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:
- CMake integration for the
- QShader (part of the QtGui module)
- QShaderBaker (part of this module, the library equivalent of the
Articles and Guides
Compiles a GLSL/Vulkan shader into SPIR-V, translates into other shading languages, and gathers reflection metadata
Note: 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.
