具体实施方式
在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似推广，因此本申请不受下面公开的具体实施的限制。
本申请中使用的术语是仅仅出于对特定实施例描述的目的，而非旨在限制本申请。在本申请中和所附权利要求书中所使用的描述方式例如：“一种”、“第一”、和“第二”等，并非对数量上的限定或先后顺序上的限定，而是用来将同一类型的信息彼此区分。
在对本申请提供的一种飞线的构建方法实施例进行说明前，首先，对飞线进行介绍。飞线是数据大屏上一种数据信息的可视化方式，例如：从起始状态到目标状态的轨迹，其可以是从起始位置到目标位置的轨迹。飞线常规的绘制方式包括：基于svg、canvas、webgl等几种；其中，svg为可缩放矢量图形(Scalable Vector Graphics)；Canvas是HTML5的一部分，允许脚本动态渲染位图像；webgl(全写Web Graphics Library)是一种3D绘图协议，下面介绍三种绘制方式的缺点。
首先，svg和canvas都是基于CPU的绘制方案，缺点是在绘制大量数据的情况下绘制性能急剧下降；因为Svg和canvas绘制方式是先依靠CPU计算动画需要的数据，然后按照计算获得的数据进行绘制；由于浏览器是单线程的，即只能用CPU做计算或者绘制其中一项任务，当大量数据需要绘制的时候，浏览器全部在处理计算任务，绘制任务 得不到计算资源，则导致画面卡顿，进而使得绘制性能急剧下降。
webgl的绘制方式是基于GPU的一种绘制方式，所有计算和绘制都在显卡中进行，对浏览器本身的计算或绘制任务不产生影响，因此海量数据渲染也不会卡顿。在采用webgl实现飞线绘制的方式中，常规的方式有线段法、三角面法、管道法等等，原理均是构建飞线所需的顶点，再进行绘制处理。其中，线段法最容易实现，缺点是webgl环境下原生的线条是不支持宽度的，视觉效果受限制很大；三角面法通过线段法扩展顶点的方法，支持飞线宽度，但是转角的处理复杂、小视角容易出现锯齿；管道法通过线段扩展为管道的方法，支持宽度和小视角观察，但是顶点绘制数量比线段法增加10倍以上，开启透明度的时候容易出现绘制锯齿和瑕疵。
上述任何一种飞线的绘制方式均存在绘制效率低的问题，故此，本申请提供一种飞线的构建方法，能够提高飞线的绘制效率，且避免瑕疵的出现。
请参考图2所示，图2是本申请提供的一种飞线的构建方法实施例的流程图，该构建方法包括：
步骤S201：获取描述物体状态变化的数据信息。
请结合图2参考图3是所示，图3是本申请提供的一种飞线的构建方法实施例中飞线的结构示意图，其中，飞线301有粒子302构成，所述粒子302中实心粒子3021为可见粒子，空心粒子3022为不可见粒子。
所述步骤S201中物体可以是任何一种具有数据信息或产生数据信息的物质，其可以为可见的或不可见的，例如：具有物理结构的物品和不存在真是物理结构的虚拟物品。因此，所述步骤S201的目的在于得到一种能够表达状态变化的数据信息，而该数据信息具体是谁来产生的并不重要，当然，在绘制飞线时可以体现出数据信息的具体内容，因为在本申请提供一种飞线的构建方法中主要涉及的是飞线的构建，因此，重点在于获得具有状态变化的数据信息。
在本实施例中，所述描述物体状态变化的数据信息可以包括至少如下一种数据信息：
用于描述所述物体位置的位置信息；
用于描述所述物体位置对应时间的时间信息。
当然，可以理解的是，数据信息还可以包括物体的一些属性信息，例如：名称，类型，用途等。
在得到物体状态变化的数据信息后，需要去生成表示物体状态变化的粒子，因此，执行步骤S202。
步骤S202：根据所述数据信息，生成用于表示物体状态变化的粒子。
所述步骤S202的目的在于，获得构成飞线的元素，也就是说，飞线是通过粒子实现构建而成。在本实施例中，所述步骤S202中的粒子可以通过粒子系统生成。所述粒子系统是运用于计算机中各种模糊景物的模拟，其主要解决由大量按一定规则运动(变化)的微小物质组成的大物质，在计算机上的生成与显示问题。通常可以模拟的现象有火焰、爆炸、烟、水流、火花、落叶、云、雾、雪、尘、流星尾迹或者像发光轨迹这样的抽象视觉效果等等，也就是说，粒子系统可以描述组成物体的每个元素和元素的变化。
粒子系统的构成包括：粒子和发射器。其中，粒子包括形状、大小、颜色、透明度、运动速度和运动方向、生命周期等属性，在粒子系统中通过粒子对象的类(particle)实现粒子属性的可视化。发射器用来对生成粒子的发射情况进行控制。
粒子系统通常分为两种：点粒子和四边形粒子。点粒子是指所有粒子都是由点构成；四边形粒子是将一个粒子纹理给映射到一个四边形上，作为一个粒子对象。由于点粒子可以根据顶点粒子的属性生成下一个粒子，无需过多的顶点信息，因此，在本实施例中，可以点粒子的方式进行飞线构建的说明。当然，可以理解的是，可以通过对粒子的构建方式的选择构建满足需求的飞线形状。
基于上述内容可知，所述步骤S202生成表示物体状态变化粒子的具体过程可以包括：
步骤S202-1：根据所述数据信息确定待生成粒子的属性。
在本实施例中，所述待生成粒子的属性可以至少包括确定如下一种属性：
描述待生成粒子形状的属性；
描述待生成粒子位置状态变化的属性；
描述待生成粒子状态变化时间的属性；
描述待生成粒子大小的属性；
描述待生成粒子颜色的属性。
所述生成粒子的属性可以根据构建飞线的需求，通过数据信息确定，例如：飞线的形状可以通过粒子的形状属性进行确定，也就是说，飞线的可视化形状可以通过粒子的属性确定。
步骤S202-2：根据所述待生成粒子的属性，确定粒子结构。
在粒子系统中，粒子的属性确定粒子的结构情况，因此所述步骤S202-2，可以根据所述待生成粒子的属性，确定粒子结构。
基于现有技术中存在的通过增加顶点的方式扩充飞线的宽度，导致绘制性能和效率下降的问题，在本实施例中仅需要通过粒子系统对粒子的半径调节，即能够实现飞线宽度的调节，无需构建多个顶点，避免绘制性能和效率下降的问题，故，所述步骤S202-2中可以包括：基于绘制所述物体状态变化轨迹宽度的要求，根据描述所述粒子大小的属性，确定粒子半径，从而完成粒子宽度的调节。
本实施例通过粒子系统中设置的粒子半径的自定义调节，不仅能够完成粒子宽度的设置，还能够在任何视角或场景下，避免飞线的局部或全部不可见或产生锯齿等瑕疵问题。需要说明的是，此处的不可见是指在飞线可见的显示要求下，发生不可见的情况，也就是无法正常显示的问题。
步骤S202-3：根据所述粒子结构生成用于绘制所述物体状态变化轨迹中描述状态变化的粒子。
所述步骤S202-3的目的在于，需要根据确定的粒子属性，确定粒子的结构，再根据粒子结构生成用于绘制所述物体状态变化轨迹中描述状态变化的粒子。例如：飞线用于描述行人的运动轨迹，那么，可以根据行人移动的时间点，生成该行人相对该时间点的粒子，时间点的信息为粒子属性；不同时间点可以对应该行人的不同位置，以上仅以行人的运动轨迹为举例说明。当然，还可以在生成粒子时设置粒子大小属性，即根据该行人的时间属性、预设的粒子大小属性生成粒子。本申请中粒子的生成可以采用现有粒子系统实现，因此描述的较为概要。
在根据粒子结构生成粒子后，每个粒子均具有属性信息，在本实施例中，主要采用粒子的位置属性和时间属性，描述粒子的变化状态，而所述位置属性和时间属性可以通过获取的描述物体状态变化的数据信息确定，因此，生成后的粒子会携带有位置属性和时间属性的信息。
在根据所述物体状态变化的数据信息生成用于表示物体状态变化的粒子后，可以根据粒子生成用于描述物体状态变化轨迹的飞线，具体如下：
步骤S203：根据预设位置范围内的粒子生成用于描述物体状态变化轨迹的飞线。
所述步骤S203中的预设位置范围可以是根据显示需求确定，例如：物体状态变化过程中的起始点和结束点，所述起始点和结束点可以看做是顶点。飞线可以是描述物体状态变化轨迹的一种可视化线条，可以理解为，由多个不同或相同形状的点构成的线条。线条的延伸方向可以看做是物体状态变化的方向。因此，所述步骤S203可以包括：
步骤S203-1：确定起始位置和结束位置。
所述步骤S203-1中的起始位置和结束位置可以理解为飞线的起始位置和结束位置，所述起始位置可以根据起始位置处的粒子信息确定，结束位置可以根据结束位置处的粒子信息确定。确定的方式可以通过按照粒子的时间属性实现，因为，粒子描述物体状态变化的信息，物体状态变化的信息可以包括：位置状态的变化信息和时间状态变化的信息，当然还可以包括形状变化的信息或者大小变化的信息等等，在本实施例中，主要以位置和时间变化信息为主进行说明。
换言之，所述步骤S203-1可以根据时间的变化确定飞线顶点处(起始处)的粒子信息和飞线结束处的粒子信息，例如：将物体状态变化时间最早所对应的位置确定为起始位置，所述最早可以是在描述物体状态变化的范围内的最早或最小，如描述物体状态变化的时间范围为上午的7:00-10:00，则可以将7:00所对应的物体状态变化的位置确定为起始位置，7:00为起始时间；10:00对应的物体状态变化的位置确定为结束位置，10:00为结束时间，依照该时间范围构建的飞线，表达从7:00到10:00之间物体状态变化的轨迹。飞线的生成可以通过步骤S203-2实现。
步骤S203-2：按照粒子状态变化的时间属性，依序连接位于所述起始位置和所述结束位置之间的粒子，获得用于描述所述物体状态变化轨迹的飞线。
所述步骤S203-2的具体实现可以通过粒子系统中发射器实现，例如：根据粒子状态变化的时间属性，确定初始位置处的第一粒子，发射器确定第一个发射的粒子，接着将排序在所述初始位置处后且与初始位置的第一粒子相邻的第二粒子确定为第二个发射的粒子，依序进行，从而获得用于描述所述物体状态变化轨迹的飞线，换言之，可以按照粒子状态变化的时间顺序，通过设置发射器将粒子依序连接，获得用于描述所述物体状态变化轨迹的飞线。
可以理解的是，对于飞线的生成可以采用位置信息确定飞线起始位置(顶点)的粒子和结束位置的粒子，从而根据起始位置和结束位置生成飞线。也可以通过采用位置信息和时间信息确定飞线起始位置(顶点)的粒子的时间信息和确定飞线结束位置的粒子的时间信息，从而根据位置和时间两个元素生成飞线。本实施例中，主要采用位置和时间两个元素对生成飞线的过程进行说明，在其他一下实施例中也可以仅采用位置元素生成飞线。
本实施例中，飞线基于粒子生成，无需大量的顶点信息，仅需要根据粒子的属性信息即可生成，因此，提升了构建性能。另外，飞线的构建基于GPU的计算能力完成，即在显卡中进行，对浏览器本身的计算或绘制任务不产生影响，因此，对海量数据渲染也 不会造成卡顿，进而能够在海量数据的环境下提升飞线构建或绘制的效率。
为实现飞线的动态显示要求，体现不同时间范围飞线的不同状态，以及体现各个飞线之间的时间关系，本申请提供的飞线的构建方法还可以包括：
步骤S204：根据飞线的显示要求，确定描述所述飞线中粒子可见性的可见性信息。
所述步骤S204的目的在于通过控制粒子的可见性能够根据显示需求实现飞线个性化显示，在具有多飞线的应用场景下，也能够体现出各个飞线的时间关系，即数据信息的时间关系。同样的也可以通过粒子的可见性体现飞线的不同状态，所谓不同状态可以为物体状态变化的重要程度。
基于上述步骤S201-S203可知，飞线构建过程是通过将多个粒子按照状态变化时间属性依序连接实现，每个粒子可以代表物体一个状态变化，为体现状态变化的动态可视效果，所述步骤S204可以包括：
步骤S204-1：确定构成所述飞线的粒子的显示时间要求。
所述步骤S204-1中对于粒子的显示时间要求可以是针对飞线而言，即需要显示飞线区域所对应的粒子的显示时间要求，因为粒子带有自身状态变化的时间信息，因此在确定显示时间要求后能够确定与该显示时间要求匹配的粒子时间信息。沿用上例，如果飞线的显示时间范围7:00-10:00，即显示时间为7:00-10:00的物体状态变化轨迹的飞线，确定的粒子显示时间要求可以为7:00-8:30。
所述步骤S204-1的具体实现过程在本实施例中可以包括：
步骤S204-1a：根据所述飞线的显示要求，构建时间掩膜。
为便于理解，请参考图3所示，可以将时间掩膜303看做是一个具有时间参数的蒙板，蒙板覆盖飞线区域为可见区域，未覆盖区域为不可见区域；当然也可以理解为，蒙板覆盖飞线区域为不可见区域，未覆盖区域为可见区域。
步骤S204-1b：根据所述时间掩膜，确定构成飞线的粒子的显示时间要求。
所述步骤S204-1b目的在于，在构成飞线的粒子中选取时间信息满足显示时间要求的粒子，时间掩膜可以控制粒子的可见性。
步骤S204-2：将时间信息满足显示时间要求的粒子，按照所述粒子状态变化的时间属性依序进行显示。
所述步骤S204-2的目的在于，将飞线中满足显示时间要求的粒子进行显示。例如：当时间掩膜的显示时间范围要求为7:00-8:30，则可以在飞线显示时间范围为7:00-10:00内显示7:00-8:30的飞线部分，即：将显示时间要求为7:00-8:30的粒子按照粒子状态变 化的时间属性依序进行显示，形成描述物体状态变化轨迹的飞线。
为使飞线能够动态的可视化显示，所述步骤S204-2还可以包括：
步骤S204-2a：根据所述粒子显示时间要求，确定所述时间掩膜的移动范围。
所述步骤S204-2a所述时间掩膜的移动范围可以是调整所述时间掩模的开始时间和结束时间。
步骤S204-2b：对所述时间掩膜的移动范围内的所述粒子依序进行显示。
所述步骤S204-2b具体的实现过程可以是不断调节或更新所述时间掩模的开始时间和结束时间，即可过滤出动态可见的粒子，形成飞线的动态可视化显示。
需要说明的是，本实施例中构建飞线可以根据不同需求设置显示要求，例如：需求是飞线起始位置到结束位置之间呈现出某一时间范围内的飞线，则可以通过时间掩膜所设置的时间范围，显示满足时间掩膜的飞线，通过对时间掩膜的起始时间和结束时间的调整，使得飞线呈动态的显示形式。
可以理解的是，在飞线的显示效果上，还可以通过对时间掩膜透明度的设置，使得在时间掩膜范围内的飞线可以呈现出不同亮度的显示效果。
因此，时间掩膜可以理解为一个具有时间参数的蒙板，蒙板覆盖飞线区域为可见区域，未覆盖区域为不可见区域；当然也可以理解为，蒙板覆盖飞线区域为不可见区域，未覆盖区域为可见区域。通过调整蒙板的透明度使得可见区域以亮度渐变状态显示。
