New in SlimDX March 2011 (Jun 17, 2011)

  • The March 2011 release of SlimDX was a bug fixing and stability release. In this release we diverged from the usual practice of synchronizing our schedule with that of the DirectX SDK, mostly due to the long wait since the previous release, June 2010.
  • March 2011 boasts several bug fixes, some performance improvements, a few bits of missing functionality, and a couple new samples, and we decided that we couldn't wait any longer for the release.

New in SlimDX August 2009 (Jan 5, 2010)

  • This is a major release in terms of new functionality, mainly due to the long-awaited inclusion of Windows 7 support. The new Windows 7 features include Direct3D 11, Direct2D, and DirectWrite.

New in SlimDX March 2009 SP1 (May 9, 2009)

  • The March 2009 release is a major release in terms of new functionality and improvements behind the scenes. Many missing corners were filled in, and several usability enhancements were made across the library on top of the standard array of bug fixes. A new DLL containing beta-level technologies, such as Direct2D and Direct3D11, was added to showcase developing APIs. These APIs will be moved into the core SlimDX DLL once they are given a full release by Microsoft. Until then, they should be viewed as previews, and should not be used for products that expect stable behavior.
  • Performance is another issue focused on in the March release. After extensive testing, several improvements were made to the error handling infrastructure, which showed significant performance increases across the entire library. On top of this, performance issues in the math library were discovered and subsequently eliminated. This involved modifying the types to use fields instead of properties, as value type getters are inlined in .NET prior to version 3.5. These small changes could have a substantial impact on your application simply by recompiling with the new DLL.
  • The following is a list of changes that were made to SlimDX for the March 2009 release.
  • General
  • Added a second DLL, SlimDX.Windows7.dll, to the project to allow for the implementation of beta APIs, such as DX11 and Direct2D.
  • Refactored the handling of COM objects to allow SlimDX to correctly handle certain types / usage scenarios; in particular those having to do with implicitly created objects, such as a D3D9 device s render target, without requiring the user to Dispose() of those objects manually, which violates the Dispose() idiom). Users who were previously using the manual Dispose() workaround will need to remove that workaround, as it will now throw an exception indicating that implicit and ancillary objects should not be Dispose() d.
  • Improved the performance of the internal error checking mechanism.
  • Result watches can no longer be set on success results.
  • Fixed a bug that caused an ObjectDisposedException to be thrown whenever a constructor for an object failed.
  • Design
  • Fixed an off-by-one bug in Color3Converter and Color4Converter.
  • Samples
  • Added a SkinnedMesh sample.
  • Added a simple Direct2D sample.
  • Added a simple text DirectWrite sample.
  • Added a multiformatted text DirectWrite sample.
  • The EnableVSync option in the SampleFramework wasn t being respected in D3D10 mode. That has been fixed.
  • Math
  • Changed all math types to use fields instead of properties. This has been shown to give a substantial performance improvement.
  • Modified the type converters so that math types will still work correctly in PropertyGrid.
  • Added a Rows[([(Int32])]) property and a Columns[([(Int32])]) property to get and set the rows and columns of a matrix.
  • Added array overloads for several math functions, notably Multiply(Matrix*, Matrix*, Matrix*, Int32).
  • Some quick testing shows that for 5 or more matrices, the array multiply is 30% faster per matrix than doing them one at a time.
  • Added a ToArray()()() method to Matrix.
