技术领域
本申请涉及计算机领域，具体而言，涉及一种人物面部模型的编辑方法及装置。
发明背景
目前，在现有的人物面部模型编辑过程中，往往是通过调整控制器中不同的滑块在进度条中的位置来实现的。例如，在编辑人物面部模型中的眼睛部位时，常常需要在与眼睛部位对应的非常长的控制列表中，依次拖动调整不同的滑块在进度条中的位置，从而完成对眼睛部位的全部编辑。这样，玩家不仅要确保光标所选中的是要调整部位对应的滑块，而且同时还要确认编辑过程中面部的实际变化效果。
也就是说，采用现有的面部模型编辑方式，需要不停地在面部和滑块之间进行切换，编辑过程不直观，而且编辑操作繁琐，增加了操作复杂度和开发难度。

在本实施例中，通过根据在终端所显示的人物面部模型中检测到的光标的位置，确定人物面部模型的多个面部部位中的待操作面部部位，并在检测到对待操作面部部位的选中操作后，响应获取到的对待操作面部部位的编辑操作对待操作面部部位进行编辑，以在人物面部模型中显示编辑后的待操作面部部位。也就是说，通过检测光标所在的位置，确定在人物面部模型的多个面部部位中所选中的待操作面部部位，以便于对待操作面部部位直接完成编辑过程，而无需在额外的控制列表中拖动与待操作面部部位对应的滑块，使用户可以对人物面部模型直接进行面部拾取编辑，从而简化了对人物面部模型的编辑操作，进而克服了在人物面部模型与控制列表中的滑块之间的切换所导致的操作复杂度较高的问题。进一步，通过对人物面部模型中的面部部位直接进行编辑操作，使用户可以直观地看到终端显示的编辑操作以及编辑后的待操作面部部位的变化效果，实现所见即所得，从而使编辑操作可以更加贴近用户需求。
在本实施例中，上述光标所在位置可以但不限于用于指示鼠标在屏 幕上显示的对应位置。
在本实施例中，检测到对待操作面部部位的选中操作时，可以包括但不限于：对待操作面部部位进行特殊显示。例如将该面部部位高亮显示、或在该面部部位显示阴影等。
在本实施例中，上述编辑可以包括以下至少之一：对待操作面部部位进行移动；对待操作面部部位进行旋转；对待操作面部部位进行放大；对待操作面部部位进行缩小。
在本实施例中，根据光标所在位置确定多个面部部位中的待操作面部部位包括：

在本实施例中，获取位置上的像素点的颜色值可以包括但不限于：获取蒙板贴图中与位置对应的像素点的颜色值，其中，蒙板贴图贴合在人物面部模型之上，蒙板贴图包括与多个面部部位一一对应的多个蒙板区域，每个蒙板区域对应一个面部部位，其中，上述像素点的颜色值可以包括以下之一：像素点的红色颜色值、像素点的绿色颜色值、像素点的蓝色颜色值。
在本实施例中，贴合在人物面部模型上的蒙板贴图上的每一个蒙板区域分别与人物面部模型上的一个面部部位对应。也就是说，通过光标选中贴合在人物面部模型之上的蒙板贴图上的蒙板区域，就可以选中人物面部模型中对应的面部部位，从而实现对人物面部模型上的面部部位的直接编辑，达到简化编辑操作的目的。
例如，在本实施例中，可以但不限于通过以下代码构建蒙板贴图：
float4maskColor＝tex2D(FacialMaskSampler,param.uv0)；
float maskR＝maskColor.r*255.0f；
float alpha＝0；
if(IsValEqual(SelectedAreaColor,maskR))
{
alpha+＝FacialMaskParams.y；
}
float4finalColor＝float4(0,2,5,alpha*2.5f*maskColor.b)；
其中，maskColor.r用于指示红通道，maskColor.b用于指示蓝通道。
此外，在本实施例中，可以但不限于预先设置蒙板贴图中各个蒙板区域与对应的像素点的颜色值的映射关系。例如，如表1所示的人物面部模型中鼻子具体包括6个部位，对每个部位分别设置一个红色颜色值(以R颜色值表示)，为了避免误差，例如每个数值之间可以但不限于相差最少10个单位。
表1
Figure PCTCN2017076029-appb-000001
也就是说，确定多个面部部位中与颜色值对应的待操作面部部位可以包括但不限于：在获取蒙板贴图中与位置对应的像素点的颜色值后，可以通过查询映射关系获取与该像素点的颜色值对应的蒙板区域，进而 获取与该蒙板区域对应的待操作面部部位。
在本实施例中，可以但不限于使用像素拾取(pixel picking)的面部拾取技术来检测光标在显示的人物面部模型中的位置。其中，Pixel picking是以模型物件为单位的拾取技术，是一种通过检测光标在显示屏幕上选择或点击的某个虚拟物件并与之交互的方法。其中，上述虚拟物件可以但不限于对应人物面部模型中的面部部位。
在本实施例中，对每个虚拟物件(即面部部位)设置一个标识ID，然后将所有可拾取虚拟物件绘制在一个render target上，ID通过常量寄存器传入。最后通过GetRenderTarget()(即Direct3D里的一个函数)来获取当前光标所在位置的部位的ID。
在本实施例中，在检测光标在显示的人物面部模型中的位置之前，还可以包括：显示人物面部模型和生成的蒙板贴图，其中，蒙板贴图被设置为贴合在人物面部模型之上。
其中，获取人物面部模型的过程可以如下：
面部拾取系统实际上是对贴图色彩敏感的一种拾取方法，实现的核心HLSL代码：
result.color0＝tex2D(FacialMaskSampler,param.uv0)；
result.color0.gb＝param.uv0.xy；
floatdepth＝EncodeFloatToRGBA8(param.homoDepth.x/param.homoDepth.y)；
result.color1＝float4(1.0f,1.0f,0,depth)；//magic code marking for facial mask map
通过下面代码获取屏幕显示的人物面部模型：
tex2D(FacialMaskSampler,param.uv0)；
result.color1＝float4(1.0f,1.0f,0,depth)；
给屏幕中每个像素都设置一个验证码，通过该验证码验证是否属于 人物面部模型。只有符合验证码的像素(等于(1.0,1.0,0))，才会用来按照人物面部模型来处理：
EncodingColorData(queryData,maskCode)；
If(maskCode.r＝＝0xff&&
maskCode.g＝＝0xff&&
maskCode.b＝＝0)
{
mDepthSelted＝maskCode.a；
mIsPickingVaild＝true；
}
通过检测光标在屏幕上的位置，和屏幕当前分辨率，计算出用户光标所在位置选择的像素。

maskCode.g＝＝0xff&&
maskCode.b＝＝0)
{
mDepthSelted＝maskCode.a；
mIsPickingVaild＝true；

在本申请实施例中，以应用于游戏人物面部的化妆过程为例。例如， 将游戏人物在UV空间中有效的部分裁切出来，并对裁切后的面部区域应用上述编辑方法，以建立不同的人物面部模型，如对裁切后的眼睛部位设计多种样式的眼妆。这样如图9所示，在构造游戏人物的面部形象时，可以在面部基础贴图(如图9右侧所示)上为各个局部部位区域选择不同的妆容替换，例如，对所提供的可替换资源：眼部部位(图9所示为眉毛)的妆容切图(如图9中间所示)进行选择，假设选择了实线框中所示的妆容，则可以得到最终的游戏人物的面部形象，如图9左侧所示。采用本申请实施例提供的方法，可以使游戏人物的妆容更加多样化，达到丰富游戏人物的角色形象的效果。
获取局部部位区域的切图的具体过程可以如下：
将DiffuseMap、SpecularMap、NormalMap中有效的部分按照2的N次幂的尺寸裁切出来(16*16,32*32，32*64,64*128)，并记录好坐标位置；
注册表配置：
mMakeupID＝"171"(妆容的美术资源ID)
<mTexSizeBias v＝"512"/><mTexSizeBias v＝"128"/>(裁切的贴图尺寸)
<mTexSizeBias v＝"512"<mTexSizeBias v＝"436"(该贴图在原来尺寸贴图中的指标位置)
注册表配置具体可以为：
<mFacialMakeupParts mMakeupID＝“171”mMakeupID＝“EMP_Eyebrow”mSexualType＝“1”mDiffuseFilePath＝“F_Eyebrow_0001_D.dds”mSpecFilePath＝“F_Eyebrow_0001_S.dds”mNormalFilePath＝“F_Eyebrow_0001_N.dds”mIconImage＝“F_Eyebrow_0001”>
<mTexSizeBias IsStaticArray＝“1”ArrayCount＝“4”[XlsProp]＝“0”>
<mTexSizeBias v＝“512”/>
<mTexSizeBias v＝“128”/>
<mTexSizeBias v＝“512”/>
<mTexSizeBias v＝“436”/>
</mTexSizeBias>
</mFacialMakeupParts>
例如，如图10所示，在选择裁切对象为眼部部位(如眉毛)后，对DiffuseMap、SpecularMap、NormalMap中对应的内容进行裁切，将原始尺寸为1024*1024的内容，裁切为裁切尺寸为512*128的内容。
进一步，在经裁切得到各个局部部位区域的不同切图后，构造游戏人物的过程中，可以但不限于通过点击直接选择所需的切图来构造游戏人物面部。如图11所示，对“眼妆”、“唇妆”、“皮肤”等内容的各个切图进行选择替换，以得到所需的面部形象。
现有技术通常采用枯燥且繁杂的滑条方式进行面部编辑，然而，采用本实施例中提供的人物面部的编辑方法，不仅能够满足游戏应用中不同用户的需求，而且在应用运行的过程中，还可以保证用户在运行流畅的情况下，实现多样化的面部编辑，大大降低了系统消耗，且达到了丰富角色形象的目的。
