2016-03-16OPENGL: Move pipeline code to pipelines/.Johannes Schickel
2016-03-16OPENGL: Only allow Pipeline to switch active Framebuffers.Johannes Schickel
2016-03-16OPENGL: Do not allow direct access to Context::activePipeline.Johannes Schickel
2016-03-16OPENGL: Implement texture drawing in Pipeline instead of Surface.Johannes Schickel
2016-03-16OPENGL: Make shader/framebuffer part of pipeline state.Johannes Schickel
2016-03-16OPENGL: Don't prefix maxTextureSize variable for consistency.Johannes Schickel
2016-03-16OPENGL: Introduce abstraction for framebuffer.Johannes Schickel
This allows us to use various framebuffer settings easily. Now the GPU accelerated CLUT8 surface implementation does not need to query former framebuffer state anymore.
2016-03-16OPENGL: Introduce ShaderManager to handle builtin shaders.Johannes Schickel
2016-03-16OPENGL: Introduce pipeline abstraction to cleanup code.Johannes Schickel
2016-03-16OPENGL: Support GLSL based CLUT8 look up for GLES2+.Johannes Schickel
2016-03-16OPENGL: Detect NPOT support for GLES.Johannes Schickel
For GLES1+ there exists GL_OES_texture_npot, which indicates that there is NPOT support. GLES2 always had (limited) NPOT support, which is all we require, thus we always enable it.
2016-03-16OPENGL: Simplify shader support checks.Johannes Schickel
2016-03-16OPENGL: Keep feature state for all contexts and log them.Johannes Schickel
2016-03-16OPENGL: Handle GLES2 and GL shaders uniformly.Johannes Schickel
GLES2 requires precision qualifiers to be set and allows use of precision qualifiers. For GLES2 we define a default precision now. Since precision qualifiers are not supported in the GLSL version we use for GL, we introduce compatibility #defines.
2016-03-16OPENGL: Accelerate palette lookups with shaders.Johannes Schickel
This currently is limited to GL contexts.
2016-03-16OPENGL: Introduce simple abstraction for surfaces.Johannes Schickel
This is basically an interface extracted from Texture without any knowledge about any actual implementation, except for copyRectToTexture, fill, and dirty rect handling. These are convenient helpers.
2016-03-16OPENGL: Cleanup. Remove Texture::getHardwareFormat.Johannes Schickel
2016-03-16OPENGL: Move color key handling for CLUT8 to TextureCLUT8.Johannes Schickel
2016-03-16OPENGL: Fix texture format for BGR565.Johannes Schickel
2016-03-16OPENGL: Move max texture size information to Context.Johannes Schickel
2016-03-16OPENGL: Create new abstraction for GL texture objects.Johannes Schickel
2016-03-16OPENGL: Remove (some) unused GL definitions.Johannes Schickel
2016-03-16OPENGLSDL: Request "standard" GL contexts.Johannes Schickel
Compatibility profiles only exist in modern OpenGL and we request an ancient version.
2016-03-16OPENGL: Unify shader implementation for GL and GLES2.Johannes Schickel
2016-03-16OPENGL: Slightly cleanup programmable pipeline handling.Johannes Schickel
2016-03-16OPENGL: (Partly) move context specific handling to Context.Johannes Schickel
This does not include (most) shader setup, and projection matrices yet.
2016-03-16OPENGL: Make Context::reset explicitly reset state.Johannes Schickel
2016-03-16OPENGL: Slight simplifcation for opengl-func.h usage.Johannes Schickel
2016-03-16OPENGLSDL: Destroy GL context on exit with SDL2.Johannes Schickel
2016-03-16OPENGL: Handle destruction gracefully when no context is setup.Johannes Schickel
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
2016-03-16OPENGLSDL: Slight cleanup.Johannes Schickel
2016-03-16OPENGL: Simplify context type setting.Johannes Schickel
2016-03-16OPENGLSDL: Try to use GL(ES) context SDL2 defaults to.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
2016-03-09SDL: Fix compilation with SDL2 and MSVC2015.Johannes Schickel
2016-03-09GCW0: Remove hardcoded list of skipped engines.Eugene Sandulenko
Now we rely on highres feature of the backends
2016-03-05GCW0: Disabled more 640x480-only enginesEugene Sandulenko
