Qt Shader Tools

The Qt Shader Tools module builds on the SPIR-V Open Source Ecosystem as described at the Khronos SPIR-V web site .

The main components of the Qt shader conditioning system are:

the qsb 命令行工具
CMake integration for the qsb tool
QShader (part of the QtGui 模块)
QShaderBaker (part of this module, the library equivalent of the qsb 工具)

C++ API

Compiles a GLSL/Vulkan shader into SPIR-V, translates into other shading languages, and gathers reflection metadata

注意： Applications and libraries should avoid using the C++ API directly, unless they have a good reason to do so. Rather, prefer relying on offline pre-processing by invoking the qsb command-line tool at build time via CMake, or manually if invoking via CMake is not feasible. The qsb tool uses QShaderBaker and writes the serialized version of the generated QShader into a file. The usage of the C++ API should be restricted to cases where run time processing and translation cannot be avoided, and the performance implications are understood. An example of this are applications that work with user-provided or dynamically generated shader source strings.
