TransformControls Multiple Modes

Based on the documentation, TransformControls in Three.js is designed to operate in a single mode at a time. The standard modes are:

• Translate
• Rotate
• Scale

Unlike Fabric.js which provides a combined transformation interface with handles for all operations simultaneously, TransformControls typically requires you to switch between these modes.

Possible Workarounds

While there's no direct way to enable all modes simultaneously with the standard TransformControls, you might consider these approaches:

1. Use multiple TransformControls instances - Create separate instances for translation, rotation, and scaling, and attach them to the same object. However, this might lead to visual clutter and interaction conflicts.

2. Create a custom control - Develop your own custom control that combines the functionality of all three modes, inspired by Fabric.js's approach.

3. Modify TransformControls source - Fork the TransformControls code and modify it to support multiple modes simultaneously.

4. Use keyboard modifiers - Implement a system where holding certain keys temporarily switches between modes while interacting.

5. UI mode switching - Add UI buttons that allow users to quickly toggle between modes.

If you need the specific Fabric.js-like experience with all transformation handles visible at once, you'll likely need to create a custom solution or modify the existing TransformControls implementation.
