# 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:**
|
|
```cmd
|
|
cd common/rhi/shaders
|
|
compile_shaders.bat
|
|
```
|
|
|
|
**Unix/macOS:**
|
|
```bash
|
|
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.
