* Release program when returning from QOpenGLTextureBlitter::create()Laszlo Agocs2019-06-191-0/+3

* Add an OpenGL program binary disk cacheLaszlo Agocs2016-11-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a glProgramBinary-based disk cache in QOpenGLShaderProgram. By switching the typical program->addShaderFromSourceCode(QOpenGLShader::Vertex, ...) program->addShaderFromSourceCode(QOpenGLShader::Fragment, ...) invocations to program->addCacheableShaderFromSourceCode(QOpenGLShader::Vertex, ...) program->addCacheableShaderFromSourceCode(QOpenGLShader::Fragment, ...) the compilation may be skipped via gl(Get)ProgramBinary and a disk cache, when supported. Such QOpenGLShaderProgram instances will have no QOpenGLShader instances attached. Instead, the entire program binary (which is driver-specific) is loaded as-is. Support means OpenGL ES 3.0 or the presence of GL_ARB_get_program_binary, in combination with >= 1 supported binary formats. Note that some drivers claim program binary support but expose no formats. This amounts to no support in practice. When support is not present, calling the new functions is equivalent to the non-cacheable variants. If the OpenGL driver changes (vendor, renderer, version strings), recompilation and storage of the new, potentially incompatible binary program will happen transparently. The cache can always be disabled by setting QT_DISABLE_SHADER_DISK_CACHE=1 or the new application attribute Qt::AA_DisableShaderDiskCache. Location-wise the primary choice is the shared cache (GenericCacheLocation). If this is not available or is not writable, the per-process one (CacheLocation) is used instead. In addition to the new public APIs in QOpenGLShaderProgram, the main shader users in QtGui are migrated as well. (OpenGL paint engine, glyph cache, blitter, eglfs mouse cursor). This means that any application using QPainter on OpenGL or widgets with eglfs will benefit from the improved startup times. Qt Quick will follow suit as well. [ChangeLog][QtGui][OpenGL] QOpenGLShaderProgram offers a built-in program binary disk cache for systems with OpenGL ES 3.x or GL_ARB_get_program_binary. This can lead to significant increases in performance when it comes to application startup times for example. Usage is opt-in for direct C++ users of the class, however Qt's own main users of shaders, including Qt Quick and QPainter's OpenGL engine, are migrated to use the new, cache-enabled APIs. Opting out on application level is always possible via Qt::AA_DisableShaderDiskCache.

* Make QOpenGLTextureBlitter publicLaszlo Agocs2016-07-291-2/+191
| | | | | | | | | | | | Change QOpenGLTextureBlitter to be a public API, as it was originally intended. There are now significant external uses outside qtbase (C++ compositor examples in QtWayland), and the API is considered proven enough. [ChangeLog][QtGui] QOpenGLTextureBlitter, a utility class to draw textured quads, has been made public.

* QOpenGLTextureBlitter: Remove Origin location for the Target rectJørgen Lind2014-02-161-13/+11
| | | | | | | | | | | | | | | | | | | | | The Origin for Target rect was deemed a confusing concept. The current implementation would translate the target rect to the coordinate system specified. However, the order and "direction" of the vertices would always be the same. So drawing a texture in for one target rect defined in one coordinate system would paint the texture the same way as it would when a texture was drawn for a target rect drawn in the "opposite" coordinate system. The point with this was that if you wanted to "flip" the texture you would specify that with the source coordinate system. However, this approach breaks on different levels, such as QRect has functions which expects a top left coordinate system (ie. top() and bottom()). In the end Qt uses a top left coordinate system, hence QWindow specifies a top left coordinate system, and hence the api becomes easier if it is not possible to define the coordinate system of the target viewport.

* QOpenGLTextureBlitterJorgen Lind2014-02-101-0/+394
private api, but useful for 2d gui code that suddenly finds itself needing to get a set of textures onto some fbo I didn't want to include ARB_copy_image since it looks like its from texture/renderbuffer -> texture/renderbuffer while this class implies texture -> write fbo. We could wrap ARB_copy_image in QOpenGLTexture or some other class or we can add it later. I have not added any QOpenGLTexture functions since this class opperates on the GLuint identifier. We can add overloads later. Change-Id: I3e565b33466c1c183a249a33c3e82c6786debd55 Reviewed-by: Paul Olav Tvete <paul.tvete@digia.com>
