2016-03-16OPENGL: Add support for shaders with GL contexts.Johannes Schickel
2016-03-16OPENGL: Reset context description on context destroy.Johannes Schickel
2016-03-16OPENGL: Reset full context structure.Johannes Schickel
2016-03-16OPENGL: Support GLES2 contexts.Johannes Schickel
2016-03-16OPENGL: Typo.Johannes Schickel
2016-03-16OPENGL: Simplify orthogonal projection setup.Johannes Schickel
2016-03-16OPENGL: Simplify context type setting.Johannes Schickel
2016-03-16OPENGL: Support RGB555 for OpenGL ES output.Johannes Schickel
This mode should *not* be used by any new engines/code. If someone is going to use it and says it works with the OpenGL output, please make them wear a red uniform and beam them onto a remote planet.
2016-03-16OPENGL: Allow runtime specification of OpenGL mode.Johannes Schickel
Formerly, we required that the OpenGL mode was fixed at compile time. Now we allow the code to work with whatever it is given at runtime. It is still possible to force a context type on compile time.
2016-03-16OPENGL: Remove support for ARGB8888.Johannes Schickel
This used to be used by Sword25. Since it is not supported by GLES and no engine code uses it we drop support. Hopefully, this helps people to realize they should not use that format in their engine.
2016-03-16OPENGL: Rename GLCALL to GL_CALL.Johannes Schickel
2016-03-16OPENGL: Resolve OpenGL functions on run-time.Johannes Schickel
Formerly we relied on static linkage. However, in the presense of modern OpenGL (ES) implementations it is not easily identifable which library to link against. For example, on Linux amd64 with nVidia drivers and SDL2 setup to create a GLES 1.1 context one would need to link against libGL.so. However, traditionally GLES 1.1 required to link against libGLESv1_CM.so. To prevent a huge mess we simply resolve the OpenGL functions on run-time now and stop linking against a static library (in most cases). GLES support needs to be enabled manually on configure time for now. Tizen changes have NOT been tested.
2016-03-16OPENGL: Define GLCALL in opengl-sys.h.Johannes Schickel
debug.h is now always included and all calls should be made through GLCALL.
2016-03-16OPENGL: Add functionality to query OpenGL functions on runtime.Johannes Schickel
This can and will be used for future extension usage support. Tizen changes have been untested.
2016-03-16OPENGL: Refactor GL extension handling slightly.Johannes Schickel
2015-12-14OPENGL: Smooth mouse experience when black bars are visible.Johannes Schickel
This gets rid of the feeling of the mouse sticking to black borders by using the full output resolution as area for tracking game mouse movement. The same behavior is present in plain SDL output with SDL2.
2015-12-13OPENGL: Limit scissor override to invisible overlay.Johannes Schickel
This fixes some corner cases which caused black bars to appear for a few screen updates when the overlay is visible.
2015-12-12OPENGL: Implement black borders using scissor test.Johannes Schickel
2015-12-12OPENGL: Only redraw screen when actual changes happened.Johannes Schickel
2015-12-12OPENGL: Refactor screen refresh handling.Johannes Schickel
Subclasses of OpenGLGraphicsManager are now supposed to supply a refreshScreen function which handles actual screen updating (for example, buffer swapping).
2015-12-12OPENGL: Fix include guard name.Johannes Schickel
2015-01-07OPENGL: Fix truncation issue resulting in wrong mouse coordinates.Johannes Schickel
2015-01-07OPENGL: Limit mouse cursor drawing to inside game screen when no overlay is ↵Johannes Schickel
visible.
2014-10-28BACKENDS: Remove trailing whitespaceFilippos Karapetis
2014-08-29BACKENDS: Fix some Doxygen comments that seem wrong.Einar Johan Trøan Sømåen
2014-02-25OPENGL: Fix building with --disable-16bitTorbjörn Andersson
2014-02-12OPENGL: Always support RGBA8888 (memory layout).Johannes Schickel
2014-02-12OPENGL: Move RGBA8888 (logical layout) to OpenGL specific formats.Johannes Schickel
The reason here is that GL_UNSIGNED_INT_8_8_8_8 is not supported by the GLES standard. Thus we cannot use it outside OpenGL specific code paths.
2014-02-12OPENGL: Use frac_t for cursor scaling.Johannes Schickel
2014-02-12OPENGL: Simplify shake offset application.Johannes Schickel
2014-02-12OPENGL: Use GLfloat for draw cooridnates in Texture.Johannes Schickel
2014-02-12OPENGL: Use signed types for mouse coordinates.Johannes Schickel
This adjusts for the fact that our event handling also uses signed coordinates.
2014-02-12OPENGL: Properly use signed types for cursor hotspot.Johannes Schickel
2014-02-11OPENGL: Fix cursor regression when defaultFormat doesn't have an alpha channel.Johannes Schickel
2014-02-11OPENGL: Properly setup full game palette on video mode change if required.Johannes Schickel
2014-02-11OPENGL: Refactor texture instantiation.Johannes Schickel
2014-02-11OPENGL: Rename notifyContextChange to notifyContextCreate.Johannes Schickel
2014-02-11OPENGL: Add notification function about context destruction.Johannes Schickel
2014-02-11OPENGL: Release old texture name before creating a new one.Johannes Schickel
This prevents any texture name leaks (and thus memory leaks) on recreateInternalTexture calls.
2014-01-23Merge pull request #409 from lordhoto/rttiJohannes Schickel
Enable RTTI and clean up the code by exploiting the availability of dynamic_cast.
2014-01-21OPENGL: Properly query for OpenGL errors.Johannes Schickel
There might be various error flags and we need to clear all of them to get precise error results. Thus, we need to call glGetError in a loop to achieve that.
2013-11-20OPENGL: Fix texture re-allocation checkWillem Jan Palenstijn
This fixes a crash when opening the menu in the SCI Laura Bow 2 intro.
2013-11-17OPENGL: Fix >1Bpp mouse cursors which do not require format conversion.Johannes Schickel
2013-10-24SDL: Let SdlGraphicsManager inherit from GraphicsManager.Johannes Schickel
2013-10-23SDL: Do not require a static graphics mode list in OpenGL and SurfaceSDL.Johannes Schickel
2013-10-19OPENGL/SDL: Add screenshot support.Johannes Schickel
2013-10-19OPENGL: Limit maximum Surface size to maximum texture size.Johannes Schickel
This is mostly aimed at old graphics chips. For example, wjp's old laptop only supports 1024x1024 textures but has a 1280x800 screen. Switching to fullscreen would create a bigger overlay than supported. Now it will get limited to an smaller resolution and then scaled too. Alternatively we could think of tiling surfaces into textures. But then handling scaling would be more complicated since it might result in artifacts on texture tile borders.
2013-10-19TIZEN: Adapt to new OpenGL code.Johannes Schickel
Thanks to Chris Warren-Smith for testing this a bit.
2013-10-19OPENGL: Implement dirty rect handling.Johannes Schickel
