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.
The latest builds of Sunrize are available as installer packages on the Sunrize Releases page on GitHub. From there, you can download precompiled binaries, but currently only for Windows.
First you need to install both Node.js and npm on your system. To accomplish this, you can use a Node installer (Windows), or use Homebrew to install node (macos), or use your Linux package manager.
Then you can run Sunrize without installing it using npm's npx command:
$ npx sunrize@latest [files]
Note: The first time, it may take a while for Sunrize to start.
