* Fix up the scenegraph/textureinthread exampleLaszlo Agocs2020-05-181-1/+1
| | | | | | | | | | | | | Force OpenGL, remove the ShaderEffect (it serves no purpose in this example) and remove deprecated API usage. Finally, rename the example to opengltextureinthread. Note that the example's performance is sub-par, but the same is true with direct OpenGL. Change-Id: I7eaa2349ffdb3d27bd9e8815d674e918bc709c03 Reviewed-by: Eirik Aavitsland <eirik.aavitsland@qt.io>

| | | | | | | | | | And port the graph example to QSGMaterial and the RHI. We will not anymore add a direct OpenGL path (that would mean using QSGMaterialShader) for the example because the upcoming purge renders that useless anyway.

* Remove QSGEngine and move QSGAbstractRenderer back to privateLaszlo Agocs2020-04-071-1/+0
| | | | | | | | | | | | | | | | | | | QSGEngine goes away. Same for the associated example, which is the only place this is used anywhere in Qt. As a consequence, the renderer base class can be moved back to private: there is no use for it to be public anymore, since that made sense only in combination with QSGEngine. With the RHI-based rendering path driving a renderer directly is more complicated than before so it is not reasonable to allow the QSGEngine-style access anymore. Instead, one has QQuickRenderControl, which allows redirecting and manually driving the rendering of a QQuickWindow, thus providing an alternative to the legacy QSGEngine approach.

* Rename textureinsgnode example to a more fitting nameLaszlo Agocs2019-09-121-1/+1
| | | | | | | | | | | | | | It shows QQuickFramebufferObject. "Texture in QSGNode" is ambiguous as it suggests another type of use case (where an existing texture is imported and used with the QQ scene - without rendering to it). This would conflict with upcoming future examples, so rename to fboitem, which is what this example is about. The link from examples.qdoc is already using the fitting title so that will just work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
