Detailed Description

\inmodule QtGui

Since: 6.6

Contains multiple versions of a shader translated to multiple shading languages, together with reflection metadata.

QShader is the entry point to shader code in the graphics API agnostic Qt world. Instead of using GLSL shader sources, as was the custom with Qt 5.x, new graphics systems with backends for multiple graphics APIs, such as, Vulkan, Metal, Direct3D, and OpenGL, take QShader as their input whenever a shader needs to be specified.

Warning: The QRhi family of classes in the Qt Gui module, including QShader and QShaderDescription, offer limited compatibility guarantees. There are no source or binary compatibility guarantees for these classes, meaning the API is only guaranteed to work with the Qt version the application was developed against. Source incompatible changes are however aimed to be kept at a minimum and will only be made in minor releases (6.7, 6.8, and so on). To use these classes in an application, link to {Qt::GuiPrivate} (if using CMake), and include the headers with the rhi prefix, for example {#include <rhi/qshader.h>}.

A QShader instance is empty and thus invalid by default. To get a useful instance, the two typical methods are:

\list

Generate the contents offline, during build time or earlier, using the qsb command line tool. The result is a binary file that is shipped with the application, read via QIODevice::readAll(), and then deserialized via fromSerialized(). For more information, see QShaderBaker.

Generate at run time via QShaderBaker. This is an expensive operation, but allows applications to use user-provided or dynamically generated shader source strings.

\endlist

When used together with the Qt Rendering Hardware Interface and its classes, like QRhiGraphicsPipeline, no further action is needed from the application's side as these classes are prepared to consume a QShader whenever a shader needs to be specified for a given stage of the graphics pipeline.

Alternatively, applications can access

\list

the source or byte code for any of the shading language versions that are included in the QShader,

the name of the entry point for the shader,

the reflection metadata containing a description of the shader's inputs, outputs and resources like uniform blocks. This is essential when an application or framework needs to discover the inputs of a shader at runtime due to not having advance knowledge of the vertex attributes or the layout of the uniform buffers used by the shader.

\endlist

QShader makes no assumption about the shading language that was used as the source for generating the various versions and variants that are included in it.

QShader uses implicit sharing similarly to many core Qt types, and so can be returned or passed by value. Detach happens implicitly when calling a setter.

For reference, a typical, portable QRhi expects that a QShader suitable for all its backends contains at least the following. (this excludes support for core profile OpenGL contexts, add GLSL 150 or newer for that)

\list

SPIR-V 1.0 bytecode suitable for Vulkan 1.0 or newer

GLSL/ES 100 source code suitable for OpenGL ES 2.0 or newer

GLSL 120 source code suitable for OpenGL 2.1 or newer

HLSL Shader Model 5.0 source code or the corresponding DXBC bytecode suitable for Direct3D 11/12

Metal Shading Language 1.2 source code or the corresponding bytecode suitable for Metal 1.2 or newer

\endlist

Member Typedef Documentation

◆ NativeResourceBindingMap

QShader::NativeResourceBindingMap = QMap<int, QPair<int, int> >

Synonym for QMap<int, QPair<int, int>>.

The resource binding model QRhi assumes is based on SPIR-V. This means that uniform buffers, storage buffers, combined image samplers, and storage images share a common binding point space. The binding numbers in QShaderDescription and QRhiShaderResourceBinding are expected to match the binding layout qualifier in the Vulkan-compatible GLSL shader.

Graphics APIs other than Vulkan may use a resource binding model that is not fully compatible with this. The generator of the shader code translated from SPIR-V may choose not to take the SPIR-V binding qualifiers into account, for various reasons. This is the case with the Metal backend of SPIRV-Cross, for example. In addition, even when an automatic, implicit translation is mostly possible (e.g. by using SPIR-V binding points as HLSL resource register indices), assigning resource bindings without being constrained by the SPIR-V binding points can lead to better results.

Therefore, a QShader may expose an additional map that describes what the native binding point for a given SPIR-V binding is. The QRhi backends, for which this is relevant, are expected to use this map automatically, as appropriate. The value is a pair, because combined image samplers may map to two native resources (a texture and a sampler) in some shading languages. In that case the second value refers to the sampler.

Note: The native binding may be -1, in case there is no active binding for the resource in the shader. (for example, there is a uniform block declared, but it is not used in the shader code) The map is always complete, meaning there is an entry for all declared uniform blocks, storage blocks, image objects, and combined samplers, but the value will be -1 for those that are not actually referenced in the shader functions.

Member Enumeration Documentation

◆ SerializedFormatVersion

enum class QShader::SerializedFormatVersion

strong

Describes the desired output format when serializing the QShader.

The default value for the version argument of serialized() is Latest. This is sufficient in the vast majority of cases. Specifying another value is needed only when the intention is to generate serialized data that can be loaded by earlier Qt versions. For example, the qsb tool uses these enum values when the {–qsbversion} command-line argument is given.

Note: Targeting earlier versions will make certain features disfunctional with the generated asset. This is not an issue when using the asset with the specified, older Qt version, given that that Qt version does not have the newer features in newer Qt versions that rely on additional data generated in the QShader and the serialized data stream, but may become a problem if the generated asset is then used with a newer Qt version.

\value Latest The current Qt version \value Qt_6_5 Qt 6.5 \value Qt_6_4 Qt 6.4

◆ Variant

enum QShader::Variant

Describes what kind of shader code an entry contains.

\value StandardShader The normal, unmodified version of the shader code.

\value BatchableVertexShader Vertex shader rewritten to be suitable for Qt Quick scenegraph batching.

\value UInt16IndexedVertexAsComputeShader A vertex shader meant to be used in a Metal pipeline with tessellation in combination with indexed draw calls sourcing index data from a uint16 index buffer. To support the Metal tessellation pipeline, the vertex shader is translated to a compute shader that may be dependent on the index buffer usage in the draw calls (e.g. if the shader is using gl_VertexIndex), hence the need for three dedicated variants.

\value UInt32IndexedVertexAsComputeShader A vertex shader meant to be used in a Metal pipeline with tessellation in combination with indexed draw calls sourcing index data from a uint32 index buffer. To support the Metal tessellation pipeline, the vertex shader is translated to a compute shader that may be dependent on the index buffer usage in the draw calls (e.g. if the shader is using gl_VertexIndex), hence the need for three dedicated variants.

\value NonIndexedVertexAsComputeShader A vertex shader meant to be used in a Metal pipeline with tessellation in combination with non-indexed draw calls. To support the Metal tessellation pipeline, the vertex shader is translated to a compute shader that may be dependent on the index buffer usage in the draw calls (e.g. if the shader is using gl_VertexIndex), hence the need for three dedicated variants.
