在虚拟环境中进行视角调整的方法、装置及可读存储介质
本申请要求于2018年04月16日提交的申请号为201810339749.7、发明名称为“在虚拟环境中进行视角调整的方法、装置及存储介质”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
本申请实施例涉及计算机图形处理领域，特别涉及一种在虚拟环境中进行视角调整的方法、装置及可读存储介质。

通常，在上述应用程序的用户界面中，用户可以通过左手控制摇杆控件以及在右侧屏幕进行滑动对虚拟对象进行控制，其中，摇杆控件用于控制虚拟对象在朝向不变的情况下进行前进、后退、左移或者右移等操作，而在右侧屏幕用于对虚拟对象在虚拟环境中面朝的方向(也即视角方向)进行旋转。
然而，通过上述方式对虚拟对象的视角进行旋转时，同时也改变了虚拟对象的状态，即在旋转视角的过程中虚拟对象的模型也需要在虚拟环境中同时进行转动，也即虚拟对象的朝向也进行旋转，则虚拟对象在行走或者奔跑状态下时，旋转视角会改变虚拟对象行走或者奔跑的方向，造成用户对虚拟环境的观察时操作较为不便。

本申请实施例提供的技术方案带来的有益效果至少包括:
通过设置视角调整控件，当用户在第一用户界面上对视角调整控件进行控制时，可以达到对观察虚拟环境的视角方向进行调整而不改变虚拟对象的朝向的效果，即在虚拟对象维持原有的人物朝向，保持原有运动姿态的同时，用户可以通过控制视角调整控件对虚拟环境的其他视角方向进行观察，也即，用户不会因为对其他视角方向进行观察而改变虚拟对象在虚拟环境中的行进方向，提高了用户对虚拟环境进行观察时的便捷程度，避免了视角调整操作与虚拟对象的运动轨迹之间相互影响。

在一个可选的实施例中，该第一视角方向是在虚拟环境中通过摄像机模型对虚拟对象进行观察时的方向，图7是本申请另一个示例性的实施例提供的在虚拟环境中进行视角调整的方法流程图，如图7所示，该在虚拟环境中进行视角调整的方法包括：

步骤702，接收对视角调整控件的拖动指令。
可选地，在接收到拖动指令后，还可以对虚拟对象的第一朝向进行锁定操作，该锁定操作用于控制虚拟对象的第一朝向不被改变。
步骤703，确定拖动指令的拖动方向。
可选地，用户在对视角调整控件进行拖动时，可以对视角调整控件向用户界面的平面中的任意方向进行拖动，示意性的，请参考图8及图9，图8及图9是对拖动方向进行确定的两种划分方式，图8中以将视角调整控件81向左拖动为0°，按顺时针方向对角度递增直至360°，图9中以将视角调整控件91向左拖动为0°，按顺时针方向对角度递增直至180°，按逆时针方向对角度递减直至-180°。
步骤704，根据拖动指令将摄像机模型以虚拟对象为旋转中心，以拖动方向对应的方向为旋转方向，在虚拟环境中进行旋转。
可选地，该拖动指令还用于指示拖动距离，该拖动指令的拖动距离与摄像机模型在转动过程中的转动角度呈正相关关系。
可选地，摄像机模型的旋转方向与拖动方向相对应，以摄像机模型在旋转中心为球心的球面上进行旋转为例进行说明，首先根据拖动指令在球面上作过摄像机模型的与该拖动方向对应的圆，并根据拖动指令对摄像机模型在该圆上作顺时针旋转或者逆时针旋转。
值得注意的是，上述摄像机模型在虚拟环境中进行旋转的过程中，不仅有摄像机模型角度上的转动，还有该摄像机模型在虚拟环境中由旋转而产生的位移。
示意性的，请参考图10，图10是本实施例一个具体地摄像机模型根据拖动指令进行旋转的举例，如图10所示，在用户界面1010中包括视角调整控件1020以及具有第一朝向的虚拟对象1030，用户对视角调整控件1020向右边进行拖动操作，结合上述图8或者图9可知，用户将该视角调整控件1020向180°方向进行拖动，由于该180°方向在虚拟环境中对应水平方向，在摄像机模型1041所在的球面作一个水平方向的圆，根据拖动方向为180°，将摄像机模型1041在该圆上沿顺时针进行转动，并根据拖动距离确定转动角度，如：拖动距离每1 个单位时，将摄像机模型1041沿旋转角度转动15°，本实施例中，以摄像机模型1041旋转至摄像机模型1042的位置为例。
步骤705，将旋转后的摄像机模型对虚拟环境进行观察的视角方向确定为第二视角方向。
示意性的，结合图10可知，将旋转后的摄像机模型1042对虚拟对象1030进行观察的方向确定为第二视角方向。
可选地，当检测到摄像机模型在旋转过程中存在阻碍时，将该摄像机模型被阻碍时的视角方向确定为第二视角方向。
其中，摄像机模型在旋转过程中存在阻碍的可能性包括如下情况中的至少一种：
第一，在摄像机模型的旋转过程中被穿帮检测限制，其中，穿帮检测是指在虚拟环境中根据物理原理对虚拟对象能否对旋转后的视角方向进行观察进行检测，当检测到摄像机模型在旋转过程中被穿帮检测限制旋转时，将被穿帮检测限制时的视角方向确定为第二视角方向；
可选地，该穿帮检测是指在摄像机模型的旋转过程中，当该摄像机模型不被障碍物阻挡时，虚拟对象能否对旋转后的视角方向进行观察进行检测，如：摄像机模型在旋转过程中，从窗口之外转动到窗口内，以对房间的内部进行观察，而根据物理原理，虚拟对象在其所处的位置无法对房间内进行观察时，则认为该摄像机模型在旋转过程中被穿帮检测限制旋转。
第二，在摄像机模型旋转的过程中被障碍物阻挡，该障碍物是在该虚拟环境中三维模型，当检测到摄像机模型在旋转过程中存在障碍物阻挡时，将摄像机模型被障碍物阻挡时的视角方向确定为第二视角方向。
可选地，摄像机模型在旋转过程中是否被障碍物阻挡可以通过在虚拟环境中进行碰撞检测进行检测。由于在虚拟环境中，可以对物体与物体之间进行碰撞检测，如：按照摄像机模型的旋转路径进行碰撞检测，判断该摄像机模型在旋转过程中是否会与障碍物进行碰撞，当摄像机模型在旋转过程中会与障碍物碰撞时，认为该摄像机模型被障碍物阻挡。
步骤706，显示第二视角画面，该第二视角画面是在虚拟环境中以第二视角方向观察虚拟对象时的画面。
可选地，该第二视角画面中包括上述具有第一朝向的虚拟对象。可选地，该第二视角画面上也叠加显示有该视角调整控件。
示意性的，结合图10，如用户界面1050所示，旋转后的摄像机模型1042对虚拟对象进行观察时的第二视角画面中包括该具有第一朝向的虚拟对象1030，以及在该第二视角画面上还叠加显示有视角调整控件1020。
可选地，此时用户对该视角调整控件1020依旧处于拖动状态，该拖动状态可以是暂停拖动状态，即持续对视角调整控件1020进行触摸，但暂停拖动，也可以是持续拖动状态。
可选地，在从第一视角画面向第二视角画面过渡的过程中，显示第三视角画面，该第三视角画面为通过将第一视角方向调整至第二视角方向的过程中的过渡视角方向观察虚拟环境时的画面。根据拖动指令将第三视角画面上叠加显示的视角调整控件在预设平移范围内沿拖动方向进行平移显示。请参考图10，将视角调整控件1020在预设平移范围内(框住该视角调整控件的虚线圆形范围内)进行平移显示，如：当拖动方向向右时，将视角调整控件向右平移直至到虚拟圆形的边缘位置。
综上所述，本实施例提供的在虚拟环境中进行视角调整的方法，通过设置视角调整控件，当用户在第一用户界面上对视角调整控件进行控制时，可以达到对观察虚拟环境的视角方向进行调整而不改变虚拟对象的朝向的效果，即在虚拟对象维持原有朝向，保持原有运动姿态的同时，用户可以通过控制视角调整控件对虚拟环境的其他视角方向进行观察，也即，用户不会因为对其他视角方向进行观察而改变虚拟对象在虚拟环境中的行进方向，提高了用户对虚拟环境进行观察的便捷程度。
本实施例提供的在虚拟环境中进行视角调整的方法，通过摄像机模型对虚拟环境中的虚拟对象进行观察，通过摄像机模型将虚拟对象的朝向与对虚拟环境的观察方向两者分离进行，用户可以通过控制视角调整控件旋转摄像机模型。对虚拟环境的其他视角方向进行观察，提高了用户对虚拟环境进行观察的便捷程度。
在一个可选的实施例中，在当检测到拖动指令停止时，终端将第二视角方向再调整至第一视角方向，请参考图11，图11是本申请另一个示例性的实施例提供的在虚拟环境中进行视角调整的方法流程图，该在虚拟环境中进行视角调整的方法包括：

步骤1102，接收对视角调整控件的拖动指令。
可选地，在接收到拖动指令后，还可以对虚拟对象的第一朝向进行锁定操作，该锁定操作用于控制虚拟对象的第一朝向不被改变。
步骤1103，确定拖动指令的拖动方向。
可选地，用户在对视角调整控件进行拖动时，可以对视角调整控件向用户界面的平面中的任意方向进行拖动，确定拖动指令的拖动方向已在步骤703中进行了具体说明，此处不再赘述。
步骤1104，根据拖动指令将摄像机模型以虚拟对象为旋转中心，以拖动方向对应的方向为旋转方向，在虚拟环境中进行旋转。
可选地，该拖动指令还用于指示拖动距离，该拖动指令的拖动距离与摄像机模型在转动过程中的转动角度呈正相关关系。
可选地，摄像机模型的旋转方向与拖动方向相对应，以摄像机模型在旋转中心为球心的球面上进行旋转为例进行说明，首先根据拖动指令在球面上作过摄像机模型的与该拖动方向对应的圆，并根据拖动指令对摄像机模型在该圆上作顺时针旋转或者逆时针旋转。
步骤1105，将旋转后的摄像机模型对虚拟环境进行观察的视角方向确定为第二视角方向。
步骤1106，显示第二视角画面，该第二视角画面是在虚拟环境中以第二视角方向观察虚拟对象时的画面。
可选地，该第二视角画面中包括上述具有第一朝向的虚拟对象。可选地，该第二视角画面上也叠加显示有该视角调整控件。
步骤1107，检测对视角调整控件的拖动指令。
可选地，该拖动指令的状态可以包括：拖动指令持续、拖动指令暂停或者拖动指令停止。其中，拖动指令持续是指用户对视角调整控件进行持续拖动， 拖动指令暂停是指用户对该视角调整控件持续进行触摸(或按压或点击)但暂停对该视角调整控件的拖动，拖动指令停止是指用户停止对该视角调整控件的触摸(或按压或点击)，也停止对该视角调整控件的拖动。
步骤1108，当检测到拖动指令停止时，将第二视角方向沿预设轨迹自动调整至第一视角方向。
可选地，将第二视角方向沿预设轨迹自动调整至第一视角方向时，至少包括如下方式中的任意一种：
第一，记录从第一视角方向旋转至第二视角方向时的旋转路径，根据该旋转路径将第二视角方向沿该旋转路径旋转至第一视角方向；
第二，获取第二视角方向旋转至第一视角方向的最短旋转路径，并根据该最短旋转路径将第二视角方向旋转至第一视角方向。
其中，将第二视角方向调整至第一视角方向是将摄像机模型从第二位置旋转至第一位置。其中，第二位置为摄像机模型以第二视角方向观察虚拟环境时的位置，第一位置为摄像机模型以第一视角方向观察虚拟环境时的模型。
步骤1109，当虚拟对象的状态为站立状态或蹲下状态或趴下状态时，显示第一视角画面。
当虚拟对象的状态为站立状态或者蹲下状态或者趴下状态时，该虚拟对象在虚拟环境中的位置和朝向都没有发生改变，故将第二视角方向调整至第一视角方向后，直接显示第一视角画面。
步骤1110，当虚拟对象的状态为持续奔跑、持续步行、驾驶载具、乘坐载具中的任意一个时，显示更新后的第一视角画面。
该更新后的第一视角画面是以第一视角方向观察虚拟对象时，由于虚拟对象在虚拟环境中的移动而更新的画面，该更新后的第一视角画面中包括朝向第一方向的虚拟对象。由于虚拟对象在虚拟环境中的移动，虚拟对象在虚拟环境中的位置可能发生改变，所以，第一视角画面会随着虚拟对象在虚拟环境中的位置发生改变而进行更新。
当虚拟对象的状态为持续奔跑、持续步行、驾驶载具、乘坐载具中的任意一个时，该虚拟对象在虚拟环境中的朝向没有发生改变，但是虚拟对象在虚拟环境中的位置发生了变化，故将第二视角方向调整至第一视角方向后，显示更新后的第一视角画面。
综上所述，本实施例提供的在虚拟环境中进行视角调整的方法，通过设置 视角调整控件，当用户在第一用户界面上对视角调整控件进行控制时，可以达到对观察虚拟环境的视角方向进行调整而不改变虚拟对象的朝向的效果，即在虚拟对象维持原有朝向，保持原有运动姿态的同时，用户可以通过控制视角调整控件对虚拟环境的其他视角方向进行观察，也即，用户不会因为对其他视角方向进行观察而改变虚拟对象在虚拟环境中的行进方向，提高了用户对虚拟环境进行观察的便捷程度。
本实施例提供的在虚拟环境中进行视角调整的方法，通过摄像机模型对虚拟环境中的虚拟对象进行观察，通过摄像机模型将虚拟对象的朝向与对虚拟环境的观察方向两者分离进行，用户可以通过控制视角调整控件旋转摄像机模型。对虚拟环境的其他视角方向进行观察，提高了用户对虚拟环境进行观察的便捷程度。
本实施例提供的在虚拟环境中进行视角调整的方法，当检测到拖动指令停止时，将第二视角方向沿预设轨迹自动调整至第一视角方向，用户可以通过停止对视角调整控件进行拖动或者停止对视角调整控件进行触摸，将视角方向还原至第一视角方向，提高了用户对虚拟环境进行观察的便捷程度。
图12是本申请另一个示例性的实施例提供的在虚拟环境中进行视角调整的方法流程图，该在虚拟环境中进行视角调整的方法包括：
步骤1201，生成视角调整控件。
首先，终端判断该应用程序中的视角调整控件是否被开启，当该视角调整控件被开启时，生成视角调整控件，并将其叠加显示在视角画面之上。
步骤1202，判断视角调整控件是否被按下。
步骤1203，当视角调整控件被按下时，锁定虚拟对象的朝向，判断拖动方向。
当视角调整控件被按下时，说明用户需要对虚拟环境的其他角度进行观察，但需要虚拟对象保持现有朝向，则锁定该虚拟对象的朝向，并判断拖动操作的拖动方向。
步骤1204，摄像机模型朝向虚拟对象并跟随虚拟对象。
摄像机模型始终保持对虚拟对象进行观察的角度，并跟随该虚拟对象，即，当虚拟对象在运动过程中时，摄像机模型跟随该虚拟对象，并围绕该虚拟对象进行旋转。
步骤1205，摄像机模型向拖动方向对应的方向进行旋转。
具体旋转过程在上述步骤704中已进行了说明，此处不再赘述。
步骤1206，停止对视角调整控件的拖动后，还原摄像机模型的观察方向。
即将摄像机模型的观察方向还原至未对视角调整控件进行按下之前的观察方向。
步骤1207，遇到无意义视角时，进行摄像机自动跟随，显示合理内容。
在摄像机模型的旋转过程中，持续检测旋转得到的视角是否是无意义视角，该无意义视角即根据物理原理无法达到的视角。当旋转后的视角是无意义视角时，控制摄像机模型的视角不继续向该无意义视角进行旋转。
示意性的，该无意义视角可以是摄像机模型旋转至墙壁内的视角，或者摄像机模型旋转至地面之下的视角，或者摄像机模型旋转至窗口内观察房间内的虚拟环境时的视角，而根据物理原理，虚拟对象在所处的位置无法对房间内的虚拟环境进行观察。
可选地，在用户界面中包括两种操作，如图13所示：步骤1301，生成视角调整控件。步骤1302，判断是拖动视角区域还是拖动视角调整控件。步骤1303，当拖动视角调整控件时，摄像头模型与虚拟对象的朝向独立。步骤1304，虚拟对象的移动不改变。步骤1305，当拖动视角区域时，摄像头模型与虚拟对象的朝向同步，保持追尾视角。
即对视角区域进行拖动以及对视角调整控件进行拖动分为如下两种情况：
第一，拖动视角区域，即摄像机模型的观察视角与用户的朝向进同步，当对观察视角进行调整时，用户跟对摄像机模型的旋转进行转身操作，并摄像机模型对虚拟对象保持追尾视角，可选地，该视角区域可以是用户界面的左半边或者右半边，也可以是预先设定的一块区域；
第二，拖动视角调整控件，摄像机模型与虚拟对象的朝向独立，虚拟对象的移动不受改变。
