* Delay the deletion of QSGTextures until all windows are synchronizedDominik Holland2017-06-162-0/+3
| | | | | | | | | | | | | | | | With the 'basic' and the 'windows' render loop the scene graph context is shared. Because of this we cannot start deleting textures after the first window is synchronized as it may contain textures needed by the another window, which is not yet synchronized. QWindowPrivate::syncSceneGraph() is not calling endSync() anymore as it doesn't know whether it is the last window or not. Instead the renderloop is now responsible for calling endSync() once this is safe to do.

* Improve dirty region calculation in software rendererJüri Valdmann2017-05-233-36/+55
| | | | | | | | | | | | | | | | | | | | | The software renderers dirty region calculation is done in integral logical coordinates, which leads to quite some trouble when handling scene graph elements with fractional coordinates (used by WebEngine for example). The optimal solution would probably be to either use integral physical coordinates or floating point logical coordinates, however this would seem to require substantial changes to QPainter and QBackingStore and so on. So, this patch instead changes the calculation to use something like interval arithmetic: instead of just rounding each logical coordinate to the nearest integer the renderer now uses (very carefully) both the upper and lower boundaries to make sure that the dirty regions always err on the side of caution. I expect this change to make rendering slower but only in situations where previously there would be rendering errors.

* Software: Flush whole window on Expose eventAndy Nichols2017-02-282-4/+7
| | | | | | | | | | | | | | | The software render loop updates the window content via either an expose event or an update event. An expose event should always flush the entire backingstore, but previously only the newly updated region would be flushed. The first time a window is exposed this is fine because the whole scene would be rendered, but when hidden and shown again, the software renderer might show that nothing has changed, and nothing would be flushed. A new flag has been added that forces a full window flush for an expose event.

| | | | | | | | | | | | | | | | | | | ... when destroying the last window while it is still visible. For the case of windowDestroyed(), the QQuickWindow can still be isVisible true and isExposed true. Given these circumstances, we would not stop the timer (assuming that we needed to keep it running), but this is actually wrong when we are evaluating a timer change depending on the window being destroyed. By calling startOrStopAnimationTimer again, after the window has been removed from m_windows, we will successfully stop the timer -- the only cost being an unnecessary polish event being sent from the first call (which will be ignored).

(it could have been intentional as well - it is confusing in any case and unnecessary). There is no adaptation relying in this anyways - invalidate() is always invoked manually, typically from windowDestroyed. This is very good since it avoids the at first less-than-obvious trouble with emitting invalidated() from the rendercontext dtor. (that can in turn can trigger random amount of code potentially calling back into the rendercontext and rely on virtuals which are not functional anymore due to the vtable not there for the functions in the more-derived class) Change-Id: I44d78c5a819230f7006d33d4341eff45d8f77c88 Reviewed-by: Andy Nichols <andy.nichols@qt.io>

* Software Adaptation: Improve clip node handlingAndy Nichols2016-06-284-9/+25
| | | | | | | | | | | | | | | | This commit solves two issues that were coming up with nested clip nodes. The first was that determining the intersection of two or more nested clip nodes was calculated incorrectly. This was fixed by making sure the calculated clip region was in the correct coordinate space. The second issue was because there was no distinction between an empty unclipped region, and a completely clipped region. So a property was added to specify when a RenderableNode had a clipRegion so that the empty QRegion could be interpreted correctly. This makes sure that we don't end up drawing nodes that were culled. Change-Id: Id7af092f7fc6a4602b44b585b7dee14084136962 Reviewed-by: Laszlo Agocs <laszlo.agocs@qt.io>

QSGSimpleTextureNode is deprecated -> use QSGImageNode via QQuickWindow::createImageNode() instead.

The "style" node from Quick Controls 1 is now QSGNinePatchNode in order to provide a proper cross-backend solution which is already necessary due to the software backend, but now generalize it to apply to the accelerated backends with proper materials as well. QC can now simply call createNinePatchNode() without further ado. Also fixes a bug with the D3D12 texture material not enabling blending when needed. When it comes to the internal class names, QSGRectangleNode and QSGImageNode get the Internal prefix in the adaptation layer in order to differentiate from the public API. This involves quite a lot of renaming, but results in a nice and clean public API. Change-Id: Iddf9f9412377843ea6d652bcf25e68d1d74659ea Reviewed-by: Gunnar Sletta <gunnar@sletta.org>

| | | | | | | | | | | | | | | | | When rendering into QBackingStores, it is important to let the backingstore know what region you intended to paint into before you start rendering. Previously we were calling QBackingStore::beginPaint on the whole window area, but then only rendering and flushing for a subset of that area. This causes issues on platforms that depend on QBackingStore::beginPaint to be all area that will be repainted before the next flush, so that they can for example clear those areas. This change required a bit of extra plumbing in the Software Renderer, but now it is possible to calculate the area that will be repainted before painting it, and pass that region to QBackingStore::beginPaint().

This was a wrong assumption, because the texture data can be different but still use the same pointer. So the node should always respond by updating the texture when setTexture is called and mark the nodes material as dirty for the renderer. This allows canvas items to be updated at runtime with the software renderer. Change-Id: Idf504035a6aa858e865050a58460189a12e77ad4 Reviewed-by: Laszlo Agocs <laszlo.agocs@qt.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The D3D12 node implementation is mostly missing. The rest of the enablers should be in place now however. Importing QtQuick 2.8 provides new properties for ShaderEffect: - shaderType can be used to decide which language should be used - shaderCompilationType tells if compilation is runtime or offline - shaderSourceType tells if the vertex/fragmentShader properties refer to source strings or source files or pre-compiled bytecode files The last two are bitmasks. In practice however we will support only one approach per backend for now (runtime + source string for OpenGL, offline + bytecode for D3D12). In addition to QSGShaderEffectNode, introduce the QSGGuiThreadShaderEffectManager interface. This provides the gui thread bits for the above and performs shader reflection. Backends that use the new ShaderEffect system must provide both. For each ShaderEffect item there will be a manager (on the gui thread) and a node (on the render thread). Reflection is expected to be done via standard helper libs (d3d12shader + D3DReflect from d3dcompiler for the D3D12 backend), or via manually inspecting SPIR-V, or parsing the source (like the GL path does now), or by using some 3rd party library (not recommended). In any case we require that reflection is doable on the gui thread without dependencies to the actual graphics API. The ShaderEffect documentation is greatly extended, covering HLSL and the new properties. The test app uses manually compiled shaders on its HLSL path for now. This is because there is no story yet for build system integration for public use (the internal HLSL -> bytecode in C header rule is only suitable for the d3d12 plugin itself, apps need something different).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
