ShaderMania vs PharoSmalltalk

Create, edit, render, share, and learn Metal shaders with ShaderMania for iPad. ShaderMania is a visual Metal shader editor for iPadOS. Write fragment shaders with realtime preview and playback, organize shaders and images as nodes, connect shader inputs, expose parameters as sliders, and export rendered images. ShaderMania also includes a public shader library with examples and tutorial shaders, including links to explanation videos where available. ShaderMania is free to use. Optional tips are available if you want to support development. A physical keyboard is recommended for coding shaders on iPad. Features • Live Metal fragment shader editing with realtime preview and playback. • Visual node graph for shader and image nodes. • Connect shader nodes to build reusable shader chains. • Named shader input slots declared directly in shader source code. • Parameter annotations for sliders and live UI controls. • Realtime syntax checking, compiler errors, and warnings. • Render to custom resolutions and export PNG images. • Undo and redo for common node graph edits. Shader Library • Browse public shader examples and tutorial shaders. • Add shaders from the library to your own projects. • Upload useful, inspectable shader work to the public library.
