* Load pregenerated glyph cache in default DF cacheEskil Abrahamsen Blomfeldt2018-08-171-2/+7
| | | | | | | | | | | | | | | | | | | In order to support quick loading of scenes with lots of text, we support preloading the contents of the distance field cache from a generated file instead of creating all the distance fields on startup. The idea is that when creating a distance field cache for a specific font, the data will be prepopulated. This is stored in a table in the font file and is picked up automatically by Qt when available. [ChangeLog][Text] Support pregenerated loading distance field glyph caches to decrease startup time for applications with large amounts of text.

* software: Add support for QSGRenderNodeLaszlo Agocs2016-07-191-0/+3
| | | | | | | | | | | | | | | | | 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>

* Add cross-backend simple rect, texture, and ninepatch nodesLaszlo Agocs2016-06-221-24/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | QSGSimpleRectNode is deprecated -> use QSGRectangleNode via QQuickWindow::createRectangleNode() instead. QSGSimpleTextureNode is deprecated -> use QSGImageNode via QQuickWindow::createImageNode() instead. The OpenGL version of the simple rectangle node is switched over to the vertex color material instead of flat, to allow for better batching. Use the same concept for nine patch nodes. 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>

* Adaptable shader effect enablersLaszlo Agocs2016-04-291-0/+133
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Enable building Qt Quick module with QT_NO_OPENGL definedAndy Nichols2016-03-221-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | Currently the Qt Quick module depends on either the OpenGL or OpenGLES headers being available at build time. Since we are adding support for adaptations that do not depend on OpenGL, it should be possible to build Qt Quick in environments that do not have OpenGL development headers. This does present many challenges though because in some cases GL types, and classes that require OpenGL are part of the public APIs. However since these classes were never available when QT_NO_OPENGL was defined, it should be possible to redefine the function signatures under this scenario, since it's not possible to break binary compatibility if there never were any binaries to break compatibility with. One of the bigger changes that was necessary to facilitate this change is creating interfaces out of QSGContext and QSGRenderContext. Here the default behavior was usage of OpenGL directly, even though subclasses could override all OpenGL usage. Making them interfaces should bring QSGContext and QSGRenderContext more in line with the other classes present in the adaptation layer.

* Adapt Qt Quick 2 renderer to work with OpenGL Core ProfileSean Harmer2013-11-131-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic approach is to have the batched renderer create and bind a vertex array object if it detects we are using an OpenGL Core profile context. The VAO is bound for the duration of the QQ2 renderer's work cycle and unbound at the end so as to not interfere with any other VAO's a user may wish to use. All shaders have been copied and ported to be compliant with the GLSL 150 core specification which is the minimum for a Core profile context (OpenGL 3.2 Core). We are not using any newer features as yet so this will work anywhere we can get a Core profile context. The QSGShaderSourceBuilder class has been extended to resolve any requests for shaders to the same basefilename with "_core" appended prior to any file extension. This could be extended in the future to allow version, or GPU or platform specific shaders. The QSGShaderSourceBuilder has also been extended to allow it to insert #define definitions in the prologue of a shader. Any such definition is inserted: * After the last #extension directive (if any are found) * Otherwise after the #version directive (if found) * Otherwise at the start of the shader source This is required by the custom particle shaders which make extensive use of such #defines. In addition the mechanism used by the distance field glyph cache to extend the cache with new glyphs has been modified to work (and work more efficiently) when using a Core profile context. Rather than using a shader program and a buffer filling quad to blit the old texture into the new cache texture, we instead use the technique of framebuffer blitting. The existing fallback implementation using glTexSubImage2D() is still available if needed. The DECLARATIVE_EXAMPLE_MAIN macro has been extended to allow easy testing of any of the QtDeclarative examples with a core profile context. Just run the example with QT_QUICK_CORE_PROFILE=1 ./text for e.g. The only ones that may not work out of the box are those that provide GLSL shader source e.g. the customparticles or shader effect examples. These work fine if the shader source is adapted to GLSL 150 core. In the future it may be a good idea to expose some context property to QML that the user can use to determine what shader source variation to provide to Qt Quick. Along these lines it would also be very nice to allow the provision of shader source to ShaderEffect or CustomParticle from a separate source file just as we now do within Qt Quick.

* Avoid ambiguous include guards in SG classesGunnar Sletta2013-02-261-2/+2
| | | | | | | | | These include guards stem from the olden days before the QSG prefix and many of them are conflict prone, which can lead to pretty bisarrer errors for the user. Change-Id: I0e76c68a588404b6e82be9ecc2e7afa3b9a48e78 Reviewed-by: Samuel Rødal <samuel.rodal@digia.com>

* Change antialiasing method for QML2.Kim Motoyoshi Kalland2012-07-131-3/+9
| | | | | | | | | | | | | Since multisampling can require a lot of memory, and might not be supported on some hardware, turn off multisampling and implement antialiasing in the vertex shader instead. The alternative method of antialiasing is implemented for Rectangle, Image, BorderImage and AnimatedImage, and must be explicitly enabled by setting the new antialiasing property.

| | | | | | | | | | | The glyphs are not stored in a fixed 64x64px tile anymore. Glyphs are stored in area equal to <glyph_width> + 10 (margin) x 64px. Allocation is now done with QSGAreaAllocator. When glyph recycling is needed, unused glyphs are freed until the new glyph can fit in the cache. Change-Id: I179a8f17bfe35468bdb63bca5113ea4d0f06c414 Reviewed-by: Yoann Lopes <yoann.lopes@nokia.com>

* Decouple QSGDistanceFieldGlyphNode from it's cache manager.Andrew den Exter2012-03-201-3/+11
| | | | | | | | | | | | | To implement a custom distance field glyph node currently it's necessary to also provide a duplicate implementation of QSGContext::createDistanceFieldGlyphCache() as the default implemention references the cache manager created by createGlyphNode(). By isolating references to the cache manager to just createDistanceFieldGlyph() cache it becomes possible to just overwrite createGlyphNode() and still use the default cache.

* Use a single distance-field cache instance for all sizes of a given font.Yoann Lopes2012-03-191-43/+57
| | | | | | | | | | | Previously we had a different cache instance for each font size, but they all shared the same textures and positions. Only the glyph metrics were specific to each font size. The metrics for each font sizes are now calculated by scaling the metrics of the distance-field size (54px).
