* Clean up QT_CONFIG(opengl)Paul Olav Tvete2020-06-172-62/+11
| | | | | | | | | | Accelerated graphics is now possible without OpenGL support. With this change, a Qt build with -no-opengl can still run Qt Quick with a Vulkan, Metal, or Direct3D backend.

* Anisotropic antialiasing for distance field textEskil Abrahamsen Blomfeldt2020-06-152-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For perspective transforms, we need to find the sample range in the glyph cache per pixel. We can do this by getting the gradient of the distance field at the specific pixel. This will ensure proper antialiasing with any projection, but has the limitation that when glyph contours become thinner than a pixel, they may disappear or become too emphasized, because the hardware-gradient - based on neighbouring fragments - is not reliable at that scale. So we should only default to this when we detect that the text is child of a 3D scene. To make this smooth, we need to know the mode of the renderer when creating the shader. So QSGMaterial::createShader() now takes a render mode that we can use to customize behavior based on whether it is rendering into a 2D or 3D scene. [ChangeLog][QtQuick] The QSGMaterial::createShader() virtual function has been extended to take a render mode argument, which can be used for any customizations needed in the case where the shader will be used in combination with 3D perspective transformations.

* Remove OpenGL dependency from QSGTextureLaszlo Agocs2020-06-082-98/+0
| | | | | | | | | | | | | | | | | The QSGTexture API is now clean, the OpenGL-specific functions are removed. Docs are to be updated in a separate patch. QSGPlainTexture, and a number of texture related places have to follow suit. The OpenGL atlas texture implementation is now removed.

* Make QSGMaterialRhiShader become QSGMaterialShaderLaszlo Agocs2020-06-0227-2570/+17
| | | | | | | | | | | | | | | | After a symbiotic relationship in Qt 5.14 and 5.15, it is time for QSGMaterialRhiShader to devour its older sibling and take its place. This makes the direct OpenGL rendering path disfunctional. All QSGMaterial Qt 6 TODOs are solved, the API is clean and straightforward again: a QSGMaterial creates a QSGMaterialShader, no special flags and options needed. (it's just that QSGMaterialShader now has a slightly different API) Task-number: QTBUG-79268 Task-number: QTBUG-82997 Change-Id: I545ca8d796c5535e81957c706e7832133be15b7d Reviewed-by: Eirik Aavitsland <eirik.aavitsland@qt.io>

* Store DXBC instead of HLSL source in the qsb filesLaszlo Agocs2020-05-267-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the -c argument when invoking qsb. The scripts are batch files already so they imply being run on Windows. With a standard VS prompt one gets fxc in the PATH too so we can let qsb invoke it. The result is that the built-in materials' qsb files do not contain HLSL source code anymore, rather they have the intermediate format with bytecode (conceptually this is like SPIR-V). So at run time there are no calls to d3dCompile() anymore when these shaders are involved. What does this mean in practice? With a few select examples: shapes, opening the Gallery view - before: 80 ms spent on HLSL source compilation - after: 0 ms. imageparticle, opening the first 3 views - before: 166 ms spent on HLSL source compilation - after: 0 ms shadereffects - before: 77 ms spent on HLSL source compilation - after: 29 ms (because this has custom shaders that still ship HLSL source) Long term this can hopefully be folded into qsb's to-be-implemented build system integration, so that it can automatically invoke the appropriate shader compiler on Windows and macOS. But for now we just do it manually and check in the regenerated .qsb files. Fixes: QTBUG-84268 Change-Id: Ibe2f80f99b3e52d5eb5eb808ea103cc766d22c04 Reviewed-by: Andy Nichols <andy.nichols@qt.io>
* Move updateRhiTexture and co. to QSGTextureLaszlo Agocs2020-04-281-3/+3
| | | | | | | | | | | | | | | | | | | Use a more descriptive name, commitTextureOperations() in order to avoid confusion with QSGDynamicTexture::updateTexture() which has nothing to do with this. With this the QSGTexture interface has all 5.14 pending changes done (changes that were plumbed via ugly hacks due to having had to deal with binary compatibility). The awful enforcing of subclassing QSGTexturePrivate for each and every QSGTexture subclass is now eliminated. Purging the direct OpenGL code path will involve removing QSGTexture functions like textureId(), bind(), updateBindOptions(). With this patch we now we have all the equivalents (or, in some cases, spiritual successors) in place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add unused volatile pointers to the type registration functions in each import plugin. We need to do this in order to prevent the linker from optimizing the registration away. There are two ways for this to happen: When linking statically, the linker will examine the referenced symbols on a per-object base and leave out all unreferenced objects. When linking dynamically, the linker may do the same on a per-library base and drop any unreferenced libraries from the dependencies. Forcing a reference to the type registration function prevents both. The volatile technique allows us to remove the previous qCDebug() hack. Having an unused volatile auto variable should only result in a single memory read as runtime overhead. The qCDebug() technique would generate a read and a block of mostly dead code (as no one would ever use that logging category).

This greatly reduces the potential for mistakes and resulting incompatibilities between versions of imports. We assume that for each type we need to register all revisions of its super types and its attached type, and that the revisions match. That is, if you import version X of type A, you will also get version X of its attached type and of any super types. As we previously didn't take these dependencies into account when manually registering the types, a number of extra revisions are now registered for some types. Potentially, we can now generate the qmltypes files at compile time, using moc.

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>
