即可用于对游戏场景的拍摄。当然，还可以用于对游戏场景中的游戏角色的视角控制，还可以应用于单独对游戏场景的视角控制，在此不作限制。
相当于一种游戏编辑过程/场景，不是一般的游戏运行场景当中游戏视角的控制。
本申请实施例中，在视角控件处于第一操控模式下，响应于在视角控件的默认区域中的第一移动操作，根据第一移动操作获取虚拟相机在所处竖直平面上的第一移动参数，根据第一移动参数控制虚拟相机在所处竖直平面移动；响应于对视角控件的状态切换操作，切换视角控件处于第二操控模式；在视角控件处于第二操控模式下，响应于针对视角控件的默认区域中的第二移动操作，根据第二移动操作获取虚拟相机在虚拟场景的景深方向上的第二移动参数，根据第二移动参数控制虚拟相机在虚拟场景的景深方向上移动。从而实现通过一个视角控件实现不同的操控模式，从而呈现出虚拟场景的不同视角的画面，提高了视角控制的效率。
为了更加详细的说明本申请实施例所提供的视角切换方法，请继续参阅图2，图2是本申请另一可选实施例提供的视角切换方法的流程示意图，该视角切换方法可以包括如下步骤：
201、在视角控件处于第一操控模式下，响应于在视角控件的默认区域中的第一移动操作，获取第一移动操作的第一操作移动距离和第一操作移动方向。
在一些实施方式中，视角控件对应有多种操控模式，每一操控模式下的视角控件的图标有所不同。视角控件默认的操控模式为第一操控模式，当视角控件的操控模式为第一操控模式时，则用户操控视角控件时，计算机设备可以捕获视角控件的第一移动参数。
例如，当视角控件的操控模式为第一操控模式时，用户可以通过点击、拖动、滑动等方式来操控视角控件，从而在视角控件的默认区域中进行第一移动操作。其中视角控件的默认区域可以理解为是一个图标区域，比如视角控件的图标是圆形的，则默认区域则为该视角控件的圆形图标区域。
在一些实施方式中，当视角控件的操控模式为第一操控模式时，视角控件对应的操控逻辑为第一操控模式的第一操控逻辑，即用户操作视角控件时，按照第一操控逻辑来实现控制视角。
在一些实施方式中，当视角控件的操控模式为第一操控模式时，视角控件对应的图标为第一显示图标，第一显示图标有助于用户了解视角控件当前对应的操控模式。
请一并参阅图4，是本申请一可选实施例提供的视角控件的示意图。
其中，当视角控件的操控模式为第一操控模式时，视角控件的显示图标为第一显示图标。
在用户操控视角控件的时候，视角控件有对应的触控点，该触控点可以是用户通过手指触摸触控显示屏所生成的触控点，该触控点还可以是用户通过鼠标等外设在屏幕上生成的触控点。
其中，通过第一移动操作获取第一移动参数，第一移动操作包含了视角控件对应的触控点的第一操作移动距离和第一操作移动方向。例如，当视角控件的操控模式为第一操控模式时，可以获取用户对视角控件进行操作的初始触控点和最终触控点，然后从初始触控点到最终触控点，从而获取触控点的第一操作移动距离和第一操作移动方向。
需要说明的是，当视角控件的操控模式为第一操控模式时，针对于视角控件操作的触控点在视角控件对应的预设范围内，该预设范围内为视角控件对应的默认区域。比如视角控件为圆形图标，该圆形图标的半径为R，那么预设范围可以是该圆形图标的圆心为中心、半径范围为R的圆形范围。具体可以根据实际视角操作需求而设定。又或者，该圆形图标 的范围就是预设范围。在此仅做例举，不对本申请做出限制。
如图4所示，若以中心点为初始触控点，当用户在预设范围内的最终触控点在初始触控点的正上方时，即图4中的Y轴正方向时，此时第一操作移动方向就是Y轴正方向，第一操作移动距离就是最终触控点的Y轴坐标值减去初始触控点的Y轴坐标值。
若以中心点为初始触控点，当用户在预设范围内的最终触控点在初始触控点的正右方时，即图4中的X轴正方向时，此时第一操作移动方向就是X轴正方向，第一操作移动距离就是最终触控点的X轴坐标值减去初始触控点的X轴坐标值。
202、根据第一操作移动距离和第一操作移动方向，确定虚拟相机在所处竖直平面的第一相机移动方向和第一相机移动距离，第一移动参数包括第一相机移动方向和第一相机移动距离。
在一些实施方式中，计算机设备可以获取第一移动操作的第一操作移动距离和第一操作移动方向；根据第一操作移动距离和第一操作移动方向，确定虚拟相机在所处竖直平面的第一相机移动方向和第一相机移动距离，其中第一移动参数包括第一相机移动距离和第一相机移动方向。
在一些实施方式中，计算机设备可以根据第一移动距离确定出虚拟相机在虚拟场景中对应比例的第一相机移动距离；将第一移动方向确定为虚拟相机在虚拟场景中的第一相机移动方向；根据第一相机移动距离和第一相机移动方向控制虚拟相机在所处的竖直平面内移动，从而使得虚拟相机拍摄出第一画面。
例如，当第一操控模式下，在三维的虚拟场景中，虚拟相机在竖直平面内移动，比如虚拟相机面对拍摄物体，虚拟相机在竖直平面内进行上下左右移动。比如虚拟相机的移动方向和虚拟相机的拍摄方向垂直。
此时，计算机设备可以建立虚拟相机移动时对应的平面坐标系，然后移动距离和移动方向设置在该平面坐标系中，从而得到移动距离和移动方向对应的向量。然后获取该向量在坐标轴上对应的分向量，然后将分向量的方向垂直于虚拟相机的拍摄方向的分向量确定为目标分向量，然后确定出目标分向量的方向为虚拟相机对应的第一相机移动方向，然后将目标分向量的模乘以对应的比例，则得到虚拟相机对应的第一相机移动距离。
203、根据第一移动参数控制虚拟相机在所处竖直平面移动。
在一些实施方式中，在得到第一相机移动距离和第一相机移动方向之后，计算机设备可以根据第一相机移动距离和第一相机移动方向来移动虚拟相机，从而使得虚拟相机在不同的位置拍摄被拍摄物体，从而在图形用户界面中呈现出虚拟场景对应的画面。
在一些实施方式中，可以在虚拟相机在所属的竖直平面内根据第一相机移动距离和第一相机移动方向来控制虚拟相机移动。虚拟相机从而拍摄训场景得到第一画面，计算机设备通过图形用户界面展示该第一画面。
在一些实施场景中，第一画面相对于原画面，仅仅是实现了画面平移，即如果一个被拍摄物体在原画面左侧，则平移虚拟相机之后，第一画面中被拍摄物体在右侧。
请一并参阅图5和图6，图5是本申请一可选实施例提供的虚拟相机的示意图。图6是本申请另一可选实施例提供的虚拟相机的示意图。
若触控点的移动方向为沿着X轴方向移动，那么垂直于X轴的虚拟相机被控制左右移动。
若触控点的移动方向为沿着Y轴方向移动，那么垂直于Y轴的虚拟相机被控制上下移动。
也就是说，第一操控模式下，可以控制虚拟相机沿着垂直于拍摄方向的平面内来移动，从而实现视角的切换。
204、响应于对视角控件的状态切换操作，切换视角控件处于第二操控模式。
在一些实施方式中，计算机设备可以响应于对视角控件的在预设时长内的至少两次按 下操作，则将视角控件的第一操控模式切换为第二操控模式。
例如，在视角控件的图标内，用户连续按下两次，且这两次按下操作均在预设时长内，则确定触发视角控件的第二操控模式的触发条件，则用户可以通过第二操控模式来操控视角控件来切换虚拟场景中的虚拟场景的拍摄视角。其中，触发操作还可以是点击、按压等其他操作。
在一些实施方式中，当接收到视角控件的第二操控模式的触发条件时，将视角控件的第一操控模式的第一显示图标切换为第二操控模式的第二显示图标；将视角控件的第一操控模式的第一操控逻辑切换为第二操控模式的第二操控逻辑。
通过视角控件对应的图标切换来提醒用户视角控件的操控模式进入了第二操控模式。
在一些实施方式中，还可以通过其他方式来触发第二操控模式的触发条件，例如，当按压压力值大于预设压力值的时候，则触发第二操控模式的触发条件。当按压面积大于预设按压面积的时候，则触发第二操控模式的触发条件。在此不作限制。
需要说明的是，第二操控逻辑和第一操控逻辑时不同的，视角控件对应的控制方式也发生改变。
计算机设备可以获取用户针对于视角控件的触控操作，例如用户在视角控件的控制区域内，通过滑动、拖动的方式来进行第二移动操作，计算机从而捕获第二移动参数。
需要说明的是，第二移动操作和状态切换操作连续。
205、在视角控件处于第二操控模式下，响应于针对视角控件的默认区域中的第二移动操作，确定第二移动操作当前在默认区域内的第一触控点。
在一些实施方式中，在第二操控模式下获取用户在视角控件的默认区域内的第一触控点，该第一触控点可以是视角控件的默认区域内当前最新的触控点。
206、确定第一触控点与视角控件的默认区域内第一参考点之间的第二操作移动距离，以及从第一参考点至第一触控点的第二操作移动方向。
请一并参阅图7，图7是本申请另一可选实施例提供的视角控件的示意图。
其中，在默认区域内设置有第一参考点，该第一参考点可以是默认区域的预设位置点，比如第二显示图标的中心点。或者，第一参考点可以是第二移动操作在默认区域内的初始触控点。第一触控点可以是默认区域内的最终触控点。第一触控点还可以是默认区域内当前的触控点。
计算机设备可以确定第一触控点与视角控件的默认区域内第一参考点之间的第二操作移动距离，以及从第一参考点至第一触控点的第二操作移动方向。
207、根据第二操作移动距离确定虚拟相机在虚拟场景的景深方向上的第二相机移动距离。
在一些实施方式中，计算机设备可以根据第二操作移动距离确定虚拟相机在虚拟场景的景深方向上的第二相机移动距离。例如，可以根据预设的比例关系，来计算出第二操作移动距离对应的第二相机移动距离。
比如，第二操作移动距离和第二相机移动距离之间的比例为10:1，若第二操作移动距离为10，则第二相机移动距离为1。
208、根据第二操作移动方向与相机前后移动方向的预设映射关系，将第二操作移动方向映射为虚拟相机虚拟场景的景深方向上的第二相机移动方向。
具体地，计算机设备可以根据第二操作移动方向与相机前后移动方向的预设映射关系，将第二操作移动方向映射为虚拟相机虚拟场景的景深方向上的第二相机移动方向，其中，若第二相机移动方向与虚拟相机的拍摄方向相反，则虚拟相机按照第二相机移动距离向后移动，若第二相机移动方向与虚拟相机的拍摄方向相同，则虚拟相机按照第二相机移动距离向前移动。
例如，用户在触控屏幕的时候，在屏幕上进行上下滑动时，当第二操作移动方向为向 上滑动，则虚拟相机对应的移动方向为在景深方向上朝向被拍摄物体移动。当第二操作移动方向为向下滑动，则虚拟相机对应的移动方向为在景深方向上背向被拍摄物体移动。
其中，第二移动参数包括第二相机移动距离和第二相机移动方向。
209、根据第二移动参数控制虚拟相机在虚拟场景的景深方向上移动。
可以理解的是，在第二操控模式下，通过第二相机移动距离和第二相机移动方向来对虚拟相机进行操控，从而控制虚拟相机和被拍摄物体之间的距离。
例如，若增大虚拟相机的焦距，则第二画面中被拍摄主体在第二画面中的占比相对于原画面中被拍摄主体在原画面中的占比更大。若缩小虚拟相机的焦距，则第二画面中被拍摄主体在第二画面中的占比相对于原画面中被拍摄主体在原画面中的占比更小。
在一些实施方式中，在第二操控模式下，若用户是在视角控件对应的默认区域内操控的，则第二操控逻辑为在默认区域内滑动可以控制虚拟相机和被拍摄物体之间的焦距发生改变，从而捕获到第二画面。
若第二相机移动方向与虚拟场景中的虚拟相机的拍摄方向相反，则根据第二相机移动距离控制虚拟相机增大焦距，以拍摄虚拟场景，得到第二画面。
计算机设备可以通过获取第二相机移动方向在Y轴方向上的分量，若虚拟相机的拍摄方向和Y轴正方向相同，且第二相机移动方向在Y轴方向上的分量与虚拟相机的拍摄方向相反，则确定第二相机移动方向与虚拟场景中的虚拟相机的拍摄方向相反，则根据焦距参数控制虚拟相机增大焦距，以拍摄虚拟场景，得到第二画面。
请一并参阅图8，图8是本申请另一可选实施例提供的虚拟相机的示意图。
若虚拟相机增大与被拍摄物体之间的焦距，则虚拟相机的位置从上一位置发生改变，从而向下移动，从而增大虚拟相机与被拍摄对象之间的焦距。从而得到第二画面。
若第二相机移动方向与虚拟场景中的虚拟相机的拍摄方向相同，则根据第二相机移动距离控制虚拟相机缩小焦距，以拍摄虚拟场景，得到第二画面。
如图8所示，若第一方向与虚拟场景中的虚拟相机的拍摄方向相同，则虚拟相机缩小焦距，虚拟相机的位置从上一位置发生改变，从而向上移动，从而缩小虚拟相机与被拍摄对象之间的焦距。从而得到第二画面。
在一些实施方式中，在视角控件处于第一操控模式或者第二操控模式下，响应于对视角控件的旋转参数输入操作，根据第三移动操作在默认区域外的移动方向确定虚拟相机在虚拟场景中的旋转方向。
具体参阅图3，图3是本申请另一可选实施例提供的视角切换方法的流程示意图。该视角切换方法可以包括如下步骤：
301、在视角控件处于第一操控模式或者第二操控模式下，响应于对视角控件的旋转参数输入操作，根据第三移动操作在默认区域外的移动方向确定虚拟相机在虚拟场景中的旋转方向。
旋转参数输入操作包括在默认区域外的第三移动操作。
旋转参数输入操作的触发条件可以是用户从视角控件的默认区域内滑动至默认区域外，且在默认区域外来实现旋转参数的输入操作。例如，在第一操控模式下或第二操作模式下，用户从默认区域内的操作该换位默认区域外的操作，此时，计算机设备触发视角控件的第三操控模式。
在一些实施方式中，计算机设备可以根据第三移动操作在默认区域外的移动方向确定虚拟相机在虚拟场景中的旋转方向。例如，在默认区域外，可以通过触控点的运动轨迹来确定出旋转方向，比如触控点的运动轨迹为逆时针方向，则旋转方向为逆时针方向。若触控点的运动轨迹为顺时针方向，则旋转方向为顺时针方向。
302、获取第三移动操作在默认区域外初始的第二触控点和当前的第三触控点。
请一并参阅图9，图9是本申请实施例提供的视角控件的第三示意图。
其中点A为第二参考点，点B为第二触控点，点C为第三触控点，第二触控点和第三触控点均在默认区域之外。第二参考点A包括：默认区域的预设位置点，或者，状态切换操作的初始触控点。
其中第二触控点为默认区域外的初始的触控点，比如用户在默认区域内开始触控操作，然后滑动至默认区域外，在默认区域外第一次停顿之后，从而确定出第二触控点。然后用户在默认区域外进行滑动，直至到第三触控点，第三触控点为默认区域外的当前触控点。
在一些实施方式中，第三移动操作与状态切换操作连续。
303、确定在旋转方向上默认区域内的第二参考点到第二触控点的连线与到第三触控点的连线的夹角，根据夹角确定虚拟相机在虚拟场景中的旋转角度。
如图9所示，以第二参考点为原点，连接参考点和第二触控点，以及连接参考点和第三触控点，从而得到角BAC，角BAC的角度为D，那么角度D就是第二触控点和第三触控点之间的角度，将角度D确定为旋转角度。
在一些实施方式中，第三移动操作在第二触控点处的移动方向，与状态切换操作的初始触控点和结束触控点的连线之间的角度，满足预设角度条件时，第三移动操作有效。
例如，当视角空间的默认区域为圆形区域时，第二触控点和第三触控点之间的连线与该圆形区域之间的切线方向之间的角度在预设角度范围内时，则确定第三操作有效。比如该角度大于或等于a1且小于或等于a2，其中a1小于90度，a2大于90度。
304、根据旋转方向和旋转角度控制虚拟相机在虚拟场景中旋转。
请一并参阅图10，图10是本申请另一可选实施例提供的虚拟相机的示意图。
若旋转方向为顺时针方向，则控制虚拟场景中的虚拟相机顺时针旋转角度，以拍摄虚拟场景。
其中，若旋转方向为顺时针方向，则控制虚拟场景中的虚拟相机顺时针旋转角度，即角度R1和上述中的角度D是相同的。
若旋转方向为逆时针方向，则控制虚拟场景中的虚拟相机逆时针旋转角度，以拍摄虚拟场景。
其中，若旋转方向为逆时针方向，则控制虚拟场景中的虚拟相机逆时针旋转角度，即角度R2和上述中的角度D是相同的。
由上述可知，在本申请实施例中，可以通过一个视角控件来实现控制虚拟相机来进行多个角度的画面采集，从而实现视角控制。
本申请实施例中，在视角控件处于第一操控模式下，响应于在视角控件的默认区域中的第一移动操作，根据第一移动操作获取虚拟相机在所处竖直平面上的第一移动参数，根据第一移动参数控制虚拟相机在所处竖直平面移动；响应于对视角控件的状态切换操作，切换视角控件处于第二操控模式；在视角控件处于第二操控模式下，响应于针对视角控件的默认区域中的第二移动操作，根据第二移动操作获取虚拟相机在虚拟场景的景深方向上的第二移动参数，根据第二移动参数控制虚拟相机在虚拟场景的景深方向上移动。从而实现通过一个视角控件实现不同的操控模式，从而呈现出虚拟场景的不同视角的画面，提高了视角控制的效率。
从而实现了通过一个视角控件实现多种视角控制，提升了视角切换的效率，同时因为只有一个视角控件，对虚拟场景的遮挡较少。
