ShaderToy

A Gtk4 demo application using the Gtk4 shard.

Compile time dependencies

You need the GTK libraries and their GObjectIntrospection files.

Archlinux: pacman -S gtk4 gobject-introspection
Ubuntu: apt-get install libgtk-4-1 gobject-introspection gir1.2-gtk-4.0
macOS: brew install gobject-introspection gtk4

Runtime dependencies

Just the GTK libraries are needed at runtime, i.e. not the gobject-introspection library and files.

Execution

Use the script build.sh to compile the project. To run the ShaderToy application, run ./shadertoy.out.

Note: OpenGL raymarching code not included.
