IBind implementations must now store explicit references to Settings,
GLTypes and CSTypes instances. This allows us to use multiple
configurations in the same process.
FuncProcessor now implements all translation logic for types, parameters
and functions. This used to be scattered in the various classes (Type,
Parameter, etc) resulting in a rather disgusting spaghetti. Code
generation has been removed from FuncProcessor and is now handled by the
various language-specific ISpecWriter backends.
This is part of a long-due series of source cleanup patches. ToString()
is no longer used for code generation (code generation is handled by an
ISpecWriter instance.) Enum is no longer public. EnumCollection now
exposes its backing store through an interface, rather than a concrete
class (simpler to change backing store in the future.)
This is part of a long-due series of source cleanup patches. ToString()
is no longer used for code generation (this is handled by an ISpecWriter
implementation). This class is no longer public.
This is part of a long-due series of source cleanup patches. All
translation logic is now part of FuncProcessor. Code generation is now
handled by an ISpecWriter implementation. Minor improvements to
IEquatable and ToString() implementations. Reduced the surface of the
public API.
This is part of a long-due cleanup patch series. All translation logic
is now part of the FuncProcessor. Language-specific code generation is
now part of the ISpecWriter, not the delegate class. Implemented the
IEquatable interface.
This is part of a long-due source cleanup series. All Translate*()
methods are now part of the FuncProcessor. Additionally, ToString() has
been improved and the IEquatable interface is now implemented.
ParameterCollection now has better control of when its cache should be
rebuilt.
This is part of a long-due source cleanup operation. GLTypes and CSTypes
are no longer global singletons, but must now be accessed through an
IBind instance. All Translate*() methods are now part of the
FuncProcessor. ToString() has been improved and the IEquatable interface
is now explicitly implemented.
Settings, GLTypes and CSTypes are no longer global singletons. Instead,
explicit instances must be stored in the IBind implementation. This
allows us to use multiple configurations in the same process.
Utilities.Keywords now accepts an explicit parameter, instead of
accessing Settings directly. This allows us to use multiple
configurations in the same process.
Additionally, the Utilities class is no longer public (the Bind project
is not meant to be consumed as a dll.)
A Settings object is now passed directly as a parameter, in order to
support different configurations in the same process. The XmlSpecReader
can now distinguish between, and support both, pre-GL4.4 and post-GL4.4
specs.
Deprecated elements are marked as such in the compatibility profile and
are completely absent from the core profile. This is in-line with the
new glcore headers from Khronos.
A function redefinition usually stems from a bug in the OpenGL specs, or
a bug in the spec converter. The binding generator now logs a warning,
instead of crashing, when a redefinition is encountered.
Use a stable sort for generated elements, in order to make the generated
file work better with version control. Extension names are now extracted
directly from function names - solves issues with functions that are
defined in multiple extensions.
GL4.4 renamed PixelInternalFormat to InternalFormat. The missing tokens
are now re-added, since a lot of functions depend on them. Additionally,
a number of 'open' <use> elements now define a specific enum reference.
This is not necessary, but is good for documentation purposes.
Instead of recursing, we use a simple do..while loop to resolve the
transitive reference of a constant. If there is a loop at any point, we
stop and use a brute force search over all tokens. If this still fails
to resolve the reference, then we report this reference as unresolved.
Function overrides are now looked up in the following order: specific
name (e.g. ProgramParameteriARB), extensionless name (e.g.
ProgramParameteri) and generic mame (e.g. ProgramParameter). This
improves the override resolution for functions with multiple extension
forms (core, ext, arb, etc).
An EnumProcessor or FuncProcessor instance is now required in order to
call their Translate*() methods. A number of transformations that
relied on calling the static methods have now been moved inside the
processor classes.
Instead of hardcoding a list of extensions, extensions are now read
directly from the signatures.xml file. Acronyms for new texture
formats are now listed.
Instead of using a hardcoded list of extensions, the parser will now
use a regex to detect extension names. This gives better results on
new specs without manual editing.
ShaderSource is supposed to accept an array of string lengths as the
last parameter. The count="1" statement in the registry is wrong.
GL.VertexArrayFogCoordOffsetEXT is supposed to receive a
FogPointerType.
For instance, if we override both ClearBufferfi and ClearBuffer, then
ClearBuffer{i f ui}v will be overriden be ClearBuffer and
ClearBufferfi will be overriden by ClearBufferfi. This allows us to
specialize overrides when necessary.
uint-to-intptr conversion must obey uint-to-int conversions on 32-bit
machines, otherwise an OverflowException may occur: conversions of
numbers over 2^31-1 must be declared as unchecked.
Fixes issue reported here: http://www.opentk.com/node/3418
SDL_GL_GetDrawableSize was introduced after 2.0.0, so we need to check for that version before we call this method. Fixes MethodNotFounException on vanilla libsdl2-2.0.0 on linux.
The debug.log would be deleted after launching an example, causing the
example browser to complain that the file cannot be found. In reality,
it should be deleted before launching an example - fixed.
When HiDPI is enabled, the size of the OpenGL surface (specified in
pixels) may no longer correspond to the size of the window (specified
in points). Width, Height, ClientSize and ClientRectangle return the
size of the OpenGL surface in device-dependent pixel coordinates
(origin: top-left pixel of the surface). Bounds and Size return the
size of the window in device-independent point coordinates (origin:
desktop).
This significantly improves the usability of keyboard input, by allowing
a common input scheme to be used on different keyboard layouts. Text
input will be facilitated through a new API.
The support burden for Windows versions prior to XP was too large, plus
the relevant code was completely untested. Removing that will allow us
to focus on the things that really matter.
Starting with OpenGL 4.1 and the ARB_ES2_compatibility extension, desktop contexts can execute OpenGL|ES code. This fallback will allow platforms to execute OpenGL|ES code even if EGL is not available (e.g. Nvidia/Windows).
Some drivers / operating systems export ES entry points as extensions on regular "desktop" GraphicsContexts. Attempt to load them even if the user has not explicitly asked for an ES context.
If SDL2 is supported, the PlatformFactory will now use it for creating the OpenGL ES context. Previously, it would revert to the native drivers when GraphicsContextFlag.Embedded was specified.
MouseMove no longer leaves the window borders when the cursor is
invisible. MouseButtonUp events are now reported even when they occur
outside the window. This aligns SDL2 behavior with the native drivers.
SDL_GL_MakeCurrent(IntPtr.Zero, IntPtr.Zero) is the correct way to
remove the current OpenGL context from the calling thread. Fixes
threaded rendering on Windows.
Using a separate, isolated process protects against incompatible interactions between the Example Browser (WinForms) and the executing example (native or SDL). It also protects the main GUI from crashes in the example code.
Git commit hashcodes are not compatible with the 16bit integer values found in .Net version numbers. Use the git commit count as a version number instead.
Added IDisposable interface to all classes holding native data that must be freed. OpenTK.Toolkit.Init() now returns an IDisposable instance that can be used to cleanup all native data held by OpenTK. This is useful when re-initializing OpenTK (possibly in a new AppDomain), as is the case in the Example browser.
SDL2 will refuse to create an OpenGL context on a window with the SDL_WINDOW_FOREIGN flag (i.e. windows that are passed to SDL2 through SDL_CreateWindowFrom). This must be fixed upstream.
