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 command-line tool
  • CMake integration for the qsb tool
  • QShader (part of the QtGui module)
  • QShaderBaker (part of this module, the library equivalent of the qsb tool)

Note: As of Qt 6.4, the C++ APIs are considered private. They are not recommended for direct usage from applications. Rather, use the qsb command-line tool either directly, or indirectly from CMake projects.
