Creating an accelerated graphics viewport in Java Encoder QR Code JIS X 0510 in Java Creating an accelerated graphics viewport

Creating an accelerated graphics viewport use java qr codes development toencode qr code on java Visual Studio Development Tools and Languages So far, we jdk QR Code ISO/IEC18004 have prepared a development environment to develop games using Silverlight 3, and we have created some digital art assets for new remakes of an old game. We have developed a very simple Silverlight and XBAP WPF application to show a ghost moving like a mouse pointer. However, games require something more impressive.

How can we exploit modern hardware in Silverlight to accelerate the production of real-time graphics on the screen . Working with 2D Characters WPF applic Denso QR Bar Code for Java ations take advantage of the power offered by modern GPUs (Graphics Processing Units), also known as accelerated graphics cards. This specialized hardware runs common and complex procedures related to 2D and 3D graphics, and they free the CPU (Central Processing Unit) from this weight load. Unfortunately, Silverlight 3 does not take full advantage of modern GPUs.

However, it offers the possibility to use the GPU for some operations. Under certain circumstances, we can improve the performance of a game using the hardware-acceleration capabilities offered by Silverlight 3..

Time for action enabling hardware acceleration A good gam applet QR Code ISO/IEC18004 e must run offering smooth animation and good-looking graphics on the screen. Let"s assume you have some doubts about the performance offered by Silverlight 3. Therefore, you decide to make some changes to the application developed in the previous chapter in order to test hardware acceleration.

Hence, you will be able to develop games exploiting some of the features offered by modern GPUs in Silverlight. Now, we are going to show more ghosts moving on the screen, but this time doing some transformations and using some hardware acceleration:. We need a computer with a GPU or accelerated graphics card compatible with DirectX 9.0c installed in order to achieve significant results for the next experience..

Stay in th e SilverlightMonster project. Open the ASPX code for SilverlightMonsterTestPage.aspx (by doubleclicking on it in the Solution Explorer, found under the SilverlightMonster.

Web project). This is the ASPX test page for the project that creates the Silverlight control host, which runs the generated Silverlight application (the .xap file).

Find the section beginning with the following line of code:. <object Quick Response Code for Java data="data:application/x-silverlight-2,". 3. 4..

In this pr QR for Java oject, the first two complete lines are the following:. <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="ClientBin/SilverlightMonster.xap"/>. [ 44 ]. 2 . Insert the tomcat qr bidimensional barcode following line of code after the line that begins with <param name="source". (We are setting the EnableGPUAcceleration boolean parameter to true for the Silverlight plugin instance.).

<param name="EnableGPUAcceleration" value="true" /> The last p javabean QR Code JIS X 0510 art of the ASPX code that creates the Silverlight control host will be similar to the following screenshot:. What just happened We changed jboss qr codes a parameter that enabled GPU acceleration for some operations in the Silverlight host control. However, that is not enough to guarantee that Silverlight will use the GPU. We have to make some additional changes to the user interface elements (UI elements) shown by the application, and we have to perform the operations that benefit from hardware acceleration.

. Time for action transforming media using the GPU We are goi spring framework qr-codes ng to make some changes to the application. This time, we will show eight ghosts. We will configure some additional parameters to allow hardware acceleration for some operations and we will scale, rotate, and translate them.

At the same time, we will be changing their opacity settings:. 1. 2..

Stay in th QRCode for Java e SilverlightMonster project. Open the XAML code for Ghost.xaml.

Remove only the following two lines that define a Grid named LayoutRoot as we want the illustration to be a part of a Canvas instead of a Grid:. <Grid x :Name="LayoutRoot"> </Grid> [ 45 ]. Working with 2D Characters 3. 4..

Change the Java QR Code ISO/IEC18004 name of the main Canvas from "Layer_3" to "LayoutRoot" (the default value for the root element). Add the following lines after the first line that begins with the definition of the main Canvas. (We are assigning the BitmapCache value to the CacheMode property of the Canvas that contains the ghost"s paths.
