Compares the quality of several antialiasing techniques.

This sample is written in C++.

Files

  • DeclareDPIAware.manifest: Declares that the application is DPI-aware.
  • MSAARenderingSample.cpp: Contains the application entry point and the implementation of the MSAASampleApp class.
  • MSAARenderingSample.h: The header file for the DemoApp class.
  • MSAARenderingSample.sln: The sample's solution file.
  • MSAARenderingSample.vcproj: The sample project file.
  • RingBuffer.h: The header file for the RingBuffer class. RingBuffer works like a standard array, except that when it fills up, data at the beginning is overwritten.

Prerequisites

  • Microsoft Windows 7
  • Windows Software Development Kit (SDK) for Windows 7 and .NET Framework 3.5 Service Pack 1
  • March 2009 DirectX SDK

Configuring without Visual Studio

  1. Open a Windows SDK command shell.
Bitness Path
32-bit Windows "C:\Program Files\Microsoft DirectX SDK <version>\Utilities\bin\dx_setenv.cmd"
64-bit Windows "C:\Program Files (x86)\Microsoft DirectX SDK <version>\Utilities\bin\dx_setenv.cmd"

Type the command line above, adjusting the path as necessary depending on where you installed the DirectX SDK. For example,

"C:\Program Files (x86)\Microsoft DirectX SDK (March 2009)\Utilities\bin\dx_setenv.cmd"

You must perform this step each type you compile the sample.

  1. To compile the sample, type vcbuild /u Interactive3dTextSample.sln.

Configuring for Visual Studio (preferred method)

After installing the DirectX SDK, you must configure Visual Studio to use the executables and include files provided by the DirectX SDK. You must configure Visual Studio for each platform (Win32 or x64) you want to build against.

For building against the Win32 (x86) platform:

  1. Launch Visual Studio 2008.

  2. Open the Tools menu and select Options. The Options dialog box appears.

  3. In the left pane of the Options dialog box, expand the Projects and Solutions node.

  4. Under Project and Solutions, select VC++ Directories.

  5. In the right pane, set the "Platform" drop-down list box to Win32 and the "Show directories for" drop-down list box to Executable files.

  6. At the bottom of the list of executable file directories, create a new entry for the DirectX SDK:

Bitness Path
32-bit Windows C:\Program Files\Microsoft DirectX SDK <version>\Utilities\bin\x86
64-bit Windows C:\Program Files (x86)\Microsoft DirectX SDK <version>\Utilities\bin\x86

(If there was already such an entry, move it to the bottom of the list.)

  1. Set the "Show directories for" drop-down list box to "Include" files.

  2. At the bottom of the list of directories, create a new entry for the DirectX SDK:

Bitness Path
32-bit Windows C:\Program Files\Microsoft DirectX SDK <version>\Include
64-bit Windows C:\Program Files (x86)\Microsoft DirectX SDK <version>\Include

If there was already such an entry, move it to the bottom of the list.

  1. Set the "Show directories for" drop-down list box to "Library" files.

  2. At the bottom of the list of directories, create a new entry for the DirectX SDK:

Bitness Path
32-bit Windows C:\Program Files\Microsoft DirectX SDK <version>\Lib\x86
64-bit Windows C:\Program Files (x86)\Microsoft DirectX SDK <version>\Lib\x86

If there was already such an entry, move it to the bottom of the list.

  1. Click OK.

For building against the x64 platform:

  1. Launch Visual Studio 2008.

  2. Open the Tools menu and select Options. The Options dialog box appears.

  3. In the left pane of the Options dialog box, expand the Projects and Solutions node.

  4. Under Project and Solutions, select VC++ Directories.

  5. In the right pane, set the "Platform" drop-down list box to x64 and the "Show directories for" drop-down list box to Executable files.

  6. At the bottom of the list of executable file directories, create a new entry for the DirectX SDK:

Bitness Path
32-bit Windows C:\Program Files\Microsoft DirectX SDK <version>\Utilities\bin\x86
64-bit Windows C:\Program Files (x86)\Microsoft DirectX SDK <version>\Utilities\bin\x64

If there was already such an entry, move it to the bottom of the list.

  1. Set the "Show directories for" drop-down list box to "Include" files.

  2. At the bottom of the list of directories, create a new entry for the DirectX SDK:

Bitness Path
32-bit Windows C:\Program Files\Microsoft DirectX SDK <version>\Include
64-bit Windows C:\Program Files (x86)\Microsoft DirectX SDK <version>\Include

If there was already such an entry, move it to the bottom of the list.

  1. Set the "Show directories for" drop-down list box to "Library" files.

  2. At the bottom of the list of directories, create a new entry for the DirectX SDK:

Bitness Path
32-bit Windows C:\Program Files\Microsoft DirectX SDK <version>\Lib\x64
64-bit Windows C:\Program Files (x86)\Microsoft DirectX SDK <version>\Lib\x64

If there was already such an entry, move it to the bottom of the list.

  1. Click OK.

Building the Sample

To build the sample using the command prompt:

  1. Open a Windows SDK command shell and run the dx_setenv.cmd command (see the Configuring without Visual Studio section for more information.)
  2. Navigate to the sample directory.
  3. Type vcbuild /u MSAARenderingSample.sln

To build the sample using Visual Studio 2008 (preferred method):

  1. Open Windows Explorer and navigate to the sample directory.
  2. Double-click the icon for the .sln (solution) file to open the file in Visual Studio.
  3. In the Build menu, select Build Solution. The application will be built in the default \Debug or \Release directory.

Running the Sample

  • 'Left/Right' arrow keys: Switch among the Aliased, MSAA, or PPAA anti-aliasing modes.
  • Spacebar: Starts or pauses scene animation.
  • Up Arrow: Increases the number of primitives rendered
  • Down Arrow: Decreases the number of primitives rendered.
  • Mouse Wheel: Zooms in and out over a region.
  • "A" key: Switches between anti-aliasing modes.
  • "W" key: Switches between solid and wireframe scenes.
  • "L" key: Turns off the zoom window
