Stefanos A. 0a46e20029 Added WGL_DRAW_TO_WINDOW_ARB flag
Without this flag, OpenGL rendering does not work as expected.

Additionally, all WGL_ARB_pixel_format attributes are expected to be
specified in key-value pairs. Fixed double-buffering and stereoscoping
rendering attributes.

Stefanos A. a2744719d5 Improved WGL mode selection
Fixed WGL_ARB_pixel_format attribute selection for doublebuffering,
stereoscopic rendering and hardware acceleration. Implemented
minimization strategy to select the optimal PixelFormatDescriptor in the
fallback path.

Stefanos A. 956bbe6491 Fixed DescribePixelFormatPFD
When using the PFD codepath, we now call DescribePixelFormat to retrieve
an exact interpretation of the pixel format selected by the driver.

Stefanos A. 1723be8a8b Prioritize accelerated formats first
Instead of creating a list of all available formats and iterating
through that, we let the driver decide which is the best accelerated
format to use for the user parameters. If no such format exists, we fall
back to generic acceleration or software acceleration, in turn.

This affects issue #21

Stefanos A. a57b4c4270 Fixed GetModesARB implementation
The correct way to query number of available pixel formats is to use
Wgl.Arb.GetPixelFormatAttrib(NumberPixelFormatsArb), not
Wgl.Arb.ChoosePixelFormats. This fixes an issue where Intel drivers
would fail to report any pixel formats in GetModesARB, even when
WGL_ARB_pixel_format is supported.

Stefanos A. 44b8a9dbdc Use gdi32 implementations of functions
Several functions are defined in both gdi32 and opengl32. Using the
opengl32/wgl versions did not appear to help with issue #19. Let's use
the gdi32 version instead, as suggested here:

Stefanos A. f4f793a5d3 Minor code cleanup
No need to wrap Wgl.DescribePixelFormat, just call it directly.

Stefanos A. 0a39143b3e Removed unused WGL methods
WGL was autogenerated a few years ago but never touched after that.
Since we use a tiny fraction of all available methods, it makes sense to
remove the unused ones. This reduces dll size and improves startup
times.

Stefanos A. f142dbdfc3 Improved WinGLContext initialization
Cleaned up and added debugging information to the temporary context
construction in WinGLContext. Simplified WinGraphicsMode constructor.

Stefanos A 95316829ec Updated WGL init sequence
WinGraphicsMode no longer creates a temporary context in order to create
the list of available modes. Instead, it requires to be passed an
existing context in its constructor.

WinGLContext now creates one temporary context in its static constructor
and hands that to WinGraphicsMode.

WinFactory no longer supports the CreateGraphicsMode API. This API will
be removed in the future, because the link because contexts and modes
cannot be separated in the general case.

the_fiddler cf4619fe6d Added PFD_SUPPORT_COMPOSITION on Vista and higher, to avoid inadvertently disabling Aero.
Allow non-accelerated formats when all accelerated ones fail. Fixes issue [#2224]: "Getting GraphicsModeException from WinGraphicsMode constructor".
2011-02-09 00:23:43 +00:00
the_fiddler 36913ab2bb Add DrawToWindow and SupportOpenGL flags to GetModesARB and check whether Wgl.Arb.ChoosePixelFormat() worked correctly (to avoid undefined results). 2011-01-18 22:34:06 +00:00
the_fiddler 569c4c86c7 Refactored and simplified DisplayDevice detection (devices are now stored in the platform-specific drivers instead of the frontend).
Made XRR resolution changes more robust.
Resolution changes now refresh the DisplayDevices on Windows.
2010-11-21 20:16:18 +00:00
the_fiddler 294f23f34a Improved and simplified behavior of RelaxParameters. Removed unused code. 2010-11-11 19:32:22 +00:00
the_fiddler cff4ab2d3c Retrieve all pixel formats at once and select the correct one through a custom selection predicate. Simplifies the code significantly and reduces the chance of race conditions. 2010-11-08 19:41:24 +00:00
the_fiddler 2aa1dcef1d Avoid reference to System.Windows.Forms.
Pass a concrete GraphicsMode to the context constructor in SelectPixelFormatARB to avoid NRE.

the_fiddler 88e6aceae0 Synced trunk with 1.0 branch. 2010-10-02 18:52:34 +00:00
the_fiddler b6f1590636 Remove System.Windows.Forms.Control dependency in favor of OpenTK.NativeWindow. 2009-09-08 13:09:50 +00:00
the_fiddler b1b3706e64 Fixed recursion that between WinGraphicsMode.SelectGraphicsModeARB and GraphicsMode.Default.
Fixed acceleration attribute in WinGraphicsMode.SelectGraphicsModeARB. Now, antialiasing works on nvidia drivers, too.

the_fiddler 66efa41a8f WinGraphicsMode now uses wglChoosePixelFormatARB, if available. This allows the use of FSAA modes. 2009-06-01 11:05:31 +00:00
the_fiddler a22019d890 Normalize line endings and set the mime-type=text/plain and eol-style=native properties on all files. 2009-02-22 10:43:35 +00:00
