WPF effects-Fish Swim Animation 3

Original: WPF effects-Fish Swim Animation 3

WPF does not support bones, so use 3DMax to export the sequence model file (. MTL;. obj).

Method 1:

Use blend 2013 to open all obj files, drag and arrange to display in UserControl, use RenderTargetBitmap to generate PNG sequence diagrams, and use a timer to play sequence diagrams.

Method 2:

? WPF has many class libraries that dynamically load obj model files, and dynamically loads all of the obj files using the loop method to dynamically generate a sequence diagram for each obj. (not yet tried, theory is no problem).

Method 3:

? Using Unity3d to open the exported skeleton model file, the resulting PNG sequence diagram is loaded in WPF (not yet tried).

Method One detailed:

1. Blend open obj sequence and arrange (blend project can be opened with VS, effect rendered in VS, 5 obj file used for testing)

2. Using RenderTargetBitmap to generate a PNG sequence diagram

 string sTargetFile = AppDomain.CurrentDomain.BaseDirectory + "Fish1.png";            RenderTargetBitmap oRenderTargetBitmap = new RenderTargetBitmap((int)this.GdMainZm.Width,                (int)this.GdMainZm.Height, 96, 96, PixelFormats.Pbgra32);            oRenderTargetBitmap.Render(this.GdMainZm);            PngBitmapEncoder oPngEncoder = new PngBitmapEncoder();            oPngEncoder.Frames.Add(BitmapFrame.Create(oRenderTargetBitmap));            using (Stream stm = File.Create(sTargetFile))            {                oPngEncoder.Save(stm);                stm.Close();            }

? The PNG generated after the run is as follows:

3. Use the timer to play the sequence diagram

  private ImageSource imagesrc;        Private DispatcherTimer Timerplay;        private int Index =-1; private void Fishitem8_loaded (object sender, RoutedEventArgs e) {this.            Loaded-= fishitem8_loaded; Asynchutils.asynchdelayexecutefunc (() = {this.                Timerplay = new DispatcherTimer (dispatcherpriority.systemidle); This.                Timerplay.interval = Timespan.fromseconds (0.3); This.                Timerplay.tick + = Timerplay_tick; This.            Timerplay.start (); }, Utilitys.getrandomseed ().        Nextdouble ());            } private void Timerplay_tick (object sender, EventArgs e) {index++;            if (index >= 5) index = 0; BitmapSource osource = new Croppedbitmap (Bitmapframe.create ((BitmapSource) imagesrc), New Int32Rect (300*In            Dex, 0, 300, 180)); This.        Imgmainzm.source = Osource; }

5. Only 5 obj files are used for testing, the number of sequence frames is too small, so the fish action is more rigid, enough to avoid, for example, before I started to download the WinForm version of the demo:

? The code friend uses the sequence diagram as follows (about 20, frame, swimming effect is great):
