Sunrize — A Multi-Platform X3D Editor
Sunrize is based on X_ITE and is a basic editor for X3D files. The scene can be edited in an Outline Editor and there is a Script Editor where Script nodes and ComposedShader nodes can be edited.
You can run Sunrize without installing it using npx:
$ npx sunrize [files]
Note: The first time, it may take a while for Sunrize to start.
