YACReader Flow RHI Shaders

This directory contains the GLSL 4.50 shaders for the QRhiWidget-based flow implementation.

Files

• flow.vert - Vertex shader (GLSL 450)
• flow.frag - Fragment shader (GLSL 450)
• flow.vert.qsb - Compiled vertex shader (multi-platform)
• flow.frag.qsb - Compiled fragment shader (multi-platform)
• compile_shaders.bat - Windows compilation script
• compile_shaders.sh - Unix/macOS compilation script
• shaders.qrc - Qt resource file

Compiling Shaders

The shaders must be compiled to .qsb format using Qt's qsb tool before building YACReader.

Prerequisites

Ensure qsb is in your PATH. It's typically located in:

• Windows: C:\Qt\6.x.x\msvc2019_64\bin\qsb.exe
• macOS: /opt/Qt/6.x.x/macos/bin/qsb
• Linux: /opt/Qt/6.x.x/gcc_64/bin/qsb

Compilation

Windows:

cd common/rhi/shaders
compile_shaders.bat

Unix/macOS:

cd common/rhi/shaders
chmod +x compile_shaders.sh
./compile_shaders.sh

The compiled .qsb files contain shader variants for:

• OpenGL ES 2.0, 3.0
• OpenGL 2.1, 3.0+
• HLSL (Direct3D 11/12)
• Metal Shading Language (macOS/iOS)

Note

The .qsb files are included in the repository for convenience. Recompile only if you modify the shader source.
