| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Include the scenegraph autotest in the testrun.Gunnar Sletta2015-03-273-4/+5
| | | | | | | | | | | The mipmap test has been updated to work on chips without npot, but because it is failing in ci on some linux machines, we keep it enabled for OSX and windows only. The test also includes a dump of GPU capabilities to aid in debugging. Change-Id: Ief3092b8e0502bea06aaf4a20c03b7edfa0b2403 Reviewed-by: Simon Hausmann <simon.hausmann@theqtcompany.com>

* Fix opacity issue in the renderer.Gunnar Sletta2014-06-051-0/+90
| | | | | | | | | | | | | | | | | | | | | | Given the following tree: OpacityNode | TransformNode (which is a batch root) | GeometryNode If both opacity and transform nodes were changed this frame, we would hit the optimized "scrolling" path while traversing the tree and abort updating that subtree. As a result the opacity change was not propegated to the geometry node and it would be rendered incorrectly. Fix this by skipping the optimized path when there are opacity changes in an ancestor.

* Invalidate all batches potentially affected by a change.Gunnar Sletta2014-03-191-0/+103
| | | | | | | | | | | | When two separate changes have occurred, we need to not only invalidate the batches directly overlapping those, but also any batch which has render orders between the two. So, keep track of the range of invalidated render orders and invalidate everything in between.

| | | | | | | | | | | | We pretransform vertices relative to their batch root and upload these using single-precision floats. If the offsets are huge then the floating point numbers start to get unstable and we get rendering artifacts as a result. This typically happens for lists/tables with huge models.

* Use one render loop per QQuickWindowGunnar Sletta2013-10-306-0/+223
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.
