* Basic working compressed texture atlasMichael Brasser2018-01-311-27/+61
| | | | | | | | | | | | | This adds experimental automatic atlasing of ETC-compressed textures (to be expanded to additional formats), similar to existing atlas support of QImages. It is off by default, and can be enabled with QSG_ENABLE_COMPRESSED_ATLAS=1.

| | * Allow more control over memory/speed tradeoff in the atlas.Michael Brasser2016-04-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QSG_ATLAS_TRANSIENT_IMAGE_THRESHOLD can be used to define a threshold for retaining the QImage associated with an atlas texture. This gives more control to the developer on platforms where removing a texture from the atlas (e.g. for use in a ShaderEffect) can be prohibitively expensive.

* | | Enable building Qt Quick module with QT_NO_OPENGL definedAndy Nichols2016-03-221-5/+5
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add QQuickWindow::TextureIsOpaque as option to createTextureFromImage.Gunnar Sletta2015-06-151-1/+2
| | | | | | | | | | | | | | | | Opaque textures can be a lot faster, so give this option without forcing the user to reimplement her/his own QSGTexture class. The old behavior was that createTextureFromImage() disregarded TextureHasAlphaChannel and looked solely at the image's format. To keep this behavior intact, we introduce a second opt-in flag to switch textures from auto-detect to false, namely TextureIsOpaque.

Also, ditch the extra QRect used to store the nonpadded atlas rect as this is easily reachable from the padded one.

* Use one render loop per QQuickWindowGunnar Sletta2013-10-301-4/+6
| | | | | | | | | | | | | | | | | | | See the task for the full reasoning behind this patch. The threaded renderloop has been refactored to have one window per thread. This is mostly a simplification of the current code path where for loops over multiple windows are turned into if (window). The QSGContext has been split into two classes, QSGRenderContext for which there is one per OpenGLContext. The rest of the patch is name changes and a couple of cleanups in the hopes of simplifying this change.

* New scenegraph renderer and atlas textures.Gunnar Sletta2013-09-021-0/+156
The renderer tries to batch primitives together where possible, isolate non-changing subparts of the scene from changing subparts and retain vertexdata on the GPU as much as possible. Atlas textures are crucial in enabling batching. The renderer and atlas texture are described in detail in the doc page "Qt Quick Scene Graph Renderer".
