具体实施方式
首先，对本申请实施例中涉及的名词进行介绍：
主控对象：是指用户控制的以第一人称视角观察虚拟环境的可活动对象。该可活动对象可以是虚拟人物、虚拟动物、动漫人物等，比如：在虚拟环境中显示的人物、动物、植物、油桶、墙壁、石块等。可选地，当虚拟环境为三维虚拟环境时，虚拟对象是基于动画骨骼技术创建的三维立体模型，每个虚拟对象在三维虚拟环境中具有自身的形状和体积，占据三维虚拟环境中的一部分空间。可选地，当虚拟环境为二维虚拟环境时，虚拟对象是基于动画技术创建的二维平面模型，每个虚拟对象在二维虚拟环境中具有自身的形状和面积，占据二维虚拟环境中的一部分面积。
FPS(First Person Shooting game)游戏：是一种在虚拟世界中提供若干个据点，处于不同阵营的用户控制虚拟角色在虚拟世界中对战，占领据点或摧毁敌对阵营据点或击杀敌对 阵营全部或部分角色的游戏。通常，FPS游戏中用户以第一人称视角进行游戏。例如，FPS游戏可将用户分成两个敌对阵营，将用户控制的虚拟角色分散在虚拟世界中互相竞争，以击杀敌方的全部虚拟角色作为胜利条件。FPS游戏以局为单位，一局FPS游戏的持续时间是从游戏开始的时刻至达成胜利条件的时刻。
图1示出了本申请一个示例性实施例提供的计算机系统100的结构示意图。计算机系统100包括：终端120和服务器140。
终端120上安装有支持虚拟环境的应用程序。该应用程序可以是FPS游戏、竞速游戏、MOBA(Multiplayer Online Battle Arena，多人在线战术竞技游戏)游戏、虚拟现实应用程序、三维地图程序、多人枪战类生存游戏中的任意一种。用户使用终端120操作位于虚拟环境中的主控对象进行活动，该活动包括但不限于：攻击、释放技能、购买道具、治疗、调整身体姿态、爬行、步行、骑行、飞行、跳跃、驾驶、拾取、射击、投掷中的至少一种。示意性的，第一虚拟角色是第一虚拟人物。终端120是智能手机、平板电脑、电子书阅读器、MP3播放器、MP4播放器、膝上型便携计算机和台式计算机中的至少一种。
终端120通过无线网络或有线网络与服务器140相连。
服务器140可以是独立的物理服务器，也可以是多个物理服务器构成的服务器集群或者分布式系统，还可以是提供云服务、云数据库、云计算、云函数、云存储、网络服务、云通信、中间件服务、域名服务、安全服务、CDN(Content Delivery Network，内容分发网络)、以及大数据和人工智能平台等基础云计算服务的云服务器。服务器140用于为支持虚拟环境的应用程序提供后台服务。可选地，服务器140承担主要计算工作，终端120承担次要计算工作；或者，服务器140承担次要计算工作，终端120承担主要计算工作；或者，服务器140和终端120两者采用分布式计算架构进行协同计算。
相关技术在显示主控对象时，会按照如下步骤实现，如图2所示：
匹配动画姿势201：确定主控对象的不同部位的动画姿势。匹配动画姿势201用于确定主控对象的动画姿势。可选地，主控对象在活动时，确定主控对象的动画姿势。示例性的，活动包括但不限于走、跑、跳、站、蹲、趴、攻击、飞行、驾驶、拾取、射击、投掷中的至少一种。可选地，匹配动画姿势201会匹配主控对象不同部位的动画姿势，比如，主控对象边射击边跑，则需要为主控对象的上半身匹配射击的动画姿势，为主控对象的下半身匹配跑的动画姿势。
叠加动画202：将主控对象的不同部位的动画姿势进行叠加，得到主控对象的动画姿势。叠加动画202用于处理主控对象不同部位的动画叠加。示例性的，将主控对象的上半身的动画姿势与下半身的动画姿势进行叠加，得到主控对象的动画姿势。
骨骼变形203：调整主控对象的骨骼模型，得到变形后的骨骼模型。骨骼变形203用于调整主控对象的骨骼形状。可选地，骨骼变形203的方式包括但不限于改变骨骼位置、改变骨骼朝向和缩放骨骼比例中的至少一种。示例性的，一方面，在显示主控对象时，为了防止主控对象的头部穿模，会缩放主控对象头部的骨骼。另一方面，在主控对象进行左右探身时，会对主控对象进行过量扭曲，使得主控对象能够完成探身这一动作。如图3所示，以第三人称视角观察主控对象301时，主控对象301的头部被缩放(去除)，且主控对象301的身体处于过量扭曲的状态。
调整姿势204：基于主控对象的当前状态，调整变形后的骨骼模型的姿势。调整姿势204用于调整主控对象的姿势以提高精确度。示例性的，通过反向动力学调整主控对象手部的姿势，以提高主控对象持握道具的精确度。
在完成调整姿势204后，会输出主控对象的本体模型205，本体模型205用于生成主控对象的本体。
需要说明的是，显示主控对象的本体的方法并不能直接移植到显示主控对象的投影上， 示例性的，若是采用上述方法来生成主控对象的投影则会得到如图4所示的投影401，投影401的形状明显和实际不符。这是由于骨骼变形203这一步骤会引起主控对象的骨骼变形，一方面将主控对象的头部缩放了，另一方面对主控对象进行了扭曲，导致主控对象的骨骼与实际不同。但是在生成主控对象的本体模型时不能跳过骨骼变形203这一步骤，如果跳过骨骼变形203这一步骤，一方面，如果在骨骼变形203中没有缩放头部，会导致主控对象的头部和主控对象的摄像机模型相互影响，造成穿模的现象。另一方面，当主控对象进行左右探身时，如果不对主控对象进行足够扭曲，则难以实现主控对象的探身。
因此，相关技术会在计算机设备中运行两个不同的进程来分别实现主控对象的本体和投影的显示。示例性的，如图5所示，第一进程501用于生成主控对象的本体，第二进程502用于生成主控对象的投影。但是，发明人发现，这里又会引起其他问题，由于需要对一个主控对象计算两份不同的进程，且前述两个进程无法通过降频等其他方式进行优化，对于那些计算能力有限的计算机设备而言，比如手机，是无法通过这种方式来同时显示主控对象的本体和投影。而且，对于那些计算能力较强的计算机设备而言，也容易因为线程等待而导致进程处理时间过长。
为了解决上述问题：1、主控对象的本体和主控对象的投影的实现方式不兼容，需要两套不同的方法才能分别得到主控对象的本体和主控对象的投影；2、同时生成主控对象的本体和主控对象的投影要求计算机设备具有较强的计算能力，部分计算能力较弱的终端并不能实现同时生成主控对象的本体和主控对象的投影。
图6示出了本申请一个实施例提供的生成主控对象投影的方法的流程示意图。该方法可由图1所示的终端120执行，该方法包括以下步骤：
步骤602：从主控对象的本体动画蓝图中提取主控对象的原始骨骼模型，主控对象是以第一人称视角观察虚拟环境的对象，本体动画蓝图用于生成虚拟环境中主控对象的本体模型，原始骨骼模型是主控对象的未经过骨骼变形的模型。
主控对象可以是虚拟人物、虚拟动物、动漫人物中的至少一种。本申请对此不作具体限定。示例性的，用户在FPS游戏中操控主控对象，用户以第一人称视角控制主控对象。
可选地，本体动画蓝图包括骨骼变形处理，骨骼变形处理用于避免主控对象穿模而修改主控对象的骨骼。示例性的，当主控对象的骨骼模型进行骨骼变形后，会缩放主控对象的头部骨骼，此时的模型不适合用于生成主控对象的投影，因此，将使用未经过骨骼变形的模型作为原始骨骼模型。
可选地，本体动画蓝图包括如图2所示实施例所示的步骤。
本体动画蓝图是生成虚拟环境中主控对象的本体模型的流程(或者，也可称为本体动画蓝图是生成虚拟环境中主控对象的本体的流程)。通过本体动画蓝图可以得到主控对象的本体。主控对象的本体指虚拟环境中的主控对象。
步骤604：基于原始骨骼模型得到投影模型，投影模型是用于生成主控对象在虚拟环境中的投影的模型。
在一个实施例中，将原始骨骼模型直接作为投影模型。需要说明的是，因为主控对象的投影精度往往要求不高，当更侧重终端性能时，即可直接将原始骨骼模型作为投影模型。
在一个实施例中，基于主控对象的当前状态，调整原始骨骼模型的姿势，得到投影模型。需要说明的是，若进一步追求主控对象的投影的精度，则可以根据主控对象的当前状态，对原始骨骼模型进一步调整。
可选地，当前状态包括但不限于攻击、释放技能、购买道具、治疗、调整身体姿态、爬行、步行、骑行、飞行、跳跃、驾驶、拾取、射击、投掷、跑步、静止中的至少一种。示例性的，若主控对象处于步行状态，则将原始骨骼模型的姿势调整为步行姿势。
可选地，当主控对象的状态发生变化时，基于变化后的状态，调整原始骨骼模型的姿 势，得到投影模型。示例性的，主控对象由静止状态变化为跑步状态，则将主控对象由静止姿势变化为跑步姿势。
可选地，基于周期性变化调整原始骨骼模型的姿势。比如，主控对象在步行状态下，双脚交替移动，故基于双脚周期性的交替移动，改变原始骨骼模型的姿势。
示例性的，基于主控对象的当前状态，采用反向动力学调整原始骨骼模型的姿势，得到投影模型。
需要说明的是，出于投影的性质，主控对象的投影的本身精度较低，因此可以取消对原始骨骼模型的姿势调整操作，姿势调整操作用于提升主控对象的投影的精度。比如，当主控对象在小角度转身时，存在脚步逻辑调整，脚步逻辑调整用于提升表现的细腻程度，但是由于主控对象的投影的精度较低，即使进行了脚步逻辑调整也不会体现出来，因此可以取消脚步逻辑调整，以降低计算机设备的计算量。
因此，在一些实际场景，可以减少对原始骨骼模型的姿势调整的步骤，比如，取消上述脚步逻辑调整，或者，取消手部细节调整。
步骤606：渲染投影模型，得到主控对象的投影。
可选地，主控对象的投影是主控对象本体在虚拟环境中背光侧的投影。示例性的，主控对象的投影是虚拟环境中地面上的投影，或者，主控对象的投影是虚拟环境中墙壁上的投影，或者，主控对象的投影是虚拟环境中天花板上的投影。
可选地，主控对象的投影还可以指反射面上的图像。例如，主控对象的投影指镜面上主控对象的图像，又例如，主控对象的投影指水面上主控对象的图像。
示例性的，如图7所示，图7展示了在主控对象持有虚拟枪械的情况下，主控对象在地面上的投影701。示例性的，如图8所示，图8展示了在主控对象在切换虚拟枪械的情况下，主控对象在地面上的投影801。从图7和图8可以明显看出，主控对象的投影701和投影801是符合实际情况的，能够良好地还原出主控对象的投影。
在一个具体的实施方式，采用本申请实施例的方法来获取主控对象的投影时，只需要在CPU上消耗0.033ms，而采用相关技术来获取主控对象的投影时，需要在CPU上消耗4.133ms。明显地，本申请实施例的方法可以有效减少计算机设备的计算时间，提高效率。
综上所述，本申请实施例在生成主控对象的投影时，只需要从本体动画蓝图中提取原始骨骼模型，就可以根据原始骨骼模型得到主控对象的投影。该方法不需要额外设置一套动画蓝图就可以得到主控对象的投影，可以简化获取主控对象的投影的流程，不需要过多的计算量就能得到主控对象的投影，降低计算机设备的计算压力，即使计算机设备的计算能力较弱，也能完成主控对象的投影。
图9示出了本申请一个实施例提供的生成主控对象投影的方法的流程示意图。该方法可由图1所示的终端120执行，该方法包括以下步骤：
步骤901：在本体动画蓝图的第一骨骼变形处理前，从本体动画蓝图中提取原始骨骼模型。
第一骨骼变形处理用于缩放主控对象的摄像机模型和原始骨骼模型的重合区域处的骨骼。由于主控对象是以第一人称视角观察虚拟环境的对象，所以需要将摄像机模型安置在主控对象的头部，以实现第一人称视角的效果。但是，又因为主控对象的头部也是存在模型的，这种情况会导致穿模的出现。因此，对主控对象的摄像机模型和原始骨骼模型的重合区域处原始骨骼模型的骨骼进行缩放，使得摄像机模型和原始骨骼模型不存在重合区域，避免穿模情况的出现。
可选地，通过程序设计来实现第一骨骼变形处理。
步骤902：基于主控对象的当前状态，调整原始骨骼模型的姿势，得到投影模型。
示例性的，基于主控对象的当前状态，采用反向动力学调整原始骨骼模型的姿势，得到 投影模型。
可选地，当主控对象的状态发生变化时，基于变化后的状态，调整原始骨骼模型的姿势，得到投影模型。示例性的，主控对象由静止状态变化为跑步状态，则将主控对象由静止姿势变化为跑步姿势。
可选地，基于周期性变化调整原始骨骼模型的姿势。比如，主控对象在步行状态下，双脚交替移动，故基于双脚周期性的交替移动，改变原始骨骼模型的姿势。
步骤903：将投影模型替换为一体化投影模型。
可选地，投影模型包括至少两个组件模型，至少两个组件模型包括主控对象上不同部位的模型。比如，组件模型包括头模型、躯干模型、上肢模型、下肢模型中的至少一种。则在调用每一个组件模型进行渲染时，都会产生一次绘制调用，则总计会产生多次绘制调用。多次绘制调用会对计算机设备的GPU(Graphics Processing Unit，图形处理器)带来较大的渲染压力。示例性的，如图10所示，当组件模型包括头模型、躯干模型、上肢模型和下肢模型时，则需要提交至少四种渲染调用，这极大地增加了GPU的负担。
因此，在本申请实施例中，出于投影的特性，主控对象的投影的本身精度并不高，即使存在一些偏差，也不会影响投影本身的精度。因此，本体模型包括至少两个组件模型，至少两个组件模型包括主控对象上不同部位的模型，将投影模型替换为一体化投影模型，一体化投影模型是合并至少两个组件模型后的低面模型，一体化投影模型的面数小于投影模型的面数。在一种具体的实现方式中，一体化投影模型不包括组件模型，一体化投影模型由一个完整的模型组成。示例性的，如图11所示，图11展示了主控对象的一体化投影模型1101。
即，在渲染本体模型时，需执行对至少两个组件模型的渲染；然而，在渲染主控对象的投影时，只需执行对一体化投影模型的渲染，一体化模型的面数少于本体模型的面数。
示例性的，如图12所示，在将投影模型替换为一体化投影模型后，只需要提交一次渲染就可以得到主控对象的投影，减轻了GPU的负担。
在一些情况下，主控对象持有虚拟物品，同样为了降低GPU的渲染压力，可以将主控对象持有的虚拟物品的模型替换为一体化物品模型。示例性的，若主控对象持有虚拟枪械，则虚拟枪械也包括至少两个物品组件模型(例如，枪托模型、消音器模型、握把模型等)，需要将虚拟枪械的模型替换为一体化枪械模型，以便对枪械投影的渲染，如图13所示，将包括至少两个物品组件模型的枪械模型替换为一体化枪械模型1301。
步骤904：对一体化投影模型进行渲染，得到主控对象的投影。
可选地，主控对象的投影是虚拟环境中背光侧的投影。示例性的，主控对象的投影是虚拟环境中地面上的投影，或者，主控对象的投影是虚拟环境中墙壁上的投影，或者，主控对象的投影是虚拟环境中天花板上的投影。
可选地，主控对象的投影还可以指反射面上的图像。例如，主控对象的投影指镜面上主控对象的图像，又例如，主控对象的投影指水面上主控对象的图像。
综上所述，本申请实施例在生成主控对象的投影时，会在第一骨骼变形处理前，从动画蓝图中提取原始骨骼模型得到主控对象的投影，保证生成的投影是存在头部的。相较于相关技术使用两套不同的动画蓝图来同时获取主控对象的本体和投影，该方法不需要额外设置一套动画蓝图就可以得到主控对象的投影，可以简化获取主控对象的投影的流程，不需要过多的计算量就能得到主控对象的投影，降低计算机设备的计算压力。
而且，将投影模型的替换为一体化投影模型，降低了计算机设备提交渲染的次数，可以减轻GPU的工作压力。
图14示出了本申请一个实施例提供的生成主控对象投影的方法的流程示意图。该方法可由图1所示的终端120执行，该方法包括以下步骤：
步骤1401：在本体动画蓝图的第二骨骼变形处理前，从本体动画蓝图中提取原始骨骼 模型。
第二骨骼变形处理用于在主控对象处于目标当前状态时，扭曲原始骨骼模型。在一个具体的例子中，当主控对象进行左右探身时，会对主控对象的骨骼模型进行过量扭曲，这是为了主控对象在障碍物后能够探身，且探身后能够观察到虚拟环境中的其他对象，因此需要进行第二骨骼变形处理。但是如果在第二骨骼变形处理后提取骨骼模型，由于骨骼模型已经被过量扭曲了，因此最后得到的投影也是处于过量扭曲的状态，如图4所示，主控对象的投影401处于过量扭曲的状态，但是这种过量扭曲的状态并不是正常人类可以实现的。因此，在本申请中，需要在本体动画蓝图的第二骨骼变形处理前，从本体动画蓝图中提取原始骨骼模型。
步骤1402：基于主控对象的当前状态，调整原始骨骼模型的姿势，得到投影模型。
示例性的，基于主控对象的当前状态，采用反向动力学调整原始骨骼模型的姿势，得到投影模型。
可选地，当主控对象的状态发生变化时，基于变化后的状态，调整原始骨骼模型的姿势，得到投影模型。示例性的，主控对象由静止状态变化为跑步状态，则将主控对象由静止姿势变化为跑步姿势。
可选地，基于周期性变化调整原始骨骼模型的姿势。比如，主控对象在步行状态下，双脚交替移动，故基于双脚周期性的交替移动，改变原始骨骼模型的姿势。
步骤1403：将投影模型替换为一体化投影模型。
可选地，投影模型包括至少两个组件模型，至少两个组件模型包括主控对象上不同部位的模型。比如，组件模型包括头模型、躯干模型、上肢模型、下肢模型中的至少一种。
本体模型包括至少两个组件模型，至少两个组件模型包括主控对象上不同部位的模型。一体化投影模型是合并至少两个组件模型后的低面模型，一体化投影模型的面数小于投影模型的面数。在一种具体的实现方式中，一体化投影模型不包括组件模型，一体化投影模型由一个完整的模型组成。示例性的，如图11所示，图11展示了主控对象的一体化投影模型1101。
在一些情况下，主控对象持有虚拟物品，同样为了降低GPU的渲染压力，可以将主控对象持有的虚拟物品的模型替换为一体化物品模型。示例性的，若主控对象持有虚拟枪械，则虚拟枪械也包括至少两个物品组件模型，需要将虚拟枪械的模型替换为一体化枪械模型，以便对枪械投影的渲染，如图13所示，将包括至少两个物品组件模型的枪械模型替换为一体化枪械模型1301。
步骤1404：对一体化投影模型进行渲染，得到主控对象的投影。
可选地，主控对象的投影是虚拟环境中背光侧的投影。示例性的，主控对象的投影是虚拟环境中地面上的投影，或者，主控对象的投影是虚拟环境中墙壁上的投影，或者，主控对象的投影是虚拟环境中天花板上的投影。
可选地，主控对象的投影还可以指反射面上的图像。例如，主控对象的投影指镜面上主控对象的图像，又例如，主控对象的投影指水面上主控对象的图像。
综上所述，本申请实施例在生成主控对象的投影时，会在第二骨骼变形处理前，从动画蓝图中提取原始骨骼模型得到主控对象的投影，保证生成的投影的形状是正确的。相较于相关技术使用两套不同的动画蓝图来同时获取主控对象的本体和投影，该方法不需要额外设置一套动画蓝图就可以得到主控对象的投影，可以简化获取主控对象的投影的流程，不需要过多的计算量就能得到主控对象的投影，降低计算机设备的计算压力。
而且，将投影模型替换为一体化投影模型，降低了计算机设备提交渲染的次数，可以减轻GPU的工作压力。
在接下来的实施例中，对上述步骤902或步骤1402中涉及的调整原始骨骼模型的姿势 的方法进行简要介绍，本申请实施例以反向动力学为例进行说明，需要说明的是，还可以通过其他方法来调整原始骨骼模型的姿势，本申请对此不做具体限定。
图15示出了本申请一个实施例提供的调整原始骨骼模型的姿势的方法的流程示意图。该方法可由图1所示的终端120执行，图15所示的方法用于进一步精细化调整原始骨骼模型，以提高投影模型的精度。以主控对象处于步行状态为例，主控对象的本体模型需实现脚部和腿部的协调联动，而主控对象的投影模型在精度要求不高的情况下，无需区分出脚部和腿部，在精度要求较高的情况下，投影模型需区分出脚部和腿部，并且，在本申请中腿部的移动是依赖于脚部的移动确定的。图15所示的方法包括以下步骤：
步骤1501：基于主控对象的当前状态，确定子骨骼的目标位置。
原始骨骼模型包括子骨骼和与子骨骼对应的父骨骼，子骨骼位于骨骼链的末端。以主控角色是人形角色为例进行说明，子骨骼可以是人形角色的手，父骨骼则是人形角色的手臂。子骨骼可以是人形角色的脚，父骨骼则是人形角色的腿。
可选地，当前状态包括但不限于攻击、释放技能、购买道具、治疗、调整身体姿态、爬行、步行、骑行、飞行、跳跃、驾驶、拾取、射击、投掷、跑步、静止中的至少一种。
目标位置是在当前状态下，子骨骼需要达到的位置。示例性的，主控对象处于步行状态，子骨骼指主控对象的脚部，且主控对象的脚部处于抬起状态，则目标位置是主控对象的脚部的落点。示例性的，主控对象正在楼梯上扶着栏杆步行，子骨骼指主控对象的手部，且主控对象的手部处于抬起状态，则目标位置是主控对象的手部的落点。
步骤1502：根据目标位置，确定子骨骼的位置。
示例性的，确定子骨骼的位置包括以下子步骤：
示意性的，主控对象处于步行状态，步行状态可简单拆分为抬起状态和落下状态，以此时处于抬起状态为例，步骤1502即用于确定落下状态下的脚部(子骨骼)的位置。
1、确定子骨骼的第一端点到子骨骼的末端的第一向量。
子骨骼的第一端点是子骨骼上远离子骨骼的末端的端点。示例性的，如图16所示，第一向量是子骨骼1602的第一端点1603到子骨骼的末端1605所呈的向量。
示意性的，子骨骼为脚部，第一端点为脚部的脚跟，子骨骼的末端为脚部的脚趾，子步骤1即得到了抬起状态下由脚跟指向脚趾的第一向量。
2、确定第一端点到目标位置的第二向量。
示例性的，如图16所示，第二向量是第一端点1603到目标位置1604所呈的向量。
示意性的，第一端点为脚部的脚跟，目标位置为脚趾的目标落点位置，子步骤2即得到了抬起状态下由脚跟指向目标落点位置的第二向量。
3、基于第一向量和第二向量之间的夹角，旋转子骨骼，确定子骨骼的位置。
示例性的，如图16所示，基于第一向量和第二向量之间的夹角，逆时针旋转子骨骼1602，旋转角度与夹角相同，以得到子骨骼1602的位置。
示意性的，第一向量指抬起状态下脚跟指向脚趾的向量，第二向量指抬起状态下脚跟指向目标位置的向量，子步骤3即基于第一向量和第二向量的夹角，旋转脚部(子骨骼)，得到旋转后的脚部，也即得到落下状态下的脚部。
步骤1503：根据目标位置和子骨骼的位置，确定父骨骼的位置。
示例性的，确定父骨骼的位置包括以下子步骤：
1、确定父骨骼的第二端点到子骨骼的末端的第三向量。
父骨骼的第二端点是父骨骼上远离子骨骼的端点。示例性的，如图17所示，第三向量是父骨骼1601的第二端点1606到子骨骼的末端1605所呈的向量。
示意性的，父骨骼为小腿部位，第二端点为膝盖，子骨骼的末端为脚趾，子步骤1即得到了抬起状态下由膝盖指向脚趾(旋转前)的第三向量。
2、确定第二端点到目标位置的第四向量。
示例性的，如图17所示，第四向量是第二端点1606到目标位置1604所呈的向量。
示意性的，目标位置是脚趾的目标落点位置，第二端点是膝盖，子步骤2即得到了由膝盖指向目标落点位置的第四向量。
3、基于第三向量和第四向量之间的夹角，旋转父骨骼，确定父骨骼的位置。
示例性的，如图17所示，基于第三向量和第四向量之间的夹角，逆时针旋转父骨骼1601，旋转角度与夹角相同，以得到父骨骼1601的位置。
示意性的，第三向量指抬起状态下膝盖指向脚趾的向量，第四向量指抬起状态下膝盖指向目标位置的向量，子步骤3即基于第三向量和第四向量的夹角，旋转小腿(父骨骼)，得到旋转后的小腿，也即得到落下状态下的小腿。

步骤1804：基于当前状态，调整骨骼变形后的原始骨骼模型的姿势，得到主控对象的本体模型。
可选地，基于当前状态，采用反向动力学调整骨骼变形后的原始骨骼模型的姿势，得到主控对象的本体模型。

步骤1805：对本体模型进行渲染，得到主控对象的本体。
可选地，本体模型包括至少两个组件模型，至少两个组件模型包括主控对象上不同部位的模型。比如，本体模型中包括的头模型、躯干模型、上肢模型和下肢模型。在渲染本体模型时，需要分别对至少两个组件模型进行渲染，得到至少两个组件模型的渲染结果。合成至少两个组件模型的渲染结果，得到主控对象的本体。示例性的，分别对头模型、躯干模型、上肢模型和下肢模型进行渲染，得到头模型、躯干模型、上肢模型和下肢模型对应的渲染结果，将这四个渲染结果进行合成，得到主控对象的本体。
综上所述，本实施例提供了一种本体动画蓝图的方法，该方法可以得到主控对象的本体。并且，本体动画蓝图中的原始骨骼模型可以用于获取主控对象的投影。

步骤2002：将初始动画姿势代入到主控对象的骨骼模型中，得到骨骼姿势模型。

步骤2003：基于当前状态，调整骨骼姿势模型的姿势，得到原始骨骼模型。
