FroggyFrag

An OpenGL fragment shader preview tool, for assisting in shader development.

Build Instructions

1. Install GCC.
2. Download the repository git clone https://github.com/mroemore/FroggyFrag/.
3. Enter the project directory cd FroggyFrag.
4. Run make release.
5. Copy the contents of bin/ to a location of your choice.
6. Run froggy-frag.

Usage Instructions

Keybindings

• [R] Reload currently loaded shader.
• [= or ➡️] Load next shader.
• [- or ⬅️] Load Previous Shader.
• [F5] Rescan shader directory.
• [Q] Show/hide message console.
• [A] Toggle automatic reloading of shaders.

Config Settings

Edit the config.json file and restart the application to change these settings.

• contentW, contentH : changes the render resolution of the background image, irrespective of the image resolution.
• screenW, screenH : change the default shader and window resolution. resizing the application window after the program starts effectively overrides this.
• shaderFileExtension : default is .glsl but you can change this if you've used a different naming convention for your fragment shaders.
• systemFontPath : path to the default system font.
• shaderFolder : path to the folder which contains your shaders.
• backgroundImagePath : path to the default background image.
• screenshotsFolder : default save location for screenshots. [NOT YET IMPLEMENTED]
• imagesFolder : default location for image resources which shaders can be rendered over.
• autoReload : set this to false if you want to manually reload shaders.
• reloadCheckInterval : a value in seconds after which the application will check for changes in the currently selected shader file.
• maintainContentAspectRatio : set this to true if you would like the aspect ratio of your shader to remain the same after resizing the window. [NOT YET IMPLEMENTED]
• copyOnDrag : set this to true if you would like the application to copy images or shaders to the 'resources' directory when they are dragged onto the application window. [NOT YET IMPLEMENTED]

Upcoming Features

• Drag and drop loading of images and shaders.
• Keybindings for cycling through background images.
• Aspect ratio settings.
• Config files for customization of shader variables.
• Screenshots.
