---------------------------------

2009-11-17 the_fiddler
|
||||
|
||||
* Removed unused code.
|
||||
* Fixed OnUpdateFrame timing calculation (the previous
|
||||
implementation could overshoot the target by up to 50%).
|
||||
Refactored Update-/RenderFrame dispatching into a separate
|
||||
method.
|
||||
* Updated release notes for 1.0 beta-2 release.
|
||||
* Bumped version numbers for 1.0 beta-2 release.
|
||||
* Added VertexAttribPointer(..., int) and DrawElements(..., int)
|
||||
overloads.
|
||||
* Fixed NormalPointer and FogCoordPointer parameters. Added missing
|
||||
TexCoordPointer(..., int) overload. Added DrawElements(..., int)
|
||||
overload. Renamed the last parameter from pointer to offset, to
|
||||
clarify its intent. (Fixes isse [#1386]: "Add overloads for
|
||||
TexCoordPointer and NormalPointer".)
|
||||
* Completely disabled CL10, ES10 and ES11 wrappers. They won't be
|
||||
in the 1.0 release, we can reduce download size a bit.
|
||||
* Type, Parameter, ParameterCollection and Function classes now
|
||||
implement IComparable directly (rather than casting to strings
|
||||
and comparing those). Modified comparison order to place pointer
|
||||
overloads after reference or array overloads. Fixes issue
|
||||
[#1098]: "[Bind] Work around VS bug by ensuring pointer
|
||||
parameters are generated last".
|
||||
|
||||
2009-11-16 the_fiddler
|
||||
|
||||
* Added strongly-typed tokens for GetActiveUniformBlock, which was
|
||||
introduced in OpenGL 3.1. Fixes issue [#1216]: "[GL]
|
||||
GetActiveUniformBlock* methods take ArbUniformBufferObject
|
||||
parameters".
|
||||
* Added new OpenGL 3.1 tokens for ARB_texture_rectangle,
|
||||
ARB_shader_objects and EXT_gpu_shader4. Fixes issue [#1355]:
|
||||
"TextureRectangle tokens for ActiveUniformType".
|
||||
* VertexAttribIPointer should take the integer subset
|
||||
(VertexAttribIPointerType) of VertexAttribPointerType. Fixes
|
||||
issue [#1166]: "VertexAttribIPointer pointer type parameter".
|
||||
* Removed invalid BGRA token from VertexAttribPointerType.
|
||||
* Made unix kernel detection less strict. The program is now
|
||||
allowed to run even the specific kernel name is unknown. Partly
|
||||
fixes issue [#1382]: "OpenTK and other Unix OS".
|
||||
* Added new OpenGL 3.x tokens to GenerateMipmap. Fixes issue
|
||||
[#1162]: "GL.GenerateMipmap argument".
|
||||
* Vector3(d).Cross: do not modify 'result' more than once to ensure
|
||||
that Cross(ref a, ref b, out a) works correctly. Optimized
|
||||
vector-quaternion transform. Fixes issue [#1373]: "[Math]
|
||||
optimize Vector transform by Quaternion".
|
||||
* Changed vector-quaternion transformations to use standard q * v *
|
||||
q^-1 convention. Fixes issue [#1372]: "[Math] Vector
|
||||
transformation by Quaternion follows non-standard quaternion math
|
||||
convention".
|
||||
* Added support for fractional mouse wheel values. Fixes issue
|
||||
[#1279]: "Mouse wheel does not seem to work".
|
||||
* Renamed "Entry" to "Unmanaged Name" to clarify its purpose.
|
||||
* Make context current on loading thread and be more defensive when
|
||||
retrieving unmanaged entry points. Resolves issue [#1378]:
|
||||
"OpenGL Extensions test fails".
|
||||
* Launch samples on a different thread than the launcher. Samples
|
||||
may install their own message loops and some operating systems do
|
||||
not behave correctly with multiple message loops on a single
|
||||
thread.
|
||||
* Preserve the sign of the mouse position. Fixes issue [#1376]:
|
||||
"mouse position".
|
||||
* Fixed InvalidCastException in keyboard logging delegates.
|
||||
|
||||
2009-11-15 kanato
|
||||
|
||||
* MacOS: Fix crash in CheckEnterLeaveEvents if using WinForms too.
|
||||
* MacOS: Correct resizing behavior and correctly implement Bounds,
|
||||
ClientRectangle, and ClientSize getters and setters.
|
||||
* MacOS: Add proper icon support for the dock.
|
||||
* MacOS: Implement Focused property and FocusChanged event.
|
||||
* MacOS: Implement mouse enter / leave events.
|
||||
|
||||
2009-11-14 kanato
|
||||
|
||||
* MacOS: Clean up AglContext destruction code. Implement
|
||||
INativeWindow.Close method.
|
||||
* MacOS: Several minor fixes: * Implement MouseWheel event *
|
||||
Implement KeyPress event * Fix generation of MouseMove events *
|
||||
Fix right mouse button up event
|
||||
* MacOS: Fix bug where application started from the command line
|
||||
would not be in the foreground and not respond to keyboard
|
||||
events.
|

2009-11-12 the_fiddler
|

* Do not hook ProcessExit event if an X server is not available.
|
||||
Should fix issue [#1364]: 1.0 beta-1 throws
|
||||
TypeInitializationException in OpenTK.Platform.X11.API when
|
||||
running on windows. Cleaned up stale comments and code.

|
||||
|

* * Vector4.cs: * Vector3.cs: * Vector2.cs: * Vector4d.cs: *
|
||||
Vector3d.cs: * Vector2d.cs: Removed code using C# 3.0 features.
|
||||
* * BlittableValueType.cs: Clarify how BlittableValueType<T>.Stride
|
||||
works on non-blittable types.
|
||||
* * Source/OpenTK/BlittableValueType.cs: Removed struct constraint.
|
||||
Sometimes consumers of this class may not be able to use struct
|
||||
generic constraints - the class is now usable in this case. *
|
||||
Source/Examples/OpenTK/Test/BlittableValueTypes.cs: Test
|
||||
BlittableValueType class using several different types.

||||
This is the first beta release of OpenTK 1.0. Important changes include:
|
||||
* Type-safe OpenGL|ES 2.0 bindings.
|
||||
* A large number of new examples on picking, shaders, dds textures, constructive solid geometry and multithreading.
|
||||
* Improved Mac OS X support.
|
||||
* Improved multi-monitor support.
|
||||
* Improved multithreading support.
|
||||
* A large number of bug- and stability fixes.
|
||||
* Improved documentation.
|
||||
* Improvements and bugfixes to the build system.
|
||||
* Temporary removal of OpenGL|ES 1.0, 1.1 and OpenCL bindings.
|
||||
This is the second beta release of OpenTK 1.0. This release a laarge number of issues identified in the first beta. Additionally, it:
|
||||
* improves support for Mac OS × (multiple monitors, dock integration, input focus and more).
|
||||
* allows OpenTK to run on *BSD, Solaris and other Unix variants.
|
||||
* fixes a timing issue that caused UpdateFrame events to be raised up to 50% faster than necessary.
|
||||
* adds a number of missing tokens for OpenGL 3.1 and 3.2.
|
||||
* fixes mouse movement on windows and adds support for fractional wheel values (available in high-precision mice).
|
||||
* fixes and optimizes quaternion-vector transforms.
|
||||
* further improves multithreading support on Linux.
|
||||
* works around a Visual Studio bug, which caused a number of OpenGL wrappers to disappear from intellisense.

[Known issues]
|
||||
|
||||
* The Mac OS X port needs testing. If you encounter a bug, please report it at http://www.opentk.com/node/add/project-issue/opentk.
|
||||
|
||||
* OpenGL 3.1 and 3.2 fucntions may be missing specific tokens. Please report any such issues at http://www.opentk.com/node/add/project-issue/opentk
|
||||
|
||||
* Mono 2.2 and 2.4.0 fail to compile OpenTK due to a compiler bug (https://bugzilla.novell.com/show_bug.cgi?id=488960). Please compile with Mono 2.0, 2.4.2+ or use the supplied binaries instead.
|
||||
* The example browser is incomplete.
|
||||
* The Mac OS X port needs work. If you are interested in helping out, please make a post at http://www.opentk.com/forum/3.
|
||||
|
||||
* The example browser is a work-in-progress.
|
||||
|
||||
* MonoDevelop fails to sign assemblies (bugs https://bugzilla.novell.com/show_bug.cgi?id=484752 and https://bugzilla.novell.com/show_bug.cgi?id=537063).
|
||||
* OpenGL 3.2 methods may be missing specific tokens. Please report any such issues at http://www.opentk.com/node/add/project-issue/opentk

[API changes]
|
||||
|
||||
Please note that binary compatibility is not preserved between beta releases.
|
||||
|
||||
If you are upgrading from OpenTK 0.9.9-0 or earlier you can simplify the upgrade process by adding a reference to OpenTK.Compatibility.dll and OpenTK.GLControl.dll (if necessary). OpenTK.Compatibility contains code and APIs that have been deprecated and removed from the core library, as well as code for interoperation with the Tao framework.
|
||||
If you are upgrading from OpenTK 0.9.9-0 or earlier you can simplify the upgrade process by adding a reference to OpenTK.Compatibility.dll and OpenTK.GLControl.dll (if necessary). OpenTK.Compatibility contains code and APIs that have been deprecated and removed from the core library and supports applications written against the Tao framework (Tao.OpenGl, Tao.OpenAl and Tao.Platform.Windows.SimpleOpenGlControl).

||||
|
||||
|
||||
[1.0 beta-2]
|
||||
|
||||
1. NormalPointer(..., int) and FogCoordPointer(..., int) overloads no longer specify a 'size' argument.
|
||||
Solution: this is the correct signature, the 'size' argument found in previous OpenTK versions was invalid. This bug is unlikely to appear in practice.
