优先权信息

技术领域
本公开涉及场景渲染技术领域，尤其涉及一种对象渲染方法、装置、电子设备、存储介质及程序产品。
背景技术
由于人眼的构造导致人眼注视区域的清晰度最高，而越往注释区域外围的区域的清晰度越来越低，而注视点渲染(Foveated Render，FR)是利用人眼这一特点，对人眼注视区域进行高分辨率渲染，对注视区域以外的区域进行低分辨率渲染，以达到提高渲染速度，节约图形处理器(graphics processing unit，GPU)算力的目的。
然而，FR的优点是使用相对简单，但简单意味着粗暴，通常情况下经过FR后的画面中同一对象会出现不同的分辨率，比如一面墙在靠近显示边界附近是模糊的，而在中心部分是十分清晰的。如此，经过FR会给用户一种对象被撕裂的违和感，使得用户体验较差。

下面结合附图，通过具体的实施例及其应用场景对本公开实施例提供的对象渲染方法进行详细地说明。
如图1所示，本公开实施例提供一种对象渲染方法，该方法可以包括下述的步骤101至步骤102。
101、获取待渲染场景中的目标对象在屏幕中的第一位置信息。
其中，第一位置信息用于指示目标对象的位置，可选地，第一位置信息可以用于指示以下任一项：目标对象的中心点所在的位置，目标对象的轮廓位置。第一位置信息还可以用于指示目标对象上的其他位置，本公开实施例不做限定。
102、在第一位置信息指示该目标对象与用户注视区域的交集满足预设条件的情况下，基于第一渲染策略对该目标对象进行渲染。
其中，第一渲染策略为P×Q个像素点执行一次渲染的策略，P、Q均为正整数。
需要说明的是，本公开实施例中，P×Q个像素点是指一个P行Q列的像素区域，P×Q个像素点也可以指示渲染之后的对象的分辨率，P×Q越大，渲染之后的对象的分辨率越小，P×Q越小，渲染之后的对象的分辨率越大。
其中，P×Q可以为1×1、1×2、2×1、2×2、1×3、3×1、2×3、3×3、1×4、4×1、2×4、4×2、3×4、4×3、4×4、5×5、6×6、8×8等，具体可以根据实际情况确定，本公开实施例不做限定。
其中，本公开实施例中，渲染策略可以为VRS，也可以为其他可以提高渲染速度的渲染策略，具体可以根据实际情况确定，本公开实施例不做限定。
可选地，用户注视区域可以为通过眼球追踪方法确定的，例如通过眼球追踪方法确定用户注视点，并以用户注视点为圆心，第一长度为半径确定注视区域。其中，眼球追踪方法可以根据实际情况确定，此处不做限定。
可选地，用户注视区域可以为预设的区域，即用户注视区域为屏幕上的固定区域。
可选地，第一位置信息用于指示目标对象的中心点所在的位置，上述步骤101可以为先获取目标对象的轮廓信息，然后根据目标对象的轮廓信息，确定目标对象的中心点所在的第一位置信息。其中，获取目标对象的轮廓信息的方法可以参考相关技术，此处不做限定。
可选地，第一位置信息用于指示目标对象的中心点所在的位置，上述步骤101也可以为通过包围盒判断的方法，获取目标对象的中心点所在的第一位置信息。其中，包围盒的形状可以根据实际使用需求确定，此处不做限定。
例如，包围盒为立方体，则可以通过包围盒判断的方法获取目标对象的轮廓上的至少8个点，然后可以通过该至少8个点确定中心点所在的位置(坐标)，以得到第一位置信息。
可以理解，若第一位置信息用于指示目标对象的中心点所在的位置，则预设条件可以为目标对象的中心点位于用户注视区域。
可选地，第一位置信息用于指示目标对象的轮廓位置，即第一信息为目标对象的轮廓信息，上述步骤101可以为获取目标对象的轮廓信息。
可以理解，若第一位置信息用于指示目标对象的轮廓位置，则预设条件可以为目标对象与用户注视区域的交集在目标对象中的占比大于或等于预设比例阈值。其中，预设比例阈值可以为0，可以为小于1的任意值具体预设比例阈值可以根据实际情况确定，此处不做限定。
本公开实施例中，通过获取待渲染场景中的目标对象在屏幕中的第一位置信息；在第一位置信息指示该目标对象与用户注视区域的交集满足预设条件的情况下，基于第一渲染策略对该目标对象进行渲染，可以实现对与用户注视区域的交集满足预设条件的目标对象执行相同的渲染策略，从而可以避免因为了提高渲染效率对待渲染场景进行优化渲染，导致渲染后的目标对象出现被撕裂的违和感，可以提高用户体验。
可选地，本公开实施例提供的对象渲染方法还可以包括下述步骤103。
103、在第一位置信息指示该目标对象与用户注视区域的交集不满足预设条件的情况下，基于第四渲染策略对该目标对象进行渲染。
其中，第四渲染策略可以包括至少一种渲染策略，通过第四渲染策略中的任一种渲染策略渲染的目标对象的分辨率，低于通过第一渲染策略渲染的目标对象的分辨率。，第四渲染策略可以为在步骤101之前通过对待渲染场景进行分析确定的渲染策略，也可以为预设的渲染策略，也可以为待渲染场景之前的默认的渲染策略，具体可以根据实际情况确定，此处不做限定。
可选地，结合图1，如图2所示，上述步骤102具体可以通过下述步骤102a至步骤102b实现。
102a、在第一位置信息指示该目标对象与用户注视区域的交集满足该预设条件的情况下，获取该目标对象的第一信息。
可选地，第一信息包括以下至少一项：目标对象渲染后的第一深度值，所述目标对象的第一尺寸值，贴图区域的梯度信息，目标对象的类型，目标对象的三角面数量。第一信息还可以包括其他信息，具体可以根据实际情况确定，此处不做限定。
其中，该贴图区域为该目标对象在该待渲染场景对应的贴图中的区域。
102b、在第一信息满足目标条件的情况下，基于第一渲染策略对该目标对象进行渲染。
本公开实施例中，可以根据第一信息是否满足目标条件更好地确定是否基于第一渲染策略对该目标对象进行渲染。
可选地，在第一信息包括该目标对象渲染后的第一深度值的情况下，该目标条件包括第一深度值小于或等于预设深度阈值。
其中，对第一深度值的描述可以参考下述步骤201d中对每个对象渲染后的深度信息的相关描述，此处不做限定。预设深度阈值可以根据实际情况确定，此处不做限定。
本公开实施例中，由于深度值较大的对象，最终在屏幕上的显示尺寸较小，通常不是用户关注的对象，无需高清显示，因此，若第一深度值较大，即使渲染后的目标对象的分辨率较低或存在多种分辨率等，也不会影响用户体验，因此可以实现对目标对象的灵活渲染。
可选地，在第一信息包括该目标对象的第一尺寸值的情况下，该目标条件包括第一尺寸值大于或等于预设尺寸阈值。
其中，预设尺寸阈值可以根据实际情况确定，此处不做限定。
其中，第一尺寸值用于指示目标对象投影到屏幕后大概会占用的屏幕区域的尺寸，可以通过包围盒判断的方法获取第一尺寸值；也可以先确定目标对象的轮廓信息，根据目标对象的轮廓信息获取第一尺寸值；还可以通过其他方法获取第一尺寸值，具体可以根据实际情况确定，此处不做限定。
本公开实施例，因为若对象的尺寸较小，通常也不是用户关注的物体，无需高清显示，因此，若第一尺寸值较小，即使渲染后的目标对象的分辨率较低或存在多种分辨率等，也不会影响用户体验，因此可以实现对目标对象的灵活渲染。
可选地，在第一信息包括贴图区域的梯度信息的情况下，该目标条件包括该贴图区域的梯度信息大于或等于预设梯度阈值，该贴图区域为该目标对象在该待渲染场景对应的贴图中的区域。
其中，对贴图区域的梯度信息的描述可以参考下述步骤201b中对贴图的梯度信息的相关描述，此处不做限定。
其中，预设梯度阈值可以根据实际情况确定，此处不做限定。
本公开实施例，因为若对象的梯度信息较小，说明对象的内容变化较平缓，通常也不是用户关注的物体，无需高清显示，因此，若贴图区域的梯度信息较小，即使渲染后的目标对象的分辨率较低或存在多种分辨率等，也不会影响用户体验，因此可以实现对目标对象的灵活渲染。
可选地，在第一信息包括该目标对象的类型的情况下，该目标条件包括该目标对象的类型为预设类型。
其中，对象的类型可以包括人物类、动物类、植物类、建筑物类等，具体可以根据实际情况确定，此处不做限定。预设类型也可以根据实际情况确定，此处不做限定。
本公开实施例中，预设类型为用户关注的类型，需要高清显示，非用户关注类型的对象无需高清显示，因此，若目标对象的类型不是预设类型，即使渲染后的目标对象的分辨率较低或存在多种分辨率等，也不会影响用户体验，因此可以实现对目标对象的灵活渲染。
可选地，在第一信息包括该目标对象的三角面数量的情况下，该目标条件包括该目标对象的三角面数量大于或等于预设数量阈值。
其中，预设数量阈值可以根据实际情况确定，此处不做限定。
其中，对目标对象的三角面数量的描述可以参考下述步骤201b中对每个对象的三角面数量的相关描述，此处不做限定。
本公开实施例中，对象的三角面数量较少时，通常也不是用户关注的物体，无需高清显示，因此，若目标对象的三角面数量较少，即使渲染后的目标对象的分辨率较低或存在多种分辨率等，也不会影响用户体验，因此可以实现对目标对象的灵活渲染。
本公开实施例中，可以通过设定多种第一信息，从而使得对目标对象的渲染更合理。
可以理解，结合上述步骤102a至步骤102b，在上述步骤102之后，本公开实施例提供的对象渲染方法还可以包括下述步骤104。
104、在第一位置信息指示该目标对象与用户注视区域的交集满足预设条件，但第一信息不满足目标条件的情况下，基于第四渲染策略对该目标对象进行渲染。
其中，对第四渲染策略的描述可以参考上述对步骤103中的第四渲染策略的相关描述，此处不再赘述。
可选地，在上述步骤102之前，本公开实施例提供的对象渲染方法还可以包括下述步骤105。
105、确定对该目标对象设定的渲染策略包括第一渲染策略和第二渲染策略。
其中，第二渲染策略为S×T个像素点执行一次渲染的策略，P×Q小于S×T，S、T均为正整数。
其中，对S×T的描述可以参考上述步骤102中对P×Q的相关描述，此处不再赘述。
可选地，第一渲染策略和第二渲染策略可以为依据背景技术涉及的方法设置的渲染策略。
其中，对该目标对象设定的渲染策略除了包括第一渲染策略和第二渲染策略，还可以包括其他渲染策略，此处不做限定。
可以理解，若按照第一渲染策略和第二渲染策略对目标对象进行渲染，则渲染后的目标对象会出现撕裂的违和感。因此，本公开实施例可以避免渲染后的目标对象出现撕裂的违和感，可以提高用户体验。
可选地，结合图1，如图3所示，上述步骤102具体可以通过下述步骤102c和102d实现。
102c、在第一位置信息指示该目标对象与用户注视区域的交集满足该预设条件，且P×Q小于或等于N×M的情况下，将目标对象的渲染策略由第三渲染策略修改为第一渲染策略。
102d、基于第一渲染策略对该目标对象进行渲染。
可选地，本公开实施例提供的对象渲染方法还可以包括在P×Q大于N×M的情况下，基于第三渲染策略对该目标对象进行渲染。
其中，对N×M的描述可以参考上述步骤102中对P×Q的相关描述，此处不再赘述。
可以理解，第三渲染策略为在步骤101之前为目标对象设定的渲染策略，若P×Q小于或等于N×M，则通过第一渲染策略对第一对象进行渲染之后可以使得目标对象的分辨率更高，从而提高用户体验；若P×Q大于N×M，则通过第三渲染策略对第一对象进行渲染之后可以使得目标对象的分辨率更高，从而提高用户体验。
可选地，结合图3，如图4所示，在上述步骤101之前，本公开实施例提供的对象渲染方法还可以包括下述步骤201至步骤202。
201、获取待渲染场景的相关信息。
本公开实施例中，相关信息可以为待渲染场景中的对象的信息，也可以为待渲染场景的贴图的信息，具体可以根据实际情况确定，此处不做限定。
202、根据该相关信息，确定对该待渲染场景进行渲染时采用的渲染策略。
其中，该渲染策略包括对该待渲染场景中的至少一个对象采用N×M个像素点执行一次渲染的策略(即第三渲染策略，此时，第三渲染策略是根据待渲染场景的相关信息确定的)，该至少一个对象包括该目标对象(即根据待渲染场景的相关信息确定在对待渲染场景进行渲染时对目标对象采用第三渲染策略)。
可以理解，可以根据相关信息，确定对该待渲染场景进行渲染时，对整个待渲染场景中的全部对象采用N×M个像素点执行一次渲染的策略，也可以对待渲染场景中的部分对象采用N×M个像素点执行一次渲染的策略，也可以对待渲染场景中的不同对象采用不同数量的像素点执行一次渲染的策略(即部分对象采用N1×M1个像素点执行一次渲染的策略，部分对象采用N2×M2个像素点执行一次渲染的策略，其中，N1、N2不同，M1、M2不同)，具体可以根据实际使用情况确定，本公开实施例不做限定。
需要说明的是，本公开实施例中，可以在对待渲染场景进行渲染之前，确定对待渲染场景的渲染策略，因此本公开实施例上述步骤201至步骤202的过程可以在应用程序的加载阶段实施，从而可以简化在渲染过程中对待渲染场景的渲染策略的判断过程，进而不会和渲染任务抢占设备中的计算资源，如此，可以提高渲染速度。
本公开实施例中，可以根据待渲染场景的相关信息，灵活确定是否对待渲染场景中的至少一个对象采用至少一个像素执行一次渲染的策略，从而可以根据待渲染场景的实际情况，灵活实现提高渲染速度的目的，进而节省图形处理器的算力，降低图形处理器的负载压力。
可选地，该相关信息包括该待渲染场景的贴图的特征信息；其中，该特征信息包括以下至少一项：该贴图的梯度信息，该贴图的内容信息。
示例性地，上述步骤201具体可以通过下述步骤201a至步骤201b实现。
201a、获取该待渲染场景的贴图。
贴图是3D影视动画以及游戏制作过程中的一个环节，即：用图像处理软件(Adobe Photoshop，PS)等平面软件制作材质平面图，覆于利用玛雅(Maya)、3DMax等3D制作软件建立的立体模型上的过程，称为贴图。
其中，贴图可以反映待渲染场景中的对象的表面反射和表面颜色，例如当待渲染场景为游戏场景时，贴图可以反映游戏场景中对象表面的反射和表面颜色。
本公开实施例中，可以在系统层通过钩子(hook)的方法获取待渲染场景的贴图。
hook的方法可以是调用已有的hook方式的代码(hook工具)，也可以是修改相关代码获得的hook方式的代码，具体可以根据实际情况确定，本公开实施例不做限定。
示例性地，在系统层通过hook接入到OpenGL ES(OpenGL for Embedded Systems)的加载(load)贴图的函数中,则可以获取应用程序给OpenGL ES的所有贴图。
示例性地，当应用程序通过调用系统接口将应用程序APK里面保存的待渲染场景的贴图送到图形处理器的过程中，在系统层通过hook的方法获取待渲染场景的贴图。
本公开实施例中，利用hook的思想，对应用程序进行了透明的优化，使得应用程序设计者可以在不改变应用程序已有的功能的同时，为应用程序增加新的功能。
201b、将该贴图的特征信息确定为该相关信息。
可选地，该特征信息包括该贴图的梯度信息，可以通过将贴图输入预先训练好的机器学习梯度模型中，输出贴图的梯度信息，也可以通过数字图像处理方法直接计算贴图的x方向的灰度的梯度信息和y方向的灰度的梯度信息，然后得到该贴图的梯度信息。
可选地，贴图的x方向的灰度的梯度信息可以为每一行中的连续像素点的灰度值的差值的绝对值之和，y方向的灰度的梯度信息可以为每一列中的连续像素点的灰度值的差值的绝对值之和，贴图的x方向的灰度的梯度信息和y方向的灰度的梯度信息还可以通过其他算法计算，具体可以根据实际情况确定，此处不做限定。贴图的梯度信息可以为x方向的灰度的梯度信息和y方向的灰度的梯度信息之和，也可以为x方向的灰度的梯度信息与y方向的灰度的梯度信息的平方和的算术平方根，贴图的梯度信息还可以通过其他的公式计算，具体可以根据实际情况确定，此处不做限定。
其中，机器学习梯度模型可以是基于梯度样本数据对机器学习模型进行训练得到的，机器学习模型可以为基于任意机器学习算法建立的基础模型，梯度样本数据包括大量的梯度样本，每个梯度样本包括贴图和贴图对应的梯度。机器学习梯度模型具体的训练过程可以参考现有相关技术，此处不做限定。
本公开实施例中，结合机器学习梯度模型，在不干扰渲染流程的前提下，最大的发挥图形处理器的能力，挤出更多算力。
其中，该贴图的梯度信息用于表征该贴图的梯度变化情况。通常情况下，贴图的梯度信息越小，说明贴图的梯度变化越平缓，贴图的梯度信息越大，说明贴图的梯度变化越剧烈。当贴图的颜色变化不明显时，贴图的梯度信息较小，当贴图的内容变化不明显时，贴图的梯度信息较小。当贴图的梯度信息较小时，可以对贴图对应的待渲染场景中的至少一个对象采用多像素点执行一次渲染的策略(即渲染策略)，以提高渲染速度，节约图形处理器的算力，降低图形处理器的工作负载。
可选地，该特征信息包括该贴图的梯度信息；上述步骤202具体可以通过下述步骤202a实现。
202a、在该贴图的梯度信息在目标梯度范围的情况下，确定对该待渲染场景进行渲染时采用该目标梯度范围对应的渲染策略。
其中，目标梯度范围可以根据实际使用需求确定，目标梯度范围对应的渲染策略可以根据实际情况确定，本公开实施例不做限定。
可以理解，可以设定多个梯度范围(目标梯度范围为该多个梯度范围中的任一个)，不同的梯度范围对应不同的渲染策略，不同的渲染策略对应不同的N×M。
示例性地，若该多个梯度范围为第一梯度范围、第二梯度范围和第三梯度范围，其中，第一梯度范围中的任意一个梯度信息小于第二梯度范围中的任意一个梯度信息，第二梯度范围中的任意一个梯度信息小于第三梯度范围中的任意一个梯度信息，第一梯度范围对应的N×M为4×4，第二梯度范围对应的N×M为2×2，第三梯度范围对应的N×M为1×1。若贴图的梯度信息在第一梯度范围内，则确定对该待渲染场景进行渲染时采用4×4个像素点执行一次渲染的策略，若贴图的梯度信息在第二梯度范围内，则确定对该待渲染场景进行渲染时采用2×2个像素点执行一次渲染的策略，若贴图的梯度信息在第三梯度范围内，则确定对该待渲染场景进行渲染时采用1×1个像素点执行一次渲染的策略。
本公开实施例中，根据待渲染场景的贴图的梯度信息，确定对待渲染场景进行渲染时采用的渲染策略，可以灵活确定是否对待渲染场景执行多个像素点执行一次渲染的策略。
可选地，该特征信息可以为贴图的内容信息，可以将贴图输入预先训练好的机器学习识别模型中，输出从贴图中识别出的内容信息，也可以通过对象识别算法来识别贴图中的内容信息，然后根据识别出的内容信息，确定对待渲染场景进行渲染时采用的渲染策略。
其中，机器学习识别模型可以是基于识别样本数据对机器学习模型进行训练得到的，机器学习模型可以为基于任意机器学习算法建立的基础模型，识别样本数据包括大量的识别样本，每个识别样本包括贴图和贴图对应的内容信息。机器学习识别模型具体的训练过程可以参考现有相关技术，此处不做限定。
本公开实施例中，结合机器学习识别模型，在不干扰渲染流程的前提下，最大的发挥图形处理器的能力，挤出更多算力。
其中，对象识别算法可以根据实际情况确定，本公开实施例不做限定。
可选地，该特征信息包括该贴图的内容信息；上述步骤202具体可以通过下述步骤202b或步骤202c实现。
202b、在该贴图的内容信息指示该贴图为目标内容的情况下，该目标内容对应的渲染策略。
可选地，目标内容为至少一个预设内容中的任一个。可以设置不同的预设内容对应不同的渲染策略，不同的渲染策略对应不同的N×M；也可以设置不同的预设内容对应相同的渲染策略；具体可以根据实际情况确定，此处不做限定。
可以理解，在该贴图的内容信息指示该贴图为目标内容的情况下，确定对该待渲染场景进行渲染时，对目标内容采用目标内容对应的渲染策略，对该除至少一个预设内容之外的内容采用其他的渲染策略。
可选地，每个预设内容可以为草地、树叶、石头等其他不被关注的内容，具体可以根据实际情况确定，本公开实施例不做限定。每个预设内容对应的渲染策略可以为除1×1个像素点执行一次渲染的策略之外的渲染策略(即目标内容对应的渲染策略的M×N不是1×1)。如此，可以在对待渲染场景进行渲染时，对不被关注的目标内容采用渲染优化策略(即多像素点执行一次渲染的策略)，以提高渲染速度，节约图形处理器的算力，降低图形处理器的工作负载。
可以理解，若该贴图的内容信息指示该贴图为目标内容(目标内容为至少一个预设内容中的任一个)时，确定对该待渲染场景进行渲染时采用该目标内容对应的渲染策略，若该贴图的内容信息指示该贴图不为该至少一个预设内容中的任一个时，确定对该待渲染场景进行渲染时采用1×1个像素点执行一次渲染的策略。
示例性地，设置不同的预设内容对应不同的渲染策略，第一预设内容为草地，草地对应的N×M为4×4，第二预设内容为石头，石头对应的N×M为2×4，在贴图的内容信息指示是除第一目标内容和第二目标内容之外的内容时，N×M为1×1。也就是说，若该贴图的内容信息指示该贴图为草地，则确定对该待渲染场景进行渲染时采用4×4个像素点执行一次渲染的策略，若该贴图的内容信息指示该贴图为石头，则确定对该待渲染场景进行渲染时采用2×4个像素点执行一次渲染的策略，若该贴图的内容信息指示该贴图不是草地，也不是石头，则确定对该待渲染场景进行渲染时采用1×1个像素点执行一次渲染的策略。
可选地，每个预设内容可以为包括人物、动物等其他被关注对象的内容，具体可以根据实际情况确定，本公开实施例不做限定。每个预设内容对应的渲染策略可以为1×1个像素点执行一次渲染的策略(即目标内容对应的渲染策略的M×N是1×1)。如此可以在对待渲染场景进行渲染时，对被关注的目标内容采用1×1个像素点执行一次渲染的策略，如此不会降低被关注内容的分辨率，可以提高用户体验。
可以理解，若该贴图的内容信息指示该贴图为目标内容(目标内容为至少一个预设内容中的任一个)时，确定对该待渲染场景进行渲染时采用1×1个像素点执行一次渲染的策略，若该贴图的内容信息指示该贴图不为该至少一个预设内容中的任一个时，确定对该待渲染场景进行渲染时采用除1×1个像素点执行一次渲染的策略之外的渲染策略(例如2×2个像素点执行一次渲染的策略)。
示例性地，设置每个预设内容对应的渲染策略的N×M为1×1，除至少一个预设内容之外的内容对应的渲染策略的N×M为4×4。也就是说，若该贴图的内容信息指示该贴图为的目标内容(目标内容为该至少一个预设内容中的任一个)，则确定对该待渲染场景进行渲染时采用1×1个像素点执行一次渲染的策略，若该贴图的内容信息指示该贴图不为任一个预设内容，则确定对该待渲染场景进行渲染时采用4×4个像素点执行一次渲染的策略。
本公开实施例中，该贴图的内容信息指示该贴图为目标内容，是从贴图的整体的角度考虑的，当贴图的整体为目标内容时，确定对该待渲染场景进行渲染时采用该目标内容对应的渲染策略，当贴图的整体不为任一预设内容(至少一个预设内容中的任一个)时，确定对该待渲染场景进行渲染时采用其他渲染策略，如此可以灵活确定对该待渲染场景进行渲染时采用的渲染策略，进而当对该待渲染场景进行渲染时采用多像素执行一次渲染的策略，可以提高渲染速度。
202c、在该贴图的内容信息指示该贴图包括预设对象的情况下，确定对该待渲染场景进行渲染时对该预设对象采用该预设对象对应的渲染策略。
可选地，预设对象为至少一个预设对象中的任一个，可以设置不同的预设对象对应不同的渲染策略，不同的渲染策略对应不同的N×M；也可以设置不同的预设对象对应相同的渲染策略；具体可以根据实 际情况确定，此处不做限定。
可选地，每个预设对象可以为草地、石头、大树等不被关注的对象，具体可以根据实际情况确定，本公开实施例不做限定。每个预设对象对应的渲染策略可以为除1×1个像素点执行一次渲染的策略之外的渲染策略(即预设对象对应的渲染策略的M×N不是1×1)，如此，可以在对待渲染场景进行渲染时，对不被关注的预设对象采用渲染优化策略(即多像素点执行一次渲染的策略)，以提高渲染速度，节约图形处理器的算力，降低图形处理器的工作负载。
可以理解，若该贴图的内容信息指示该贴图包括预设对象，确定对该待渲染场景进行渲染时，对该预设对象采用该预设对象对应的渲染策略，对除该至少一个预设对象之外的对象采用1×1个像素点执行一次渲染的策略。
示例性地，设置不同的预设对象对应不同的渲染策略，第一预设对象为草地，草地对应的N×M为4×4，第二预设对象为石头，石头对应的N×M为2×4。也就是说，若该贴图的内容信息指示该贴图包括草地和石头，则确定对该待渲染场景进行渲染时，对草地采用4×4个像素点执行一次渲染的策略，对石头采用2×4个像素点执行一次渲染的策略，对草地和石头之外的对象采用1×1个像素点执行一次渲染的策略。
可选地，每个预设对象也可以为人物、动物等被关注的对象，具体可以根据实际情况确定，本公开实施例不做限定。每个预设对象对应的渲染策略可以为1×1个像素点执行一次渲染的策略(即预设对象对应的渲染策略的M×N是1×1)，如此可以在对待渲染场景进行渲染时，对被关注的预设对象采用1×1个像素点执行一次渲染的策略，如此不会降低被关注对象的分辨率，可以提高用户体验。
可以理解，若该贴图的内容信息指示该贴图包括预设对象(为至少一个预设对象中的任一个)时，确定对该待渲染场景进行渲染时对预设对象采用1×1个像素点执行一次渲染的策略，并对(该待渲染场景中)除该至少一个预设对象之外的对象采用除1×1个像素点执行一次渲染的策略之外的渲染策略(例如2×2个像素点执行一次渲染的策略)。
示例性地，设置每个预设对象对应的渲染策略的N×M为1×1，除至少一个预设对象之外的对象对应的渲染策略的N×M为4×4。也就是说，若该贴图的内容信息指示该贴图包括预设对象，则确定对该待渲染场景进行渲染时对该预设对象采用1×1个像素点执行一次渲染的策略，并对该待渲染场景中除该至少一个预设对象之外的对象采用4×4个像素点执行一次渲染的策略。
本公开实施例中，该贴图的内容信息指示该贴图包括预设对象，是从贴图的局部的角度考虑的，当贴图的局部为预设对象时，确定对该待渲染场景进行渲染时对预设对象采用该预设对象对应的渲染策略，并对该待渲染场景中除预设对象之外的对象采用其他渲染策略(若该贴图的内容信息指示该贴图不包括任一预设对象(至少一个预设对象中的任一个)时，确定对该待渲染场景进行渲染时采用其他渲染策略)。如此可以灵活确定对该待渲染场景进行渲染时采用的渲染策略，不同对象(不同局部区域)可以采用不同的渲染策略，进而当对该待渲染场景进行渲染时可以对局部采用多像素执行一次渲染的策略，可以提高渲染速度。
可选地，该特征信息还包括该贴图的梯度信息，上述步骤202b具体可以通过下述的步骤202b1实现。
202b1、在该贴图的梯度信息在目标预设梯度范围，且该贴图为目标内容的情况下，确定对该待渲染场景进行渲染时采用该目标内容对应的渲染策略。
可以理解，本公开实施例中，可以先判断该贴图的梯度信息，是否在目标预设梯度范围内，若在目标预设梯度范围内，则若该贴图为目标内容的情况下，确定对该待渲染场景进行渲染时采用该目标内容对应的渲染策略。

示例性地，设置一个预设梯度范围，即目标预设梯度范围中的任一个值均小于或等于梯度阈值的范围。也就是说，若贴图的梯度信息在目标预设梯度范围，则考虑在该贴图为目标内容的情况下，确定对 该待渲染场景进行渲染时采用该目标内容对应的渲染策略；若贴图的梯度信息不在目标预设梯度范围，则无需考虑该贴图是否为目标内容，均确定对该待渲染场景进行渲染时采用预设渲染策略，预设渲染策略可以根据实际情况确定，此处不做限定。
示例性地，设置多个预设梯度范围，目标预设梯度范围为该多个预设梯度范围中的一个，例如，设置三个预设梯度范围，第一预设梯度范围，第二预设梯度范围(即目标预设梯度范围)和第三预设梯度范围。其中，第一预设梯度范围中的任意一个梯度信息均小于第二预设梯度范围中的任意一个梯度信息，第二预设梯度范围中的任意一个梯度信息均小于第三预设梯度范围中的任意一个梯度信息。当贴图的梯度信息在第一预设梯度范围时，可以确定对该待渲染场景进行渲染时采用第一预设梯度范围对应的渲染策略；当贴图的梯度信息在第二预设梯度范围时，且该贴图为目标内容的情况下，确定对该待渲染场景进行渲染时采用该目标内容对应的渲染策略，否则确定对该待渲染场景进行渲染时采用预设渲染策略；当贴图的梯度信息在第三预设梯度范围时，可以确定对该待渲染场景进行渲染时采用预设渲染策略。

可选地，该参数信息包括该每个对象渲染后的深度信息，可以在对待渲染场景进行渲染之前，对待渲染场景进行预渲染(模拟渲染)，以得到待渲染场景中的每个对象渲染后的深度信息；也可以在之前对待渲染场景进行渲染后，保存了待渲染场景中的每个对象渲染后的深度信息，此时可以通过获取之前保存的待渲染场景中的每个对象渲染后的深度信息，以实现获取待渲染场景中的每个对象渲染后的深度信息；还可以通过其他方法获取每个对象渲染后的深度信息，具体可以根据实际情况确定，此处不做限定。进而可以根据每个对象渲染后的深度信息，确定对待渲染场景进行渲染时采用的渲染策略。
可选地，可以在对待渲染场景初次进行渲染之前，不确定渲染策略，默认使用1×1个像素点执行一次渲染的策略；也可以对待渲染场景初次进行渲染之前，通过预渲染的方式获取每个对象渲染后的深度信息，根据每个对象渲染后的深度信息，确定对该待渲染场景进行渲染时采用的渲染策略。然后根据确定的渲染策略对待渲染场景进行渲染之后，保存每个对象渲染后的深度信息；进而下次再对待渲染场景进行渲染之前，可以获取之前保存的每个对象渲染后的深度信息，然后根据每个对象渲染后的深度信息，确定对该待渲染场景进行渲染时采用的渲染策略，然后根据确定的渲染策略对待渲染场景进行渲染之后，更新每个对象渲染后的深度信息。

示例性地，若该多个比例范围为第一比例范围、第二比例范围和第三比例范围，其中，第一比例范围中的任意一个比例值大于第二比例范围中的任意一个比例值(比例范围中的值较小，说明比例范围对应的待渲染场景的不被关注的对象更多，被关注的对象更少，则可以对该比例范围对应的待渲染场景进行更多像素执行一次渲染的策略)，第二比例范围中的任意一个比例值大于第三比例范围中的任意一个比例值，第一比例范围对应的N×M为4×4，第二比例范围对应的N×M为2×2，第三比例范围对应的N×M为1×1。若该占比在第一比例范围内，则确定对该待渲染场景进行渲染时采用4×4个像素点执行一次渲染的策略，若该占比在第二比例范围内，则确定对该待渲染场景进行渲染时采用2×2个像素点执行一次渲染的策略，若该占比在第三比例范围内，则确定对该待渲染场景进行渲染时采用1×1个像素点执行一次渲染的策略。

可以理解，根据每个对象的三角面数量确定每个对象的三角面数量所在的数量范围，然后确定对待渲染场景进行渲染时，对每个对象采用的其三角面数量所在的数量范围对应的渲染策略。
示例性地，若该多个数量范围包括第一数量范围，第二数量范围，第三数量范围，第四数量范围和第五数量范围。其中，第一数量范围中的任意一个值均小于第二数量范围中的任意一个值(数量范围中的值较小，说明三角面数量落在该数量范围的对象越不被关注，渲染时可以采用更多像素点执行一次渲染的策略)，第二数量范围中的任意一个值均小于第三数量范围中的任意一个值，第三数量范围中的任意一个值均小于第四数量范围中的任意一个值，第四数量范围中的任意一个值均小于第五数量范围中的任意一个值；第一数量范围对应的渲染策略的N×M为4×4，第二数量范围对应的渲染策略的N×M为4×2，第三数量范围对应的渲染策略的N×M为2×2，第四数量范围对应的渲染策略的N×M为1×2，第五数量范围对应的渲染策略的N×M为1×1。假设待渲染场景中包括对象1、对象2和对象3共三个对象，其中，对象1的三角面数量在第一数量范围内，对象2的三角面数量在第五数量范围内，对象3的三角面数量在第四数量范围内，则可以确定对待渲染场景进行渲染时，对象1采用4×4个像素点执行一次渲染的策略，对象2采用1×1个像素点执行一次渲染的策略，对象3采用1×2个像素点执行一次渲染的策略。

其中，目标深度范围可以根据实际使用需求确定，目标深度范围对应的渲染策略可以根据实际情况确定，本公开实施例不做限定。
可以理解，对象渲染后的深度信息越大说明对象离镜头越远、越不重要，在屏幕上的尺寸就会越小，可能越不是被关注的对象；反之，对象渲染后的深度信息越小说明对象离镜头越近、越重要，在屏幕上的尺寸就会越大，可能越是被关注的对象。
可以理解，可以设置多个深度范围(目标深度范围为该多个深度范围中的任一个)，不同的深度范围对应不同的渲染策略，不同的渲染策略对应不同的N×M。
可以理解，根据每个对象渲染后的深度信息确定每个对象渲染后的深度信息所在的深度范围，然后确定对待渲染场景进行渲染时，对每个对象采用的其渲染后的深度信息所在的深度范围对应的渲染策略。
