* Enable D3D12Laszlo Agocs2023-02-141-0/+1
| | | | | | | | | | Windows continues to use D3D11 as the default. To use D3D12 it needs to be requested explicitly, for the time being, either via QSG_RHI_BACKEND=d3d12 or via the QSGRendererInterface enum.

* Fix up exposing the swapchain to Quick3DLaszlo Agocs2020-06-191-0/+2
| | | | | | | | | | Quick3D is broken in combination with QQuickRenderControl. This is because just exposing the swapchain is not enough - there is no swapchain with QQuickRenderControl. Rather, one needs access to the command buffer and render target then. Change-Id: I6c06ad3d83ab0018b9f985073757a3378dbce24b Reviewed-by: Andy Nichols <andy.nichols@qt.io>

* Expose the QRhiSwapchain via QSGRendererInterfaceLaszlo Agocs2020-06-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | ...similarly to how we already do it for the QRhi itself. Just follow the same pattern. This allows Qt Quick 3D to stop peeking directly into QQuickWindowPrivate and accessing member variables in there. Code like the following QQuickWindowPrivate *wd = QQuickWindowPrivate::get(window); QRhiCommandBuffer *cb = wd->swapchain->currentFrameCommandBuffer(); QRhiRenderPassDescriptor *rp = wd->rpDescForSwapchain; can now be written ca. like this, without pulling in quick-private: QRhiSwapChain *swapchain = window->rendererInterface->getResource(window, RhiSwapchain) QRhiCommandBuffer *cb = swapchain->currentFrameCommandBuffer(); QRhiRenderPassDescriptor *rp = swapchain->renderPassDescriptor(); This provides a more stable interface between the scenegraph and Quick 3D. In addition, this is also handy for manual tests, external test applications, etc. in case they do QRhi-based rendering in a QQuickWindow. Now these are also fine with just gui-private, no need to access QQuickWindowPrivate anymore. Change-Id: I921fb1c33c2fc77081272b1f180fdc2c87ed3ab5 Reviewed-by: Andy Nichols <andy.nichols@qt.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* OpenVG Scenegraph AdaptationAndy Nichols2016-12-131-1/+2
| | | | | | | | | | | | | | | | | | This is an OpenVG backend for the Qt Quick 2 scenegraph. Should be feature complete now, but there are still some issues that could be improved in future commits: If Rectangle nodes are rendered with a non-affine transform, they will be rendered incorrectly. This is because paths expect affine transformations. The Glyph cache is a bit cheeky in that it's caching paths, but doing so per font size. It shoudln't need to, but right now I've not though up a good way of getting the transform/scale needed when rendering yet.

* software: Add support for QSGRenderNodeLaszlo Agocs2016-07-191-3/+6
| | | | | | | | | | | | | | | | | Have to change getResource() a bit since it turns out it is not suitable currently for backends that do not have a per-window rendercontext and do not implement the interface on the rendercontext. Pass in the window to make sure it can always figure out which window we want the resources for. (we do not want rendererInterface() to return window-specific instances created on the fly, with ownership issues, so stick with the simple model where backends implement the interface on one of their existing classes) To support clipping, QSGRenderNode::RenderState is extended accordingly. Also updated the docs since some claims in the rendernode docs are not true since Qt 5.3. Change-Id: I34779c83926f5231b888fcab7131e873ae97964f Reviewed-by: Andy Nichols <andy.nichols@qt.io>

* Introduce RendererInfoLaszlo Agocs2016-05-031-3/+1
| | | | | | | | | | | | | | Modeled after OpenGLInfo, RendererInfo.api is an easy to use attached property that reports the current graphics API as long as the item is associated with a window that has the scenegraph initialized. Applications should not worry about this in general since they should target one given API, however tests, examples and some advanced use cases will find this handy. RendererInfo is also a great place to expose other properties in the future. Change-Id: Ie3411b8820fc4b74efd1b1d0143e936886f62d74 Reviewed-by: Andy Nichols <andy.nichols@qt.io>
* Make rendernode suitable for public consumptionLaszlo Agocs2016-04-201-0/+75
For non-OpenGL APIs the primary (and likely the only) way to add custom rendering into the Qt Quick scene is via the render node. Other approaches,like the before/afterRendering signals, QQuickFramebufferObject, remain OpenGL-only. (although QQuickFramebufferObject may get a multi-API replacement based on QSGRenderNode at a later time) Note that this is not a generic 3D content integration enabler. It targets creating 2D and 2.5D Quick items with custom rendering via the graphics API in use. Make QSGRenderNode public, enhance the docs a bit and add a releaseResources(). Add a QSGRendererInterface with a query function in QQuickWindow and QSGEngine. The scenegraph adaptation can then return a custom implementation of the interface. This will be necessary to query API-specific values, f.ex. the ID3D12Device and ID3D12CommandList when running with the d3d12 backend. The interface allows querying the API and void* resources. Resources that we know about in advance are enum-based to prevent the QPlatformNativeInterface-like ugliness of string keys. Support is there in the batch renderer already, fix this up according to the new public API, and implement the corresponding bits for the D3D12 renderer. For D3D12, fix also an issue with QSGNode destruction where graphics resources in use were attempted to be final-released without a proper wait. The semantics of changedStates() in QSGRenderNode is changed so that it can be called at any time, including before render(). This is very useful since we can implement some state restoring in a more efficient manner. Added a new example as well. Documentation for QSGRenderNode is heavily expanded.
