* rhi: Make QSGRenderNode usable in Quick3Dv5.15.0-beta2Laszlo Agocs2020-03-111-0/+2
| | | | | | | | | | | | Cannot just rely on a render() function, need a point where the "prepare" step can be performed, outside the main renderpass. Also enables proper m_useDepthBuffer handling for the RHI code path.

* Implement QSGRenderNode for the rhi pathLaszlo Agocs2019-08-221-29/+74
| | | | | | | | | | | | | | The documentation is also refined and extended. Revise the rendernode example as well: make it possible to test and demonstrate both scissor and stencil based clipping. An implementation of the triangle for another graphics API should follow in a separate patch at a later point. For now only OpenGL is supported in combination with the RHI.

* use nullptr consistently (clang-tidy)Shawn Rutledge2018-02-261-4/+4
| | | | | | | | | | | | | 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).

* Add QQuickPathItem and its backend infraLaszlo Agocs2016-12-191-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic backend uses the triangulator from QtGui, but is in fact OpenGL-only for now due to materials. The NVPR backend uses GL_NV_path_rendering on NVIDIA hardware with OpenGL 4.3+ or OpenGL ES 3.1+. The software backend simply uses QPainter. With the generic backend each PathItem is backed by a non-visual root node and 0, 1 or 2 child geometry nodes, depending on the presence of visible stroking and filling. The potentially expensive triangulation happens on updatePolish(), on the gui thread. This is proven to provide much smoother results when compared to doing the geometry generation on the render thread in updatePaintNode(), in particular on power-limited embedded devices. The NVPR backend uses a QSGRenderNode in DepthAware mode so that the batch renderer can continue to rely on the depth buffer and use opaque batches. Due to not relying on slow CPU-side triangulation, this backend uses 5-10 times less CPU, even when properties of the path or its elements are animated. The path itself is specified with the PathView's Path, PathLine, PathArc, PathQuad, etc. types. This allows for consistency with PathView and the 2D Canvas and avoids a naming mess in the API. However, there won't be a 100% symmetry: backends like NVPR will not rely on QPainterPath but process the path elements on their own (as QPainterPath is essentially useless with these APIs), which can lead to differences in the supported path elements. The supported common set is currently Move, Line, Quad, Cubic, Arc. The patch introduces PathMove, which is essentially PathLine but maps to moveTo instead of lineTo. More types may get added later (e.g. NVPR can do a wide variety of optimized rounded rects, but this requires directly specifying a GL_ROUNDED_RECTx_NV command, thus neededing a dedicated Path type on our side too) For filling with gradients only linear gradients are supported at the moment. In addition to the declarative API, a more lightweight, QObject-less JS-callable API should be considered as well for the future.

* Add optional flags and rect to QSGRenderNodeLaszlo Agocs2016-08-021-0/+67
| | | | | | | | | | | | Having rendernodes triggering fullscreen updates with the software backend is not ideal. Therefore, introduce the option of reporting that the rendernode is well-behaving, meaning it only writes inside the reported bounding rectangle. Similarly, the OpenGL batch renderer can keep using the depth buffer when the rendernode is known to behave like the renderer expects.

* software: Add support for QSGRenderNodeLaszlo Agocs2016-07-191-11/+23
| | | | | | | | | | | | | | | | | 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>

* Make rendernode suitable for public consumptionLaszlo Agocs2016-04-201-28/+207
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
