具体实施方式
为使本公开的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本公开作进一步详细的说明。显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开实施例中，涉及布料仿真，在布料仿真时可以针对布料的渲染网格，采用渲染网格中的数据(如顶点和三角形索引)直接在渲染网格上进行求解，通过对渲染网格中顶点的仿真计算得出渲染位置，以进行后续布料仿真效果制作。
然而，在游戏中针对虚拟模型的布料的渲染网格中顶点数目越多，将会导致求解的计算量越大。布料仿真作为一种计算量极大的物理仿真效果，在布料制作时对于计算效率和仿真效果往往需要相互妥协，特别是针对计算能力相对偏弱的手机端，若直接使用渲染网格进行仿真，较大的计算量会造成游戏卡顿。
而且，在游戏中采用两层渲染网格来进行布料仿真时，按照传统布料仿真制作方法，分别对每一层渲染网格进行仿真计算以制作布料仿真效果，会导致两层渲染网格之间产生穿插，在手机端游戏中进行布料仿真碰撞检测时，也将增加计算量。
应用本公开实施例的方法，通过采用顶点数量小于渲染网格(即显示网格)的仿真网格进行仿真计算，然后根据渲染网格与仿真网格建立的映射信息，可以通过插值映射获取针对渲染网格的渲染位置以进行渲染，降低了布料仿真的计算量，提升了游戏运行的流畅度，且通过插值可以使渲染网格的顶点相对于仿真网格保持固定的距离，避免了双层渲染网格仿真时的穿透。
以下进行详细的说明：
参照图1，示出了本公开一实施例提供的一种渲染处理的方法的步骤流程图，具体可以包括如下步骤：

在渲染的过程中，可以针对待渲染的虚拟模型，获取用于渲染的显示网格和用于仿真模拟的仿真网格，仿真网格的顶点数量小于显示网格的顶点数量。
具体的，在游戏中进行渲染时，可以针对待渲染的游戏中虚拟模型，获取针对该虚拟对象(即虚拟模型)的渲染网格(即显示网格)和模拟网格(即仿真网格)，该渲染网格可以用于渲染得到布料仿真效果，该模拟网格可以用于进行布料仿真计算。
在制作布料仿真时，针对虚拟模型的网格可以为三角网格数据，该三角网格数据可以为多个三角形的集合，其中，每个三角形(三角面片)具有三个顶点，可以将虚拟模型的网格中所有三角形的顶点数目总和作为网格的总顶点数，例如，仿真网格的总顶点数小于显示网格的总顶点数。
步骤102，响应触发所述虚拟模型进行形变的形变事件，根据所述形变事件确定所述仿真网络的顶点位置参数；

针对游戏运行时进行渲染，可以在获取针对虚拟模型的显示网格和仿真网格后，对仿真网格进行仿真处理，进而可以得到仿真处理后仿真网络的顶点位置参数。
步骤103，确定所述显示网格的目标顶点对应的目标映射信息；其中，所述目标映射信息为针对所述仿真网格中目标子网格的目标映射点的信息；
其中，目标顶点可以为显示网格的一个或多个顶点，在游戏中可以针对该顶点进行渲染，目标映射信息可以为针对仿真网格中目标子网格的目标映射点的信息，通过建立显示网格中目标顶点与仿真网格中目标映射点的映射，并可以将映射信息存储于布料资源中，以在游戏中可以获取显示网格的目标顶点对应的映射信息(如映射元组)，该映射建立过程在下文进行详细介绍，在此不作赘述。
作为一示例，目标映射点可以为仿真网格中针对显示网格的目标顶点的映射点；目标子网格可以为仿真网格中针对目标映射点的网格，例如，针对显示网格的顶点P可以在仿真网格的三角形T中具有映射点P’。
在获取显示网格和仿真网格后，可以从游戏的布料资源中，获取针对显示网格的目标顶点对应的目标映射信息，该目标映射信息可以为针对仿真网格中目标子网格的目标映射点的信息。

在确定目标顶点对应的目标映射信息后，由于该目标映射信息中可以具有针对仿真网格中目标子网格的目标映射点的信息，进而可以根据目标映射信息和仿真网格的顶点位置参数，映射得到显示网格中目标顶点对应的目标顶点位置信息。
在游戏的渲染中，可以在仿真网格上进行布料仿真，布料仿真效果可以通过每一帧动画对应的仿真网格中顶点位置的变化而实现，该仿真网格中顶点可以为针对显示网格中顶点的映射点，进而可以由仿真网格中移动后映射点的位置信息，得到显示网格中更新的顶点位置作为渲染位置。

作为一示例，目标重心坐标可以为目标子网格中目标映射点对应的重心坐标，如映射元组中wx,wy,wz。
在确定目标顶点对应的目标映射信息后，可以从目标映射信息中获取针对目标顶点的重心坐标，作为目标重心坐标。
具体的，由于在布料资源中，可以查询显示网格的顶点对应的映射元组，该映射元组中可以具有针对显示网格的顶点P在仿真网格中映射点P’的重心坐标插值wx,wy，进而可以将wx,wy作为目标重心坐标。
子步骤1122，结合所述目标子网格索引、所述目标重心坐标，以及所述仿真网格的顶点位置参数，确定所述目标子网格中目标映射点的目标映射点位置信息。
其中，仿真网格的顶点位置参数可以包括目标子网格的顶点的位置参数，例如，仿真网格中三角形T对应的三个顶点位置。
在得到目标重心坐标后，可以结合目标子网格索引、目标重心坐标，以及仿真网格的顶点位置参数，通过插值计算得到目标子网格中目标映射点的目标映射点位置信息。
例如，可以针对显示网格的顶点P查询得到其映射元组(dist,wx,wy,indexT)，然后可以根据三角形索引indexT确定仿真网格中三角形T，可以获取移动后的三角形T的三个顶点的位置，进而可以通过插值得到仿真网格中针对显示网格顶点P的映射点P’的位置，具体可以采用如下方式进行插值计算：
P’(wx*Ta+wy*Tb+(1-wx-wy)*Tc)
其中，Ta、Tb、Tc可以为仿真网格中移动后的三角形T的三个顶点的位置，wx、wy为显示网格顶点P在仿真网格中映射点P’的重心坐标插值。
在一示例中，可以通过查询目标顶点对应的映射元组，并根据映射元组中三角形索引indexT确定仿真网格中三角形T，进而可以获取三角形T的三个顶点的位置(如Ta，Tb，Tc)，这三个顶点的位置可以为针对仿真网格进行仿真时，仿真网格中三角形T移动后的三个顶点的位置。
子步骤12，从所述目标映射信息中，确定目标距离向量；其中，所述目标距离向量 为所述目标顶点和所述目标映射点之间的距离向量；
作为一示例，目标距离向量可以为目标顶点和目标映射点之间的距离向量，例如，映射元组中dist。
在确定目标顶点对应的目标映射信息后，可以从目标映射信息中获取目标顶点和目标映射点之间的距离向量，作为目标距离向量。
具体的，由于在布料资源中，可以查询显示网格的顶点对应的映射元组，该映射元组中具有顶点P和映射点P’之间的距离向量dist，进而可以将dist作为目标距离向量。
子步骤13，根据所述目标距离向量和所述目标映射点位置信息，确定所述显示网格的目标顶点位置信息。
在具体实现中，可以采用目标距离向量和仿真网格中目标映射点对应的目标映射点位置信息，插值得到显示网格中目标顶点对应的目标顶点位置信息。

其中，目标法向量可以为仿真网格中目标子网格的法向量，例如，仿真网格中三角形对应的三个顶点的法向量。
确定目标顶点对应的目标映射信息后，可以从目标映射信息中获取目标子网格索引，进而可以采用目标子网格索引确定目标子网格，以获取目标子网格的顶点的法向量。
在实际应用中，可以通过查询目标顶点对应的映射元组，并根据映射元组中三角形索引indexT确定仿真网格中三角形T，然后可以获取三角形T的三个顶点的法向量(如Na，Nb，Nc)，该三角形T的法向量可以为三角形T所有相邻三角形的法向量平均值，进而可以插值得到映射点P’的法向量N’，具体可以采用如下方式进行插值计算：

在本公开一实施例中，目标映射信息可以包括目标子网格对应的目标子网格索引，步骤302可以包括如下子步骤：
子步骤21，在所述仿真网格中，确定所述显示网格的目标顶点对应的目标子网格；

具体的，可以对针对显示网格的顶点P，遍历仿真网格上所有三角形，并计算顶点P到各个三角形的空间距离，例如，顶点P与各个三角形的每一个顶点、每一条边、以及三角形平面的距离。
子步骤212，确定最小的距离信息对应的子网格为所述显示网格的目标顶点对应的目标子网格。
在实际应用中，显示网格可以有多个顶点，可以针对每个顶点，遍历仿真网格上所有三角形，并计算顶点到各个三角形的空间距离，进而可以找到针对顶点的最小空间距离的三角形(三角面片)，例如，显示网格的顶点P对应有最小空间距离的三角形T。
子步骤22，确定所述目标子网格对应的目标子网格索引。

在获取显示网格和仿真网格后，可以从仿真网格的多个子网格中，确定显示网格的目标顶点对应的目标子网格，进而可以在目标子网格中，确定目标顶点对应的目标映射点，例如，获取顶点P在仿真网格的三角形T后，可以得到顶点P投影到三角形T所在平面的映射P’。
子步骤32，确定所述目标映射点对应的目标重心坐标。
在确定目标映射点后，可以获取目标映射点相对于目标子网格的顶点的重心坐标，作为目标重心坐标，例如，映射点P’相对于三角形T的三个顶点的重心坐标插值wx，wy，wz，其中，wx+wy+wz＝1.0。
在本公开一实施例中，目标映射信息可以包括目标顶点和目标映射点之间的目标距离向量，步骤302还可以包括如下子步骤：

在实际应用中，可以通过计算得到顶点P与映射点P’的距离dist，dist可以具有符号，用于表示顶点P相当于三角形T平面的方向，例如，顶点P为针对仿真网格的三角形T平面的上层显示网格，或针对仿真网格的三角形T平面的下层显示网格。
在一示例中，针对显示网格的顶点P确定在仿真网格中最近三角形T后，可以得到顶点P投影在三角形T所在平面的映射点P’，然后可以计算出顶点P与映射点P’的距离dist，可以获取P’相对于三角形T的三个顶点的重心坐标插值wx，wy，wz，重心坐标插值三者关系为wx+wy+wz＝1.0，并可以记录下三角形T在仿真网格中的三角形索引indexT，进而可以针对显示网格的顶点P得到映射元组(dist，wx，wy，indexT)，可以将映射元组保存在布料网格资源中。
