* openglunderqml example: remove unnecessary resetOpenGLState callLaszlo Agocs2020-06-111-4/+0
| | | | | | | | | | | | | | | Also request the OpenGL RHI backend explicitly, like all the other similar examples (d3d11underqml, and so on) do. Calling resetOpenGLState() in this example is pointless because it happens before returning from the custom rendering function, and the endExternalCommands() call achieves the same internally, i.e. the rhi will know that cached state cannot be used anymore. There are other valid uses cases for resetOpenGLState() but this example does not have those.

* Quick: Don't qualify OpenGL includesUlf Hermann2020-01-271-2/+2
| | | | | | | | | | | | | The headers are moving from QtGui to QtOpenGL. By avoiding the qualification we can keep them compiling either way. Also, add opengl-private to make the types available. Also removed the QGraphicsRotation hack to get access to the projected rotation function of QMatrix4x4. The function is public now.

* Make openglunderqml functional with and without the rhiLaszlo Agocs2019-07-041-8/+23
| | | | | | | | | | It has to be written following the new split approach (beforeRendering for resource setup, beforeRenderPassRecording to issue the actual underlay draw calls), but it will then work both with and without QSG_RHI=1.

* Add the graphics api independent scenegraph portLaszlo Agocs2019-07-041-4/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Opt in via environment variables: QSG_RHI=1 -> enable using QRhi instead of GL QSG_RHI_BACKEND -> set to vulkan, metal, d3d11, gl to override the default (the default is d3d11 on Windows, metal on Mac, gl elsewhere) Or force a given rhi backend via the existing QQuickWindow::setSceneGraphBackend(). Otherwise the default behavior is the same as before, the rhi code path is never active by default. -no-opengl builds are supported in the sense that they work and default to the software backend. However, the rhi code path cannot currently be used in such builds, even though QRhi from qtbase is fully functional with Vulkan, D3D, or Metal even when qtbase was configured with -no-opengl. This cannot be utilized by Quick atm due to OpenGL usage being all over the place in the sources corresponding to the default backend, and those host the rhi code path as well. This will be cleaned up hopefully in Qt 6, with the removal all direct OpenGL usage. Other env.vars.: QSG_RHI_DEBUG_LAYER=1 -> enable D3D debug or Vulkan validation layer (assuming the system is set up for this) QSG_RHI_SHADEREFFECT_DEBUG=1 -> print stuff from ShaderEffect QSG_SAMPLES=1,2,4,... -> MSAA sample count (but QSurfaceFormat works too) QT_D3D_ADAPTER_INDEX=0,1,... -> D3D adapter index QT_VK_PHYSICAL_DEVICE_INDEX=0,1,... -> Vulkan physical device index QSG_RHI_UINT32_INDEX=1 -> always use uint index data (both merged/unmerged, convert when needed - with some rhi backends this is implicit) QSG_RENDER_LOOP -> to override the render loop as usual. The default with RHI is threaded for Metal, threaded for Vulkan on Windows, basic for Vulkan on Linux and Android (to be checked later), while the existing rules apply for OpenGL. Not supported when running with QRhi: - particles - compressed atlases (though this is transparent to the apps) - QSGRenderNode - QQuickRenderControl - QQuickFramebufferObject - certain QQuickWindow functionality that depends directly on OpenGL - anisotropic filtering for textures - native text may lack some gamma correction - QSGEngine applicability unclear - some QML profiler logs may be incorrect or irrelevant Change-Id: I7822e99ad79e342e4166275da6e9e66498d76521 Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* use nullptr consistently (clang-tidy)Shawn Rutledge2018-02-261-2/+2
| | | | | | | | | | | | | From now on we prefer nullptr instead of 0 to clarify cases where we are assigning or testing a pointer rather than a numeric zero. Also, replaced cases where 0 was passed as Qt::KeyboardModifiers with Qt::NoModifier (clang-tidy replaced them with nullptr, which waas wrong, so it was just as well to make the tests more readable rather than to revert those lines).
