ShaderMania features live coding of Metal fragment shaders with realtime preview and playback. Shaders are displayed as nodes which can be connected as needed.

ShaderMania features a database of public shaders including tutorial shaders with links to explanation videos.

ShaderMania is 100% free, optionally you can make a small donation to the author (in the AppStore or via PayPal).

A physical keyboard is recommended for coding shaders.

Features

• Flexible node system supporting Shaders and Images. Named input slots for shaders can be created inside the shader source code.
• Connect shader nodes to be able to chain shaders.
• Optional abstracted parameter definition which supports display of variables as sliders to live change shader values in the user interface.
• Tutorial shaders can display a button with a link to their video urls.
• Realtime syntax check and compilation of your shaders with realtime preview.
• Render to custom resolutions and export your shader output to PNG.
• Display of syntax errors and warnings.

Database

• Upload your shaders to the public shader database
• Browse shaders in the Database and learn / experiment.
• Add the nodes of shaders in the database to your project.

As mentioned above, a small donation to the author (in the AppStore or via PayPal) helps. But simply rating or reviewing ShaderMania in the AppStore is also a great help as it improves visibility.

• Thanks to The Art of Code for allowing me to use his tutorial shaders.
• Thanks to Kali for allowing me to use his Fractal Land shader for the app.
