为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获取其他的附图。

下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，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取的所有其他实施例，都属于本公开保护的范围。
本公开提供了一种显示处理方法，如图1所示，该显示处理方法应用于旋转立体显示装置，旋转立体显示装置包括显示面板，显示面板可转动设置。
在一个实施例中，该显示面板的一端固定于一转轴上，实施时，通过驱动该转轴旋转能够实现带动显示面板绕该转轴旋转。
显然，在其他一些实施例中，还可以通过其他方式带动显示面板旋转，例如，通过将显示面板固定于一可旋转的底座上等方式，同样能能够实现控制显示面板转动。
请继续参阅图1，本实施例中以转轴位于显示面板的一侧边为例说明，屏幕在转轴的带动下绕该转轴旋转，这样，相当于形成一圆柱状的显示空间。屏幕每旋转一周，相当于刷新一帧图像，由于该图像呈现三维立体效果，因此，本实施例中将每一帧图像称作一个体帧。
一般来说，人眼视觉暂留效应要求体帧的帧率不小于24Hz，因此显示面板每秒钟至少需要刷新24个体帧，也就是说，显示面板的旋转速度不小于每秒24周(24r/s)。
进一步的，显示面板在不同位置显示的内容是不同的，因此，需要定义多个相位，显示面板在不同相位显示不同的内容。本实施例中以间隔2°定义为一个相位为例说明，则每一体帧具有180个相位，分别对应180幅截面图形。因此，该显示面板的刷新频率不小于180*24＝4320Hz。
显示，实施时，相位的具体数量可以相应的增加或减少，显示面板的旋转速度同样可以做出适应性调整，进一步的，可以根据显示面板的旋转速度和相位数量确定显示面板的刷新频率。
记屏幕的分辨率为width×height，其中，width为横向分辨率，height为纵向分辨率，相邻像素的中心距离为pitch、像素边长为side，屏幕的像素绕转轴旋转时，在空间中的显示位置称为每一体帧的体素。
本公开的发明人在实现本申请的技术方案过程中发现，为了生成显示数 据，可以先确定该旋转立体显示装置的显示空间的尺寸。
如图1所示，以显示面板绕其一端旋转为例说明，在显示面板静止时，其显示区域形成一二维显示平面，当显示面板旋转时，显示面板的旋转范围形成一圆柱状显示空间，该圆柱状显示空间的半径为显示面板的宽度，该圆柱状显示空间的高为显示面板的高度。
接下来，将图像模型通过平移和缩放操作，使该图像模型完整的位于该显示空间内。
进一步的，根据该图像模型确定显示面板在每一相位显示的图像，并在显示面板移动至相应的相位时，显示该图像即可。
然而对显示数据处理过程中，针对每一相位对应的图像，均需要进行一次模型的网格化处理(mesh)，以获取相应的显示数据，如果显示的画面为包括多个动画帧的动态图像，则每一动画帧均需要进行多次模型mesh，工作量较大。
本公开发明人进一步提出以下技术方案。
在一个实施例中，如图2所示，该显示处理方法包括以下步骤：
步骤201：获取待显示图像中的图像模型的模型信息。
本实施例中，待显示图像可以为静态图像，也可以为动态图像，相应的，其显示模型可以为静态的图像模型，也可以为动态的图像模型，图像模型包括至少一个属性集合。
属性集合指的是按照相同的属性划分的三角面集合，本公开实施例进一步以三角面的材质作为划分属性集合的特征做进一步说明，这样，每一属性集合也称作一个材质集合，同一材质集合中三角面的材质相同。
显然，在其他一些实施例中，还可以考虑以三角面的颜色、三角面的位置等属性进行属性集合的划分。
每一材质集合包括构成图像模型的多个三角面，可以理解为，每一图像模型实际上是由多个小尺寸的三角面构成的，本实施例中，设置了一个或多个材质集合，以便于管理这些三角面。
应当理解的是，一个图像模型的不同部分可能相同，也可能存在一定的差异，本实施例中将相同的三角面划分至同一材质集合。
换句话说，如果构成一个图像模型的三角面的材质均是相同的，那么可以设置一个材质集合容纳这些三角面；如果构成一个图像模型的三角面包括两种或两种以上材质，那么，可以相应的设置多个集合，并将材质相同的三角面划分至同一材质集合。
材质集合中的数据还可能包括其他与三角面属性相关的数据，具体的，包括但不限于材质集合的名称、材质相关参数、坐标相关参数等。例如，材质相关参数可能包括环境光系数、材质的漫反射系数、镜面反射系数、自然光系数、光滑系数、贴图文件等，坐标相关参数可能包括三角面的顶点坐标相关参数、顶点法线相关参数、纹理相关参数、面法线相关参数等。
步骤202：根据材质集合的关联关系，遍历每一所述材质集合中各三角面的顶点的坐标信息。
本实施例中模型信息的数据结构进一步还包括材质集合的关联关系，该关联关系用于实现对于材质集合的索引，以实现遍历各材质集合中的数据，具体的，为材质集合追踪包含的三角面的顶点的坐标信息
步骤203：根据每一所述三角面的顶点的坐标信息生成所述显示面板在每一相位的显示数据。
在确定了个三角面的顶点的坐标信息之后，进一步结合显示面板的相位信息，能够获得现实面板在每一相位的显示数据。
在本公开的一些实施例中，该步骤203具体包括
根据所述三角面的标记信息确定所述显示面板在各相位与所述三角面的相位交线；
根据所述相位交线生成所述显示面板在相应相位的显示数据。
如图3所示，首先确定各个相位的截面方程，然后根据截面方程和图像模型的数据求交集，该交集也就是每一相位的截面与图像模型的相位交线，本实施例中又将其称作理想交线。
由于显示面板上的像素是离散的，因此，根据显示面板上像素显示的图像可能难以完全与该理想交线一致，因此，需要进一步根据显示面板上像素分布拟合该理想交线，拟合结果也就是实际显示效果，本实施例中将其称作近似交线。
步骤204：在所述显示面板位于各相位时，根据各相位的显示数据显示画面。
请继续参阅图3，在确定每一相位对应的近似交线之后，将所有相位的近似交线按照相位顺序，也就是旋转角度的顺序依次编排，并在显示面板位于指定的相位时，显示相应的图像，例如，在显示面板旋转至第一个相位时，控制显示面板显示与该相位对应的图像，在显示面板旋转至第二个相位时，控制显示面板显示与该第二相位对应的图像，依此类推，即可实现通过旋转显示装置显示三维立体图像。
本公开实施例通根据材质集合的关联关系，只要对图像模型进行一次网格化处理，即可实现获取图像在各个相位的相位角线，也就是显示面板在各个相位的显示数据，有助于降低数据处理数量，提高显示数据处理效率。
在本公开的一些实施例中，图像模型包括N个材质集合，N为正整数。
在本实施例中，上述步骤202包括：
确定所述图像模型的根节点；
根据所述根节点与第一个材质集合之间的索引关系索引第一个材质集合，并获取所述第一个材质集合中三角面的顶点的坐标信息；
在N大于1的情况下，根据第M-1个材质集合中包含的索引信息索引第M个材质集合，并获取所述第M个材质集合中三角面的顶点的坐标信息，依此类推，直至获取全部材质集合中各三角面的顶点的坐标信息，其中，M为小于或等于N，且大于1的正整数。
本实施例，材质集合的关联关系包括根节点与材质集合之间的关联关系，遍历材质集合的起始阶段，首先由根节点索引第一个材质集合，以获取该第一个材质集合中包含的各三角面的顶点的坐标信息，该第一个材质集合指的是直接与根节点关联的材质集合。
如图4A所示，在材质集合的数量为一个的情况下，也就是N等于1的情况下，在遍历第一个材质集合之后，实际上已经完成了对于全部材质集合的遍历。
请继续参阅图4A，在材质集合的数量多于一个的情况下，也就是N大于1的情况下，材质集合的关联关系还包括不同材质集合之间的关联关系，具 体的，每一材质集合具有指向下一材质集合的节点指针，其中，最后一个材质集合的节点指针为空，这样，在遍历一个材质集合，并获取了该材质集合中三角面的顶点的坐标信息之后，根据该节点指针能够实现对下一个材质集合的索引，依此类推，直至索引到为空的节点指针，就完成针对全部材质集合的遍历，并获取全部材质集合中三角面的顶点的坐标信息，进一步，还可以获取法向量、面法线、顶点法线等和图像模型相关的信息。
这样，本实施例通过根据材质集合的关联关系，实现了由根节点索引第一个材质集合，并进一步完成全部材质集合的索引，有助于降低工作量，提高数据处理效率。
应当理解的是，在待显示的图像为静态图像时，待显示图像中的图像模型也为静态模型，在显示面板旋转的多个周期内，显示面板在同一位置显示的图像是相同的，因此，当显示面板移动至指定的相位时，只要显示特定的图像即可。而待显示的图像为动态图像时，待显示图像中的图像模型也为动态模型，在显示面板旋转的多个周期内，显示面板在同一位置显示的图像可能存在差异，因此需要进一步调整显示面板显示的图像。
在本公开的一些实施例中，所述图像模型多个关节节点；
所述遍历每一所述属性集合中各三角面的顶点的坐标信息，还包括：
获取所述图像模型的动画帧信息；
根据所述动画帧信息计算各关节节点在每一所述动画帧内的坐标信息；
根据所述关节节点的坐标信息计算各三角面的顶点的模型坐标。
如图4B所示，在图像模型为动态模型的情况下，本实施例中进一步获取动画帧信息，每一动画帧中的图像模型可以理解为一个静态模型，通过获取不同动画帧信息，能够获取各关节节点在不同动画帧中的位置变化信息。
在确定了关节节点在不同动画帧中的位置变化信息之后，根据关节节点与三角面的顶点之间的关联关系计算出个三角面的顶点坐标，并进一步确定三角面顶点的模型坐标。
进一步的，在一个实施例中，待显示图像中的图像模型为动态模型，图像模型包括骨骼和蒙皮，每一所述骨骼位于相邻两个关节节点之间，蒙皮与骨骼相绑定，蒙皮由至少一个材质集合构成。
所述根据所述关节节点的坐标信息计算各三角面的顶点的模型坐标，包括：
根据所述关节节点的坐标信息确定所述骨骼的坐标信息；
基于所述蒙皮和所述骨骼的绑定关系，根据所述骨骼的坐标信息计算各所述三角面的顶点的坐标信息。
实施时，首先由根节点索引材质集合并进一步获取其中的三角面相关信息，进一步的，本实施例中还需要索引关节节点，并进一步获取动画帧信息，根据动画帧信息计算各关节节点的位置。接下来，根据关节、骨骼以及三角面之间的关联关系确定关节对于三角面顶点的影响程度，以结合关节对于三角面的顶点位置的影响，更新三角面的顶点的坐标信息。
动画帧信息中至少应当包括该动画帧的时刻、序号、其中的关节节点、相邻关节之间的变换关系T_anim，以及指向下一动画帧的动画帧指针，其中，当动画帧为最后一帧时，该动画帧指针为空。
如图5A所示，骨骼可以理解为位于两个关节节点之间具有固定属性的框架，因此，在确定了各关节节点的坐标信息之后，也就能相应确定位于关节节点之间的骨骼的位置变化信息。
如图5A和图5B所示，蒙皮与骨骼相绑定，因此，确定了骨骼的位置变化信息之后，进一步可以根据骨骼的运动信息得到蒙皮的位置变化信息。实施时，首先根据蒙皮与骨骼的位置关系，确定影响蒙皮每一部分的骨骼，并进一步根据该骨骼的位置变化信息确定蒙皮的位置的更新。
本实施例中，显示数据中的关节信息至少包括关节的节点信息、关节名称、关节序号。进一步的，关节之间还可能存在一定关联关系和主从关系，在关节存在上一级关节时，或称存在父关节时，进一步还可以包括父关节的信号、关节与父关节之间的变换关系记作T_pc；由于蒙皮和骨骼是绑定的，也就是说，三角面的顶点坐标和关节之间存一定绑定关系，其变换关系记作T_cv；关节和模型坐标之间的变换关系记作T_mc。
如图5C所示，以共计包括joint0至joint2共计三个关节为例说明，这三个关节依次关联，实施时，先根据相邻关节之间的变换关系T_anim更新相邻关节之间的变换关系T_pc0、T_pc1和T_pc2的值，进一步获得关节与模型坐 标之间的变化关系如公式(1)所示。
由于根据蒙皮和骨骼的关联关系，提取顶点到关节的坐标变换参数T_cv和关节到模型的坐标变换参数T_mc结合公式(1)完成顶点位置的更新。
如图5C所示，在一个实施例中，蒙皮包括三角面ABC，顶点A绑定的关节索引joint_indices为[1,2]，即图5C中joint1和joint2，其权重joint_weights为[m,n]，这里，权重指的是关节对于顶点的影响大小，具体由关节和顶点之间的关联关系确定。关节joint1的两个分别变换矩阵为T_mc1和T_cv1，关节joint2的两个变换矩阵为T_mc2和T_cv2，则可以进一步通过以下公式(2)实现对于顶点A的模型坐标的跟踪和更新。
p_model1＝(T_mc1×T_cv1×m+T_mc2×T_cv2×n)×p_model0……(2)
其中，p_model0和p_model1分别为顶点A更新前和更新后的模型坐标。
在本公开的一些实施例中，坐标信息包括模型坐标、场景坐标、设备坐标和标记信息。
上述步骤202包括：
确定每一所述三角面的顶点的设备坐标，所述设备坐标为所述基于所述旋转立体显示装置建立的设备坐标系中的坐标；
根据所述显示面板的相位信息和所述设备坐标生成各所述顶点的标记信息。
应当理解的是，显示面板的相位和图像模型是通过基于旋转立体显示装置建立的设备坐标系确定其相对位置关系的，因此，本实施例中，首先确定三角面的设备坐标，然后根据显示面板的相位信息确定三角面各顶点的标记信息。
在一个实施例中，确定每一所述三角面的顶点的设备坐标的步骤包括：
获取每一所述三角面的顶点的模型坐标，所述模型坐标为图像模型坐标系中的坐标；
根据所述模型坐标计算各所述三角面的顶点的场景坐标，所述场景坐标为图像场景坐标系中的坐标；
根据所述场景坐标计算各所述三角面的顶点的设备坐标。
本实施例中，模型坐标为图像模型坐标系中的坐标，也就是说，在基于图像模型单独建立的坐标系中的坐标，主要体现在图像模型中的相对位置；场景坐标为图像场景坐标系中的坐标，体现了图像模型在场景中的相对位置；设备坐标为基于旋转立体显示装置建立的设备坐标系中的坐标，体现了与显示面板或与转轴等硬件设备的相对位置。具体可以通过以下公式计算。
p_devece＝T_ds×p_scene＝T_ds×T_sm×p_model……(3)
上述公式(1)中，p_model为模型坐标，T_sm为模型坐标和场景坐标之间的换算关系，p_scene为场景坐标，T_ds为场景坐标和设备坐标之间的换算关系，p_devece为设备坐标。
在确定了设备坐标后，进一步基于设备坐标生成标记信息。如图6A和图6B所示，标记信息用于标记三角面的定点与显示面板旋转过程中的各相位之间的位置关系。
图6A中ABC为一个三角面，图中仅示出了相邻的相位i和相位i+1，请继续参阅图6A和图6B，顶点B位于相位i和相位i+1之间，也就是说，本实施例中将其标记为B(i,1+1)，同理，进一步可以标记顶点A为A(i-1,1)，顶点C为C(i+1,1+2)。依此类推，可以确定各个顶点的标记信息。
实施时，由上述公式(4)计算顶点的偏转角度θ，然后根据偏转角度θ计算标记信息p_sign。上述公式中，p_decive.y和p_device.x分别为图6B所示坐标系xoy中的场景坐标y和场景坐标x；sections代表相位的总数量，例如，本实施例中每2°为一个相位，共计包括180个相位，则sections的值为180；floor()函数为向下取整函数。这样，通过上述公式能够计算出每一顶点的标记信息。
在确定了每一三角面的顶点的标记信息之后，也就能够确定与该三角面相交的相位信息。请参阅图6A，三角面ABC的顶点的标记信息为A(i-1,1)、B(i,1+1)，C(i+1,1+2)，因此，可以确定，三角面ABC的边AB穿过相位 i，AC穿过相位i和相位i+1，BC穿过相位i+1，进一步可以确定三角面ABC的边和相位i有两个交点，记为D和E，三角面ABC的边和相位i+1有两个交点，记为M和N，则进一步能够确定三角面和相位i的理想交线为线段DE，和相位i+1的理想交线为MN。
本公开实施例还提供了一种显示处理装置，应用于旋转立体显示装置，所述旋转立体显示装置包括显示面板和转轴，所述显示面板设置于所述转轴上，且能够绕所述转轴旋转。
如图7所示，所述显示处理装置700包括：
