具体实施方式
虚拟场景：是应用程序在终端上运行时显示(或提供)的虚拟的场景。该虚拟场景可以是对真实世界的仿真环境场景，也可以是半仿真半虚构的三维环境场景，还可以是纯虚构的三维环境场景。虚拟场景可以是二维虚拟场景、2.5维虚拟场景和三维虚拟场景中的任意一种，下述实施例以虚拟场景是二维虚拟场景或者三维虚拟场景来举例说明，但对此不加以限定。
虚拟场景通常由终端等计算机设备中的应用程序生成，并基于终端中的硬件(比如屏幕)进行显示。该终端可以是智能手机、平板电脑或者电子书阅读器等移动终端；或者，该终端也可以是笔记本电脑或者固定式计算机的个人计算机设备。
策略游戏：策略游戏是一种模拟战略游戏(Simulation Game，SLG)的衍生游戏类型(或分支)。当模拟游戏的模拟对象不单单是一种物体(如载具)时，玩家就需要在进行游戏时保证自己的模拟对象达成游戏规定的目标。而模拟游戏一般都较为自由和开放，所以玩家就需要在游戏认可的限度(游戏规则)内想尽办法完成目标。这催生了全新的游戏类型——策略游戏。因为模拟游戏一般都较为自由和开放，所以玩家就需要在游戏认可的限度(游戏规则)内，运用智慧来进行游戏。
策略游戏提供给玩家一个可以动脑筋思考问题来处理较复杂事情的环境，允许玩家自由控制、管理和使用游戏中的人、或事物，通过这种自由的手段，以及玩家们开动脑筋想出的对抗敌人的办法，来达到游戏所要求的目标。
策略游戏本身的含义非常广泛，只要玩家需运用策略完成游戏所给的目标获得胜利，即可算作策略游戏。从这个意义上来说，大多数益智游戏都是策略游戏。策略游戏所包含的“策略”一般都较为复杂。每一款策略游戏都不单单是为了“益智”，战术分部、心理战、机会利用都是策略游戏注重表现的。
策略游戏按照规模划分，可以分为战略游戏和战术游戏；按照进行方式划分，可以分为回合制策略游戏和即时策略游戏(Real-Time Strategy Game，RTS)；按照主题划分，可以分为战术射击游戏、抽象策略游戏、策略角色扮演游戏、模拟角色扮演游戏、益智游戏等等。
请参考图1，其示出了本申请一个实施例提供的虚拟场景显示系统的示意图。该系统可以包括：第一终端110、服务器120。
第一终端110安装和运行有支持虚拟场景的应用程序111，该应用程序111可以是多人在线对战程序。当第一终端运行应用程序111时，第一终端110的屏幕上显示应用程序111的用户界面。该应用程序111可以是策略游戏。第一终端110是第一用户112使用的终端，第一用户112使用第一终端110控制位于虚拟场景中的第一虚拟对象进行游戏，第一虚拟对象可以称为第一用户112的主控虚拟对象。示意性的，第一虚拟对象是第一虚拟人物，比如仿真人物或动漫人物。
图1中仅示出了一个终端，但在不同实施例中存在多个其它终端可以接入服务器120。可选地，还存在一个或多个终端是开发者对应的终端，在该终端上安装有支持虚拟场景的应用程序的开发和编辑平台，开发者可在该终端上对应用程序进行编辑和更新，并将更新后的应用程序安装包通过有线或无线网络传输至服务器120，第一终端110可以从服务器120下载应用程序安装包实现对应用程序的更新。
第一终端110以及其它终端通过无线网络或有线网络与服务器120相连。
服务器120包括一台服务器、多台服务器组成的服务器集群、云计算平台和虚拟化中心中的至少一种。
在一个示意性的例子中，服务器120包括存储器121、处理器122、用户账号数据库123、游戏服务模块124、面向用户的输入/输出接口(Input/Output Interface，I/O接口)125。其中，处理器122用于加载服务器120中存储的指令，处理用户账号数据库123和游戏服务模块124中的数据；用户账号数据库123用于存储第一终端110以及其它终端所使用的数据，比如头像、昵称、战斗力指数、所在的服务区；游戏服务模块124用于提供多个游戏场景供用户进行游戏，比如1V1游戏、3V3游戏、5V5游戏等；面向用户的I/O接口125用于通过无线网络或有线网络和第一终端110和/或其它终端建立通信交换数据。
其中，虚拟场景可以是三维虚拟场景，或者，虚拟场景也可以是二维虚拟场景，也就是说，虚拟场景的表现形式可以在二维和三维之间切换。以虚拟场景是二维虚拟场景为例，请参考图2，其示出了本申请一个示例性的实施例提供的虚拟场景界面示意图。如图2所示，虚拟场景界面中包含场景画面200，该场景画面200中包括虚拟场景中可见的各项元素，比如，城市210、山地220、资源点230以及林地240等等。
用户可以控制当前的虚拟对象进行管理类的游戏活动，比如城市建设、资源采集、人员管理、发起对战等等。
在本申请后续的各个实施例中，虚拟场景提供二维变现形式和三维表现形式，并且，虚拟场景的场景画面在显示过程中，在二维变现形式和三维表现形式之间切换。
请参考图3，其示出了本申请一个示例性的实施例提供的一种虚拟场景显示方法的流程示意图。其中，上述方法可以由计算机设备执行，该计算机设备可以是终端，也可以是服务器，或者，上述计算机设备也可以包含上述终端和服务器。如图3所示，计算机设备可以通过执行以下步骤来控制虚拟场景的显示。
步骤301，显示虚拟场景界面，该虚拟场景界面用于显示虚拟场景的场景画面。
步骤302，在该虚拟场景界面中，以第一表现形式显示该虚拟场景的第一场景画面；该第一表现形式是二维表现形式或者三维表现形式。
步骤303，响应于接收到对该虚拟场景的缩放操作，在该虚拟场景界面中，以第二表现形式显示该虚拟场景的第二场景画面；该第二表现形式是二维表现形式和三维表现形式中，除了该第一表现形式之外的另一种表现形式。
其中，上述该虚拟场景的缩放操作，是指对采集该虚拟场景中的场景画面的虚拟镜头的拉近/拉远的操作。
其中，对虚拟镜头执行拉近操作时，虚拟场景中的场景元素的尺寸在场景画面中增大，细节增加，相应的，虚拟场景界面中显示的该虚拟场景的可见范围会缩小，相当于对虚拟场景的显示比例尺进行放大。
反之，对虚拟镜头执行拉远操作时，虚拟场景中的场景元素的尺寸在场景画面中缩小，细节减少，相应的，虚拟场景界面中显示的该虚拟场景的可见范围会变大，相当于对虚拟场景的显示比例尺进行缩小。
在一种可能的实现方式中，响应于接收到对该虚拟场景的缩放操作，且该缩放操作满足指定条件，在该虚拟场景界面中，以第二表现形式显示该虚拟场景的第二场景画面。
在一种可能的实现方式中，上述缩放操作满足指定条件，可以包括以下情况中的至少一种：
1)虚拟相机的高度在缩放操作前后的变化情况满足条件；其中，虚拟相机的高度，用于控制所述虚拟场景的场景画面的视野范围。
例如，上述虚拟相机用于采集虚拟场景的场景画面。上述虚拟相机的高度，用于指示虚拟相机与虚拟场景在同一个三维坐标系中的垂直坐标系上的距离；在虚拟相机的视野角度不变的情况，虚拟相机的高度越高，能够拍摄到的该虚拟场景的范围(也就是虚拟场景的场景画面的视野范围)也越大，反之，虚拟相机的高度越低，能够拍摄到的该虚拟场景的范围也越小。
2)缩放操作的操作速率满足条件。
例如，当缩放操作时滑动触摸操作时，缩放操作的操作速率可以是滑动触摸操作的滑动速率。
3)缩放操作的操作幅度满足条件。
例如，当缩放操作时滑动触摸操作时，缩放操作的操作幅度可以是滑动触摸操作的滑动距离。
在本申请实施例中，虚拟场景的应用程序对应虚拟场景提供两种不同表现形式的显示方式(二维和三维)，并且，在以虚拟场景这个单一对象为目标进行画面显示的过程中，用户可以通过对虚拟场景的缩放操作，使得虚拟场景的场景画面在二维表现形式和三维表现形式之间进行切换。
例如，当虚拟场景界面中以二维表现形式显示场景画面时，若接收到满足条件的放大操 作，则说明用户需要观察更加细节的场景画面，此时，可以将场景画面切换至三维表现形式，以提高细节显示效果，若接收到满足条件的缩小操作，则说明用户需要更广阔的视野范围，此时，可以将场景画面切换至二维表现形式，以降低终端资源消耗，保证画面流畅度。
综上所述，本申请实施例所示的方案，在虚拟场景界面中以二维表现形式或三维表现形式显示场景画面的情况下，可以在对虚拟场景的缩放操作的触发下，将虚拟场景的场景画面切换至二维表现形式和三维表现形式中的另一种表现形式；上述过程中，不需要用户退出场景画面进行设置，只需要复用对虚拟场景的缩放操作，即可以实现对场景画面的表现形式的灵活切换，从而显著的降低用户操作过程的复杂度，提高了虚拟场景的表现形式的切换效率。
以上述缩放操作满足指定条件包括虚拟相机的高度在缩放操作前后的变化情况满足条件为例，请参考图4，其示出了本申请一个示例性的实施例提供的虚拟场景显示方法的方法流程图。其中，上述方法可以由计算机设备执行，该计算机设备可以是终端，也可以是服务器，或者，上述计算机设备也可以包含上述终端和服务器。如图4所示，以计算机设备是终端为例，终端可以通过执行以下步骤来控制虚拟场景的显示。
步骤401，显示虚拟场景界面，该虚拟场景界面用于显示虚拟场景的场景画面。
在本申请实施例中，当虚拟场景的应用程序启动时，可以首先显示虚拟场景界面，该虚拟场景界面用于显示虚拟场景的场景画面。可选的，该虚拟场景界面中还可以叠加显示一个或多个操作控件。
步骤402，在该虚拟场景界面中，以第一表现形式显示该虚拟场景的第一场景画面；该第一表现形式是二维表现形式或者三维表现形式。
在本申请实施例中，上述虚拟场景可以提供两种表现形式，即二维表现形式和三维表现形式。
其中，二维表现形式，是指以二维图像显示虚拟场景的场景画面；三维表现形式，是指以三维图像显示虚拟场景的场景画面。
步骤403，响应于接收到对该虚拟场景的缩放操作，获取虚拟相机在该缩放操作前后的高度变化信息。
其中，该虚拟相机用于采集该虚拟场景的场景画面；该虚拟相机的高度用于控制该虚拟场景的场景画面的视野范围。
在一种可能的实现方式中，上述高度变化信息包括虚拟相机在缩放操作之前的高度，以及虚拟相机在缩放操作之后的高度。
可选的，上述高度变化信息还包括以下信息中的至少一种：高度变化的速率、高度变化量等等。
在一种可能的实现方式中，当上述缩放操作是对虚拟场景的放大操作时，虚拟场景对应的应用程序可以降低虚拟相机的高度；反之，当上述缩放操作是对虚拟场景的缩小操作时，虚拟场景对应的应用程序可以增加虚拟相机的高度。
在本申请实施例中，上述对该虚拟场景的缩放操作，可以是在虚拟场景界面中执行的滑动触摸操作。比如，该缩放操作可以是双指/三指滑动操作；例如，双指/三指向内聚拢滑动的操作，是对虚拟场景的缩小操作；而双指/三指向外分散滑动的操作，是对虚拟场景的放大操作。
或者，上述对该虚拟场景的缩放操作，可以是对指定控件的触发操作。比如，指定控件可以包括缩小控件和放大控件，对缩小控件的点击/按压操作，是对虚拟场景的缩小操作；而对放大控件的点击/按压操作，是对虚拟场景的放大操作。再比如，指定控件可以包括滑动条件，在滑动条件上向不同方向的滑动操作，分别是对虚拟场景的缩小操作和放大操作。
步骤404，响应于该高度变化信息满足第一高度变化条件，在该虚拟场景界面中，以第二表现形式显示该第二场景画面。
其中，该第二表现形式是二维表现形式和三维表现形式中，除了该第一表现形式之外的另一种表现形式。
在一种可能的实现方式中，上述高度变化信息满足第一高度变化条件，可以包括情况中的至少一种：
1)虚拟相机的高度所在的高度区间的变化满足条件。
在本申请实施例中，当虚拟相机的高度从一个区间变化到另一个区间时，可以触发虚拟场景的场景画面在二维表现形式和三维表现形式之间的转换。
比如，响应于该高度变化信息指示该虚拟相机的高度，从该第一表现形式的高度区间变化至该第二表现形式的高度区间，确定该高度变化信息满足该第一高度变化条件。
在本申请实施例的一个示例性的方案中，虚拟场景界面中的显示对象(或者说是画面内容)，与虚拟相机的相机状态相关，而虚拟相机的相机状态，可以由虚拟相机的高度确定。
例如，虚拟场景界面中的显示对象可以包括三种，即虚拟场景的地图、整体的虚拟场景、以及虚拟场景中的某个场景元素(比如虚拟场景中的一座城市、一座山川、一块林地或者一处矿藏等等)，也就是说，在不同的虚拟相机的高度下，虚拟相机所拍摄的对象是不同的。
例如，请参考图5至图7，其示出了本申请实施例涉及的虚拟相机的高度与拍摄对象的示意图。如图5所示，当虚拟相机的高度大于9000时，虚拟相机所拍摄的对象可以是虚拟场景的地图51(对应相机状态为地图显示状态)；如图6所示，当虚拟相机的高度处于区间[3250，7000]时，虚拟相机所拍摄的对象可以是整体的虚拟场景61(对应相机状态为虚拟场景显示状态)；如图7所示，当虚拟相机的高度小于3000时，虚拟相机所拍摄的对象可以是虚拟场景中的某个场景元素71(对应相机状态为场景元素显示状态)。
如图6所示，在本申请实施例中，对于虚拟相机所拍摄的对象是整体的虚拟场景的情况，对相机状态进一步划分，也就是将虚拟场景显示状态划分为二维虚拟场景显示状态和三维虚拟场景显示状态；例如，当虚拟相机的高度处于区间[3250，4500]时，虚拟相机所拍摄的对象可以是三维虚拟场景(对应相机状态为三维虚拟场景显示状态)；当虚拟相机的高度处于区间[4700，7000]时，虚拟相机所拍摄的对象可以是二维虚拟场景(对应相机状态为二维虚拟场景显示状态)。
在一种可能的实现方式中，在应用程序中，相机状态可以通过相机状态等级来表示，例如，场景元素显示状态对应相机状态等级1，三维虚拟场景显示状态对应相机状态等级2，二维虚拟场景显示状态对应相机状态等级3，地图显示状态对应相机状态等级4。虚拟相机的高度变化时，相机状态会增序切换或者降序切换。
在本申请实施例中，当虚拟相机所拍摄的对象是整体的虚拟场景时，虚拟相机的高度所处的区间变化，可以触发场景画面的表现形式的切换；例如，当虚拟相机的高度在上述缩放操作的控制下，从区间[3250，4500]增加至区间[4700，7000]内时，触发虚拟场景画面从三维场景画面(第一场景画面)，切换至二维场景画面(第二场景画面)；反之，当虚拟相机的高度在上述缩放操作的控制下，从区间[4700，7000]降低至区间[3250，4500]内时，触发虚拟场景画面从二维场景画面(第一场景画面)，切换至三维场景画面(第二场景画面)。
例如，请参考图8，其示出了本申请实施例涉及的相机高度与表现形式示意图。如图8所示，在策略游戏中，随着玩家在屏幕上执行缩放手势，虚拟相机81会沿着Z轴移动，如果玩家在屏幕做手势缩小操作。虚拟相机81的Z坐标值增大，虚拟相机81的可视范围会逐步扩大，当虚拟相机81的Z坐标进入到2D表现视野时，会自动为玩家将表现形式切换到2D表现形式。反之，用户执行缩小手势，虚拟相机81的Z坐标值变小，虚拟相机81的可视范围缩小，当虚拟相机81的Z坐标进入到3D表现视野时，表现切换成3D表现形式。
虚拟相机2D和3D表现相关的参数可以在应用程序的代码中设置。例如，以CameraZMinValue和CameraZMaxValue分别对应当前表现形式的相机Z轴最大最小值。
当前虚拟相机处于WorldCameraStatLevel2(即上述相机状态等级2)这个状态。如果虚 拟相机的Z轴继续增加，那么当Z值大于当前状态下的CameraMoveMaxValue(即上述4500)这个值的时候，虚拟相机将会切换到WorldCameraStatLevel3(即上述相机状态等级3)这个状态。反向操作同样如此，如果相机的Z值小于相机状态等级3下的CameraMoveMinValue(即上述4700)这个值，虚拟相机的相机状态将从WorldCameraStatLevel3切换到WorldCameraStatLevel2。
每个相机状态对应了相应的表现，比如近景相机，是针对查看主城细节的，也就是上述相机状态等级1。普通3D相机是渲染3D表现的相机，具有和2D场景不同的相机设置，3D场景常用的是透视相机。相机状态等级3通常是战略地图相机状态，使用的是正交相机，在缩放的时候，修改的参数也可以不同。相机状态等级4是世界地图的相机状态，也可以是一个正交相机。
2)虚拟相机的高度变化速率满足条件。
在本申请实施例中，当虚拟相机的高度的变化速率满足一定条件时，可以触发虚拟场景的场景画面在二维表现形式和三维表现形式之间的转换。
例如，当虚拟相机的高度变化速率大于速率阈值，且上述缩放操作控制虚拟相机的高度增加(即上述缩放操作是缩小操作)时，触发虚拟场景的场景画面从三维表现形式向二维表现形式转换；或者，当虚拟相机的高度变化速率大于速率阈值，且上述缩放操作控制虚拟相机的高度降低(即上述缩放操作是放大操作)时，触发虚拟场景的场景画面从二维表现形式向三维表现形式转换。
3)虚拟相机的高度变化值满足条件。
在本申请实施例中，当虚拟相机的高度的变化速率满足一定条件时，可以触发虚拟场景的场景画面在二维表现形式和三维表现形式之间的转换。
例如，当虚拟相机的高度变化值大于高度变化阈值，且上述缩放操作控制虚拟相机的高度增加(即上述缩放操作是缩小操作)时，触发虚拟场景的场景画面从三维表现形式向二维表现形式转换；或者，当虚拟相机的高度变化值大于高度变化阈值，且上述缩放操作控制虚拟相机的高度降低(即上述缩放操作是放大操作)时，触发虚拟场景的场景画面从二维表现形式向三维表现形式转换。
在本申请实施例中，虚拟场景对应的应用程序在该虚拟场景界面中，以第二表现形式显示该虚拟场景的第二场景画面时，可以响应于接收到该缩放操作，激活该第二表现形式的数据资源管理组件；通过该第二表现形式的数据资源管理组件，基于该虚拟相机在该缩放操作之后的高度，在该虚拟场景界面中以该第二表现形式显示该第二场景画面。
在一种可能的实现方式中，虚拟场景对应的应用程序还可以控制该第一表现形式的数据资源管理组件转入非激活状态；并销毁该第一表现形式的数据资源管理组件管理的数据资源。
在本申请实施例中，虚拟场景对应的应用程序在启动时，可以启动两个数据资源管理组件，分别对应2D表现形式和3D表现形式，并且，这两个数据资源管理组件中的一个处于激活状态，用于显示虚拟场景对应的场景画面。此外，由于两种表现形式的数据资源并不通用，因此，在一个数据资源管理组件处于激活状态时，为了节约内存资源，可以将另一个未激活状态的数据资源管理组件管理的数据资源销毁。
请参考图9，其示出了本申请实施例涉及的一种常见的显示模型示意图。如图9所示，在常见的显示模型90中，根据当前虚拟相机所见区域加载模型并显示，最终交由图形处理器绘制到屏幕显示。
请参考图10，其示出了本申请实施例涉及的显示模型示意图。在该方案中，由于同时支持两种表现形式的切换，因此重新设计了显示模型。首先强化viewport(视窗1001)的功能，即视窗会根据虚拟相机当前的位置计算出玩家所有可见到的地图网格。计算之后可以不对网格内容做任何逻辑处理，而是会将这个数据继续传递到数据资源管理组件层进行操作。
如图10所示，在虚拟相机切换状态时，会修改虚拟相机的状态，比如从3D相机状态切 换到2D相机状态，此时可以注销掉当前的3D虚拟场景的显示(即注销3D表现形式对应的数据资源管理组件1002)，然后执行2D的虚拟场景的载入(即激活2D表现形式对应的数据资源管理组件1003)，之后所有的表现都会在2D的数据资源管理组件中执行，并交由图形处理器渲染，最终显示到屏幕，反之亦然。
在一种可能的实现方式中，响应于该第一表现形式的数据资源管理组件保持在非激活状态的时长达到第一时长阈值，销毁该第一表现形式的数据资源管理组件管理的数据资源。
用户在使用虚拟场景对应的应用程序的过程中，可能会在短时间内，在两种表现形式的场景画面之间频繁切换，相应的，虚拟场景对应的应用程序也需要反复加载和销毁数据资源，从而影响显示效果，比如，频繁造成卡顿。
对于这种情况，在本申请实施例中，虚拟场景对应的应用程序在控制场景画面在2D和3D之间切换后，可以在一段时间内保留切换前的数据资源，如果用户在短时间内又切换回之前的表现形式，则可以避免数据资源的重复加载和销毁，如果一段时间之后用户未切换回之前的表现形式，则将之前的数据资源销毁，以节约内存空间。
在一种可能的实现方式中，在激活该第二表现形式的数据资源管理组件之前，虚拟场景对应的应用程序还可以响应于该高度变化信息满足第二高度变化条件，预加载该第二表现形式对应的数据资源管理组件管理的数据资源；其中，该第二高度变化条件包括：该高度变化信息指示该虚拟相机的高度处于该第一表现形式的高度区间内，且该虚拟相机的高度与该第二表现形式的高度区间之间的最小高度距离小于距离阈值。
由于场景画面的表现形式在2D和3D之间切换时，需要进行数据资源管理组件的激活，以及数据资源的加载，这会产生一定的时延，从而影响画面切换的流畅性。
对于上述问题，在本申请实施例中，可以实行数据资源的预加载，来减少不同表现形式的画面切换之间的时延。例如，当虚拟相机的高度处于当前相机状态所在的高度区间内(比如处于2D对应的高度区间[4700，7000]内)，但是又接近另一相机状态所在的高度区间(比如，相机高度为4800，接近3D对应的高度区间[3250，4500])，此时，虚拟场景对应的应用程序可以预加载3D数据资源管理组件管理的数据资源，以降低数据加载对画面切换造成的时延，提高流畅性。
在一种可能的实现方式中，该第二高度变化条件还包括：该高度变化信息指示该虚拟相机的高度向该第二表现形式的高度区间变化。
由于预加载资源数据会占用一部分内存资源，为了避免不必要的预加载过程，在本申请实施例中，虚拟场景对应的应用程序还可以结合虚拟相机的高度变化的方向，来确定是否预加载。例如，当高度变化信息指示该虚拟相机的高度向该第二表现形式的高度区间变化时，表示可能即将要切换到第二表现形式，此时执行预加载；反之，如果高度变化信息指示该虚拟相机的高度向该第二表现形式的高度区间的相反方向变化，则表示不会切换到第二表现形式，此时不执行预加载。
在一种可能的实现方式中，在通过该第二表现形式的数据资源管理组件，基于该虚拟相机在该缩放操作之后的高度，在该虚拟场景界面中以该第二表现形式显示该第二场景画面时，可以基于该虚拟相机在该缩放操作之后的高度，确定该虚拟场景中对用户可见的目标区块；通过该第二表现形式的数据资源管理组件，在静态数据中加载与该目标区块对应的，该第二表现形式的目标数据资源；基于该目标数据资源，在该虚拟场景界面中以该第二表现形式显示该第二场景画面。
在虚拟场景的制作过程中，美术人员会生成虚拟场景显示所需要的所有数据。请参考图11，其示出了本申请实施例涉及的虚拟场景数据配置示意图。如图11所示，美术人员构建虚拟场景(S1101)，生成虚拟场景对应的静态数据(S1102)，然后将全部的静态数据按照虚拟场景进行切块压缩存储(S1103)，每块压缩数据对应虚拟场景中一个区块。
在美术侧制作完游戏场景之后，由于同时存在两种表现形式的数据，需要对各种表现形 式的数据进行二次处理，包括数据索引，资源分类，为之后的运行时资源加载和表现渲染提供离线静态数据。
在此基础上，需要解决由于两个表现形式的数据量增大的问题，本申请所示的方案采用了分块存储的方式，请参考图12，其示出了本申请实施例涉及的一种场景切块示意图。如图12所示，可以将虚拟场景按照地图1201切分成大小相等的区块1202。
之后将分块数据进行序列化成二进制文件，并压缩存储。这样就可以解决运行时静态数据在内存中消耗过高的问题，运行时根据玩家视窗所在区域反向操作之前的数据。请参考图13，其示出了本申请实施例涉及的静态数据加载示意图。如图13所示，在虚拟相机的高度发生变化时，视窗计算出对用户可视区域覆盖的目标区块(S1301)，判断已有的静态数据是否可用(S1302)，即判断静态数据中是否包含目标区块对应的数据资源，若是，则直接使用静态数据进行画面显示(S1303)，否则，加载目标区块对应的压缩文件(S1304)，解压缩(S1305)后进行反序列化(S1306)，并添加至静态数据，并使用静态数据进行画面显示。
在一种可能的实现方式中，响应于该静态数据中包含该目标数据资源之外的其它资源，将该其它资源从该静态数据中删除。
在本申请实施例中，为了节约内存资源，对于显示当前画面的目标数据资源之外的其它数据资源，虚拟场景的应用程序可以将这部分数据资源删除。
在一种可能的实现方式中，响应于该其它资源未被使用的时长达到第二时长阈值，将该其它资源从该静态数据中删除。
在本申请实施例中，为了避免用户在短时间内来回调整虚拟相机的高度而导致相同的数据资源被反复删除和加载的情况，虚拟场景的应用程序在删除静态数据中未被使用的数据资源时，可以将静态数据中未被使用的时长达到第二时长阈值的数据删除，而未被使用的时长没有达到第二时长阈值的数据则继续保留。
在一种可能的实现方式中，上述第一表现形式的高度区间，以及该第二表现形式的高度区间，可以是开发人员预先设置的，或者，由用户预先设置的。
在一种可能的实现方式中，虚拟场景的应用程序可以获取显示该虚拟场景界面的终端的性能参数，该性能参数用于指示该终端的图形显示性能；基于该性能参数，获取高度区间划分信息；该高度区间划分信息包括该第一表现形式的高度区间，以及该第二表现形式的高度区间。
在本申请实施例中，为了兼顾不同性能的终端的虚拟场景显示效果，虚拟场景的应用程序可以针对不同性能的终端，确定不同的高度区间划分信息。例如，对于图形显示性能较高的终端，虚拟场景的应用程序可以设置较为宽泛的三维表现形式的高度区间，比如[3250，5500]，而对于图形显示性能较低的终端，虚拟场景的应用程序可以设置较为窄的三维表现形式的高度区间，比如[3250，4000]。
在一种可能的实现方式中，该第一表现形式为二维表现形式，该第二表现形式为三维表现形式，该缩放操作是对该虚拟场景的放大操作。
例如，请参考图14，其示出了本申请实施例涉及的一种虚拟场景放大示意图。虚拟场景的应用程序可以显示虚拟场景界面，该虚拟场景界面用于显示虚拟场景的场景画面；在该虚拟场景界面中，以二维表现形式显示该虚拟场景的第一场景画面1401；响应于接收到对该虚拟场景的放大操作，且放大后的该虚拟场景的场景画面的视野范围小于范围阈值，以三维表现形式显示该虚拟场景的第二场景画面1402。
在另一种可能的实现方式中，第一表现形式为三维表现形式，该第二表现形式为二维表现形式，该缩放操作是对该虚拟场景的缩小操作。
例如，请参考图15，其示出了本申请实施例涉及的一种虚拟场景缩小示意图。虚拟场景的应用程序可以显示虚拟场景界面，该虚拟场景界面用于显示虚拟场景的场景画面；在该虚拟场景界面中，以三维表现形式显示该虚拟场景的第一场景画面1501；响应于接收到对该虚 拟场景的缩小操作，且缩小后的该虚拟场景的场景画面的视野范围大于范围阈值，以二维表现形式显示该虚拟场景的第二场景画面1502。
综上所述，本申请实施例所示的方案，在虚拟场景界面中以二维表现形式或三维表现形式显示场景画面的情况下，可以在对虚拟场景的缩放操作的触发下，将虚拟场景的场景画面切换至二维表现形式和三维表现形式中的另一种表现形式；上述过程中，不需要用户退出场景画面进行设置，只需要复用对虚拟场景的缩放操作，即可以实现对场景画面的表现形式的灵活切换，从而显著的降低用户操作过程的复杂度，提高了虚拟场景的表现形式的切换效率。
图16是本申请一个示例性实施例提供的虚拟场景显示装置的结构框图，该装置可以用于执行如图3或图4所示的方法中的全部或者部分步骤，该装置包括：
界面显示模块1601，用于显示虚拟场景界面，所述虚拟场景界面用于显示虚拟场景的场景画面；
第一画面显示模块1602，用于在所述虚拟场景界面中，以第一表现形式显示所述虚拟场景的第一场景画面；所述第一表现形式是二维表现形式或者三维表现形式；
