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。
在本公开实施例中，在需要对虚拟人体模型进行化妆、对虚拟模型添加水墨风格的纹理等情况下，用户可以期望在上色过程中实时地展现颜色渐变效果。
若在完成单次操作之后在对虚拟模型进行上色，此时单次操作的起点与终点是确定的，那么可以分别确定单次操作的起点颜色与终点颜色，再基于起点颜色与终点颜色确定单次操作中间部分的颜色，以形成颜色渐变效果。
但是，用户往往还期望可以在上色过程中实时地观察到上色效果。由此，本公开实施例实时识别每一时刻下触控操作所处的区域，并将触控在历史触控区域的颜色与所述当前纹理位置的当前颜色进行混合，得到当前纹理位置的目标颜色，从而可以通过虚拟操作实现对虚拟模型的实时上色。
此外，由于虚拟模型通常是凹凸不平的，在虚拟模型上连续的位置变化，可能涉及三维空间中多个方向的位置变化，从而映射至虚拟模型对应的纹理贴图时，可能出现在纹理贴图中位置变化不连续的情况。虚拟模型进行上色的过程中，面对不连续的纹理贴图，无法简单地确定虚拟操作每一时刻移动的偏移量，因此无法基于偏移量确定虚拟模型在上一 时刻所处的区域，并提取得到该区域的颜色。由此，本公开实施例通过对虚拟操作在上一时刻所处区域的纹理贴图颜色提前进行采集，得到记载有该区域颜色的渲染纹理，其后可以基于渲染纹象简便地确定虚拟操作在上一时刻所处区域对应的颜色，从而可以简便地完成颜色混合。
参照图1，示出了本公开实施例中提供的一种数据处理方法的步骤流程图，具体可以包括如下步骤：
步骤101，响应作用于虚拟模型的触控操作，获取在当前第n+1时刻时，所述触控操作在所述虚拟模型的模型网格的当前网格位置，其中，所述n≥1；
在本公开实施例中，虚拟模型可以为三维模型。例如，三维的人体模型、动物模型、植物模型、建筑模型等。
若用户需要对虚拟模型进行上色，可以对所述虚拟模型执行触控操作。每次触控操作可以是连续的、无中断的移动，即每次所述触控操作可以认为是单笔作画，其可以绘制出连续的图案。
在用户进行触控操作的一段时间内，可以实时地获取当前第n+1时刻时，触控操作在虚拟模型的模型网格的当前网格位置，以确定当前需要进行上色的位置。
其中，由于触控操作可以在第一时刻时在虚拟模型上添加预设的颜色，其后从第二时刻开始，随着触控操作的移动，将添加的颜色与虚拟模型纹理所具有的颜色进行混合，以实现上色涂抹的效果。从而n≥1。
具体而言，虚拟模型可以通过一电子设备中的显示屏进行展示。用户可以通过触控显示屏、通过电子设备连接的外设设备如鼠标、触控笔、键盘等发出触控操作。触控操作可以指向显示屏中的某一位置，以指向显示屏中展示的虚拟模型中的某一位置，从而可以确定触控操作在虚拟模型的模型网格的当前网格位置。
在具体实现中，用户的触控操作可以用于控制一笔刷遮罩，笔刷遮罩当前所覆盖的位置，可以认为是触控操作在虚拟模型的模型网格所处的当前网格位置。
步骤102，根据所述当前网格位置确定所述虚拟模型的纹理贴图的当前纹理位置；
在确定触控操作当前所处的当前网格位置之后，可以根据当前网格位置，进一步确定当前网格位置所对应的虚拟模型的纹理贴图的当前纹理位置，以确定纹理贴图中需要进行上色的位置。
在具体实现中，可以预先设置虚拟模型的模型网格在三维空间中的网格位置与纹理贴图的纹理位置之间的对应关系，从而在确定触控操作对应的模型网格的当前网格位置之后，即可以基于预设的对应关系，确定当前网格位置所对应的虚拟模型的纹理贴图的当前纹理位置。
步骤103，采集所述触控操作在第n时刻时对应的渲染纹理，获取所述渲染纹理中所述触控操作在历史触控区域的颜色信息，所述渲染纹理为根据所述触控操作在所述纹理贴图的历史位置处的颜色生成的纹理；
具体而言，为了实现颜色渐变的效果，可以将触控操作在第n时刻所处的历史触控区域的颜色与当前纹理位置的当前颜色进行混合，以使每一时刻确定的目标颜色都是基于历史触控区域的颜色进行变化的，从而可以展现出颜色逐渐变化的效果。
由此，可以提前采集触控操作中第n时刻对应的渲染纹理(Render Texture)，以便在触控操作对应的纹理贴图的位置变化可能不连续的情况下，可以通过提前采集触控操作在所述纹理贴图的历史位置处的颜色生成的纹理，实现记录当前时刻的上一时刻的目标颜色，以便处理颜色的混合。具体地，渲染纹理中记载有历史触控区域的尺寸、维度、颜色等多种信息。从而可以从渲染纹理中获取触控操作在历史触控区域的颜色信息。
步骤104，将所述历史触控区域的颜色与所述当前纹理位置的当前颜色进行混合，得到所述当前纹理位置的目标颜色；
在通过渲染纹理获取得到历史触控区域的颜色之后，可以进一步从纹理贴图中确定当前纹理位置，并提取当前纹理位置的当前颜色。其后，可以将历史触控区域的颜色与当前纹理位置的当前颜色进行混合，确定当前纹理位置的目标颜色。
步骤105，通过所述目标颜色更新所述纹理贴图的所述当前纹理位置处的颜色；
在确定当前纹理位置的所要添加的目标颜色之后，采用目标颜色更新纹理贴图中当前纹理位置处的颜色，从而完成虚拟模型中当前网格位置对应纹理的上色。
由于当前纹理位置的目标颜色是基于第n时刻，即上一时刻触控操作所处的历史触控区域对应纹理颜色以及第n+1时刻，即当前触控区域对应的纹理颜色确定的。由此，目标颜色可以是基于历史触控区域的颜色的基础上，参考当前纹理位置的当前颜色进行变化的，从而可以中基于历史触控区域的颜色进行颜色简便的同时，与虚拟模型的当前颜色较好地进行融合，实现自然的颜色渐变效果。
步骤106，根据更新后的所述纹理贴图渲染所述第n+1时刻的所述虚拟模型。
在更新纹理贴图当前纹理位置处的颜色之后，可以采用更新后的所述纹理贴图渲染所述第n+1时刻的所述虚拟模型，从而可以实现在通过触控操作对虚拟模型进行上色的过程中，实时地展示虚拟模型的上色效果，从而可以实现为用户提供在三维空间中的虚拟模型进行实时上色涂抹的功能。
通过本公开的数据处理方法，响应作用于虚拟模型的触控操作，获取在当前第n+1时刻时，触控操作在虚拟模型的模型网格的当前网格位置，其中，n≥1；根据当前网格位置确定虚拟模型的纹理贴图的当前纹理位置；采集触控操作在第n时刻时对应的渲染纹理，获取渲染纹理中触控操作在历史触控区域的颜色信息，渲染纹理为根据触控操作在纹理贴图的历史位置处的颜色生成的纹理；将历史触控区域的颜色与当前纹理位置的当前颜色进行混合，得到当前纹理位置的目标颜色；通过目标颜色更新纹理贴图的当前纹理位置处的颜色；根据更新后的纹理贴图渲染第n+1时刻的虚拟模型，从而可以实现在三维空间中对虚拟模型进行颜色渐变的上色涂抹效果。
参照图2，示出了本公开实施例中提供的一种数据处理方法的步骤流程图，具体可以 包括如下步骤：
步骤201，响应作用于虚拟模型的触控操作，获取在当前第n+1时刻时，所述触控操作在所述虚拟模型的模型网格的当前网格位置，其中，所述n≥1；
若用户需要对虚拟模型进行上色，可以对所述虚拟模型执行触控操作。每次触控操作可以是连续的、无中断的移动，即每次所述触控操作可以认为是单笔作画，其可以绘制出连续的图案。
在用户进行触控操作的一段时间内，可以实时地获取当前第n+1时刻时，触控操作在虚拟模型的模型网格的当前网格位置，以确定当前需要进行上色的位置。
其中，由于触控操作可以在第一时刻时在虚拟模型上添加预设的颜色，其后从第二时刻开始，随着触控操作的移动，将添加的颜色与虚拟模型纹理所具有的颜色进行混合，以实现上色涂抹的效果。从而n≥1。
具体而言，虚拟模型可以通过一电子设备中的显示屏进行展示。用户可以通过触控显示屏、通过电子设备连接的外设设备如鼠标、触控笔、键盘等发出触控操作。触控操作可以指向显示屏中的某一位置，以指向显示屏中展示的虚拟模型中的某一位置，从而可以确定触控操作在虚拟模型的模型网格的当前网格位置。
在具体实现中，用户的触控操作可以用于控制一笔刷遮罩，笔刷遮罩当前所覆盖的位置，可以认为是触控操作在虚拟模型的模型网格所处的当前网格位置。
在本公开的一种示例中，所述方法还包括：
S11，对于第一时刻，响应作用于虚拟模型的触控操作，获取在第一时刻时，所述触控操作在所述虚拟模型的模型网格的当前网格位置；
为了实现对模型进行上色涂抹的效果，在第一时刻，可以对虚拟模型进行上色，其后随着触控操作在后续时刻的移动，基于第一时刻添加的颜色对虚拟模型其他位置进行上色，从而实现将添加的颜色自然地涂抹至其他区域的效果。
由此，对于第一时刻，可以响应作用于虚拟模型的触控操作，获取在第一时刻时，所述触控操作在所述虚拟模型的模型网格的当前网格位置，以便确定虚拟模型需要进行上色的位置。
S12，根据所述当前网格位置确定所述虚拟模型的纹理贴图的当前纹理位置；
在确定第一时刻下触控操作在虚拟模型的模型网格的当前网格位置之后，为了实现对虚拟模型上色，可以进一步确定虚拟模型的纹理贴图中，当前网格位置所对应的的当前纹理位置。
具体而言，预先设置虚拟模型的模型网格在三维空间中的网格位置与纹理贴图的纹理位置之间的对应关系，从而在确定触控操作对应的模型网格的当前网格位置之后，即可以基于预设的对应关系，确定当前网格位置所对应的虚拟模型的纹理贴图的当前纹理位置。
S13，通过预设的初始颜色更新所述纹理贴图的所述当前纹理位置处的颜色；
在确定纹理贴图的当前纹理位置之后，即可以通过预设的初始颜色更新纹理贴图的当 前纹理位置处的颜色，实现对虚拟模型的上色。其中，预设的初始颜色可以由用户选择确定。
S14，根据更新后的所述纹理贴图渲染所述第一时刻的所述虚拟模型。
完成纹理贴图的更新之后，可以根据更新后的所述纹理贴图渲染第一时刻的所述虚拟模型，从而可以向用户展示实时的颜色展示效果。
步骤202，根据所述当前网格位置确定所述虚拟模型的纹理贴图的当前纹理位置；
在确定触控操作当前所处的当前网格位置之后，可以根据当前网格位置，进一步确定当前网格位置所对应的虚拟模型的纹理贴图的当前纹理位置，以确定纹理贴图中需要进行上色的位置。
在具体实现中，可以预先设置虚拟模型的模型网格在三维空间中的网格位置与纹理贴图的纹理位置之间的对应关系，从而在确定触控操作对应的模型网格的当前网格位置之后，即可以基于预设的对应关系，确定当前网格位置所对应的虚拟模型的纹理贴图的当前纹理位置。
在本公开的一种实施例中，所述根据所述当前网格位置确定所述虚拟模型的纹理贴图的当前纹理位置的步骤，包括：
S21，确定预设的区域遮罩是否与所述当前网格位置存在重叠；
具体而言，所述虚拟模型可能不需要在所有位置皆进行上色，而只需要在部分位置进行上色。例如，在对三维人体模型的面部进行化妆的情况下，若对面颊进行上色，可以不希望将颜色涂抹至面颊以外如鼻子、嘴唇等部位，而只希望在面颊部位进行上色。同时，也不希望其他部位所处位置的颜色对当前上色产生影响。
在此情况下，为了避免无关区域对当前上色涂抹过程产生的不良影响，可以采用预设的区域遮罩，对无关区域进行遮蔽。由此，在确定触控操作在虚拟模型的模型网格的当前网格位置之后，还所需要进一步确定当前网格位置是否与区域遮罩存在重叠，以确定当前网格位置是否包含了不希望进行上色的区域。
S22，若预设的区域遮罩与所述当前网格位置存在重叠，将所述当前网格位置中与所述区域遮罩重叠之外的区域作为目标网格位置；
若区域遮罩与当前网格位置存在重叠，则可以认为当前网格位置包含了不希望进行上色的区域。则此时可以将当前网格位置中未被覆盖的区域作为目标网格位置，以避免对无关区域进行上色。
S23，根据所述目标网格位置确定所述虚拟模型的纹理贴图的当前纹理位置。
在确定目标网格位置之后，可以基于目标网格位置确定虚拟模型的纹理贴图的当前纹理位置，以在纹理贴图中确定所需要进行上色的区域。
作为本公开的一种示例，图3为本公开实施例的一种区域遮罩示意图，若当前网格位置在第n+1帧所处的当前网格位置302被区域遮罩301覆盖，则可以将当前网格位置302中与区域遮罩301重叠之外的区域作为目标网格位置，后续基于目标网格位置进行上色， 避免上色超出允许上色区域。
步骤203，采集所述触控操作在第n时刻时对应的渲染纹理，获取所述渲染纹理中所述触控操作在历史触控区域的颜色信息，所述渲染纹理为根据所述触控操作在所述纹理贴图的历史位置处的颜色生成的纹理；
具体而言，为了实现颜色渐变的效果，可以将触控操作在第n时刻所处的历史触控区域的颜色与当前纹理位置的当前颜色进行混合，以使每一时刻确定的目标颜色都是基于历史触控区域的颜色进行变化的，从而可以展现出颜色逐渐变化的效果。
由此，可以提前采集触控操作中第n时刻对应的渲染纹理(Render Texture)，以便在触控操作对应的纹理贴图的位置变化可能不连续的情况下，可以通过提前采集触控操作在所述纹理贴图的历史位置处的颜色生成的纹理，实现记录当前时刻的上一时刻的目标颜色，以便处理颜色的混合。具体地，渲染纹理中记载有历史触控区域的尺寸、维度、颜色等多种信息。从而可以从渲染纹理中获取触控操作在历史触控区域的颜色信息。
在本公开的一种实施例中，所述采集所述触控操作在第n时刻时对应的渲染纹理的步骤，包括：
S31，采用虚拟摄像机拍摄所述触控操作在第n时刻对应的历史触控区域，得到第n时刻对应的渲染纹理。
具体而言，三维处理软件如unity、houdini等，可以在软件中提供虚拟摄像机功能，其可以允许用户对虚拟模型进行拍摄，得到某一时刻下的渲染纹理(Render Texture)。
由此，可以采用虚拟摄像机拍摄笔刷遮罩在第n时刻对应的历史触控区域，以获得第n时刻对应的渲染纹理，以便在无法简单基于虚拟模型上的网格位置或者纹理贴图上的纹理位置确定触控操作上一帧所处位置的情况下，也可以根据渲染纹理获取得到上一时刻，即第n时刻的颜色信息以进行颜色混合。
在本公开的一种实施例中，所述采集所述触控操作在第n时刻时对应的渲染纹理的步骤，包括：
S41，确定预设的区域遮罩是否与所述触控操作在第n时刻对应的历史触控区域存在重叠；
具体而言，所述虚拟模型可能不需要在所有位置皆进行上色，而只需要在部分位置进行上色。由此，为了避免生成渲染纹理的过程中，由于采集得到与虚拟模型上色无关的位置，从而导致后续可能出现颜色混合效果异常的情况，可以在采集渲染纹理时，确定预设的区域遮罩是否与所述触控操作在第n时刻对应的历史触控区域存在重叠，以确定是否可能采集到无关位置的颜色信息。
S42，若预设的区域遮罩与所述触控操作在第n时刻对应的历史触控区域存在重叠，采集所述历史触控区域与所述区域遮罩重叠之外的区域，得到渲染纹理。
若预设的区域遮罩与所述触控操作在第n时刻对应的历史触控区域存在重叠，则此时为了避免采集到无关位置的颜色信息。可以针对历史触控区域中与所述区域遮罩重叠之外 的区域进行采集，得到渲染纹理，以使颜色可以正常进行混合。
步骤204，确定所述历史触控区域对应的第一混合比例，以及所述当前纹理位置对应的第二混合比例；
在通过渲染纹理获取得到历史触控区域的颜色之后，可以进一步从纹理贴图中确定当前纹理位置，并提取当前纹理位置的当前颜色。其后，可以将历史触控区域的颜色与当前纹理位置的当前颜色进行混合，确定当前纹理位置的目标颜色。
在将历史触控区域的颜色与当前纹理位置对应的当前颜色进行混合的过程中，可以分别确定不同颜色在目标颜色中占据的比例，以确定在当前纹理位置的上色效果。由此，可以分别确定历史触控区域对应的第一混合比例，以及当前纹理位置对应的第二混合比例。其中，第一混合比例与第二配合比例之和可以为100％。
在具体实现中，第一混合比例与第二配合比例的值可以根据实际需要确定。例如，在n+1的数值较小的情况下，为了获得更接近预设的初始颜色的色彩，可以设置第一混合比例较大而第二配合比例较小。而在n+1的数值较大的情况下，为了获得更加接近虚拟模型原有颜色的色彩，可以设置第一混合比例较小而第二配合比例较大。又例如，预设的初始颜色相对于虚拟模型原有颜色较为不明显的情况下，为了突出上色效果，可以设置第一混合比例较大而第二配合比例较小。而在预设的初始颜色相对于虚拟模型原有颜色较为明显的情况下，为了避免添加的颜色与虚拟模型对比过于强烈，可以设置第一混合比例较小而第二配合比例较大。
步骤205，根据所述第一混合比例与所述第二混合比例，将所述历史触控区域的颜色与所述当前纹理位置对应的当前颜色进行混合，得到所述当前纹理位置的目标颜色；
在确定第一混合比例与第二混合比例之后，可以根据所述第一混合比例与所述第二混合比例，将历史触控区域的颜色与所述当前纹理位置对应的当前颜色进行混合，得到当前纹理位置的目标颜色，以确定当前纹理位置所要展示的颜色效果。
在具体实现中，目标颜色可以采用如下公式计算得到：
目标颜色＝历史笔刷区域的颜色×第一混合比例+当前笔刷区域的颜色×第二混合比例。
步骤206，通过所述目标颜色更新所述纹理贴图的所述当前纹理位置处的颜色；
在确定当前纹理位置的所要添加的目标颜色之后，采用目标颜色更新纹理贴图中当前纹理位置处的颜色，从而完成虚拟模型中当前网格位置对应纹理的上色。
由于当前纹理位置的目标颜色是基于第n时刻，即上一时刻触控操作所处的历史触控区域对应纹理颜色以及第n+1时刻，即当前触控区域对应的纹理颜色确定的。由此，目标颜色可以是基于历史触控区域的颜色的基础上，参考当前纹理位置的当前颜色进行变化的，从而可以中基于历史触控区域的颜色进行颜色简便的同时，与虚拟模型的当前颜色较好地进行融合，实现自然的颜色渐变效果。
步骤207，根据更新后的所述纹理贴图渲染所述第n+1时刻的所述虚拟模型。
在更新纹理贴图当前纹理位置处的颜色之后，可以采用更新后的所述纹理贴图渲染所述第n+1时刻的所述虚拟模型，从而可以实现在通过触控操作对虚拟模型进行上色的过程中，实时地展示虚拟模型的上色效果，从而可以实现为用户提供在三维空间中的虚拟模型进行实时上色涂抹的功能。
作为本公开的一种具体示例，图4为本公开实施例中提供的一种虚拟模型上色示意图。
如图4(a)所示，对于第一时刻，可以响应作用于虚拟模型的触控操作，获取在第一时刻时，所述触控操作在所述虚拟模型的模型网格的当前网格位置，以便确定虚拟模型需要进行上色的位置，其后根据所述当前网格位置确定所述虚拟模型的纹理贴图的当前纹理位置，通过预设的初始颜色更新所述纹理贴图的所述当前纹理位置处的颜色，实现对虚拟模型初次上色。根据更新后的所述纹理贴图渲染所述第一时刻的所述虚拟模型之后，可以采用虚拟摄像机拍摄所述触控操作在第一时刻对应的历史触控区域，得到第一时刻对应的渲染纹理。
如图4(b)所示，对于第二时刻，可以确定响应作用于虚拟模型的触控操作，获取在当前第二时刻时，所述触控操作在所述虚拟模型的模型网格的当前网格位置。根据所述当前网格位置确定所述虚拟模型的纹理贴图的当前纹理位置之后，可以采集所述触控操作在第一时刻时对应的渲染纹理，以获取渲染纹理中触控操作在历史触控区域的颜色信息。将所述历史触控区域的颜色与所述当前纹理位置的当前颜色进行混合，得到所述当前纹理位置的目标颜色之后，通过所述目标颜色更新所述纹理贴图的所述当前纹理位置处的颜色，并根据更新后的所述纹理贴图渲染所述第二时刻的所述虚拟模型，从而可以实时地在模型中展示上色效果。上色效果如图4(c)所示。其后可以再采用虚拟摄像机拍摄所述触控操作在第二时刻对应的历史触控区域，得到第二时刻对应的渲染纹理。
如图4(d)所示，对于第三时刻，可以确定响应作用于虚拟模型的触控操作，获取在当前第三时刻时，所述触控操作在所述虚拟模型的模型网格的当前网格位置。根据所述当前网格位置确定所述虚拟模型的纹理贴图的当前纹理位置之后，可以采集所述触控操作在第二时刻时对应的渲染纹理，以获取渲染纹理中触控操作在历史触控区域的颜色信息。将所述历史触控区域的颜色与所述当前纹理位置的当前颜色进行混合，得到所述当前纹理位置的目标颜色之后，通过所述目标颜色更新所述纹理贴图的所述当前纹理位置处的颜色，并根据更新后的所述纹理贴图渲染所述第三时刻的所述虚拟模型，从而可以实时地在模型中展示上色效果。上色效果如图4(e)所示。由此可以实现在虚拟模型上进行颜色渐变的上色效果。
