平移矩阵表示用来对物体进行平移变换,只需将三维物体乘以平移矩阵就可以实现平移效果,在表中Tx,Ty和Tz分别表示沿着不同方向进行缩放的比例.

动画编程 实现动画的原始办法是配置一个定时器,然后根据定时器的频率循环的回调.在回调方法中,可以手动更新目标属性,根据时间的变化用数学计算来决定当前值,直到它达到最终值,这时就可以停止定时器,并移除时间处理程序.

可以使用一个效果相同的PointAnimationUsingKeyFrames对象代替上面的PointAnimation对象.
1 2 3 4 5 <PointAnimationUsingKeyFrames Storyboard.TargetName="myradialgradientbrush" Storyboard.TargetProperty="GradientOrigin" AutoReverse="True" RepeatBehavior="Forever" > <LinearPointKeyFrame Value="0.1,0.7" KeyTime="0:0:0" /> <LinearPointKeyFrame Value="0.3,0.7" KeyTime="0:0:10" /> </PointAnimationUsingKeyFrames>
这个动画包含两个关键帧,当动画开始时第一个关键帧设置Point值(如果希望在RadialGradientBrush画刷中设置的当前值,可以省略这个关键帧).第二个关键帧定义结束值,这是10秒之后到达的数值,PointAnimationUsingKeyFrames对象执行线性插值,这样第一个关键帧平滑移动到第二个关键帧,就像PointAnimation对象使用From值和To值一样.
1 <SplineDoubleKeyFrame Value="500" KeyTime="0:0:7" KeySpline="0.0,1.0 1.0,0.0" />
样条关键帧根据KeySpline属性的值在值之间创建可变的过度,KeySpline属性是从(0,0)延伸到(1,1)的贝塞尔曲线的两个控制点，用于控制在该顶点两侧的曲线的弧度,描述了动画的加速.第一个控制点控制贝塞尔曲线前半部分的曲线因子,第二个控制点控制贝塞尔线段后半部分的曲线因子.此属性基本上定义了一个时间关系间的函数,其中函数-时间图形采用贝塞尔曲线的形状,所得到的曲线是对该样条关键帧的更改速率所进行的描述.曲线陡度越大,关键帧更改其值的速度越快,曲线趋于平缓,关键帧更改其值的速度也趋于缓慢.

有一种动画类型是可以将动画化的值应用于其类型不是Double,Point,Color的属性的唯一方法,它就是关键帧动画ObjectAnimationUsingKeyFrames.使用Object值的动画非常不同.因为不可能在帧之间插入值.当帧的KeyTime到达时,动画化的值将立即设置为关键帧的Value中指定的值,由于没有任何插入,因此只有一种关键帧用于ObjectAnimationUsingKeyFrame.关键帧集合:DiscreteObjectKeyFrame.DiscreteObjectKeyFrame的Value通常使用属性元素语法设置.因为设置的对象值通常不可表示为字符串以采用属性语法填充Value.如果使用引用,例如StaticResource,则可以使用属性语法.

11.2.绑定集合集合.类是实现了INotifyCollectionChanged接口的数据集合类,使用ObservableCollection类的实例与列表控件及进行绑定可以动态地往数据源地集合对象增加或删除数据,并且可以把这种变更通知到UI上,这就是ObservableCollection类最大地特点.,Collection等.,Collection等集合适合于绑定静态数据,也就是绑定了列表控件之后就不需要再对项目进行插入和删除操作.

图表编程 13.1.动态生成折线图和区域图
1 <Polyline Stroke="LightBlue" StrokeThickness="5" Height="150" Points="0,10 50,40 100,90 150,50 200,50 250,10 300,100 350,30 400,0" />
区域图的规则和折线图是类似的,只不过区域图是一个闭合的图形,相当于把折线图和X轴组合起来形成一个区域,区域图可以通过Polygon图形去实现,Polygon图形和Polyline图形的区别在于一个是闭合的而另一个是非闭合的,这也是区域图和折线图的区别.
1 <Polygon Fill="AliceBlue" StrokeThickness="5" Height="150" Stroke="Red" Points="0,150 0,10 50,40 100,90 150,50 200,50 250,10 300,100 350,30 400,0 400,150" />
13.12.生成图形逻辑封装
1 2 3 4 5 6 7 8 9 10 11 12 13 14 private PointCollection GetLineChartPointCollection(List<double> datas,double topheight,double perWidth,double topValue) { PointCollection pointCollection=new PointCollection(); double x = 0;//X坐标 foreach (var data in datas) { double y; //Y坐标 if (data > topValue) y = 0; else y = (topheight - (data * topheight) / topValue); Point point =new Point(x,y); pointCollection.Add(point); x += perWidth; } return pointCollection; }
该方法通过参数传递进行折线图表展示的数据集合,图表的最高高度,两个数据之间的X轴的间隔和图表数值的最大的值,j然后根据这些数据来产生一个坐标的点集合.图表数值的最大值是为了控制数据集合里面的数值相差太大而导致图表显示异常,所以做了一个最大值的控制.如果datas数据里面有比topValue大的数据,将会用topValue来代替,Y坐标的产生公式是y=(topHeight-(data*topHeight)/topValue),计算出点和顶部的距离就是Y坐标,X坐标就是有规律地递增.

生成区域图,如果直接使用Polygon图形来生成区域图,只需要在GetLineChartPointCollection方法里面添加上一个开始点在X轴的映射坐标和一个结束点在X轴的映射坐标就可以了.除了使用Polygon图形来实现,还可以用Path图形来实现,实现的效果也是一样的.

13.32.定义线性数据图形类

上面的DataSeries类只是封装了单个线性图形的基本属性和形状,下面再定义一个DataCollection类表示图形数据集合类,用于实现把线性图形按照定义的坐标体系添加到界面的面板上
