Overview
A tether line is a visual line that connects the learner’s hand or pointer to an object during interaction. It shows the interaction path and provides visual feedback about what the learner is manipulating. Use Set Tether Line Color to customize the tether line color to match your training theme or highlight specific interactions. Use Reset Tether Line Color to restore the default color.Understanding Tether Lines
Tether lines appear when:- The learner grabs and drags an object
- The learner is moving or rotating a manipulated object
- Pointer-based interaction (ray casting) is active
Set Tether Line Color
When to Use
- Match training theme — Use tether colors that align with your course branding
- Highlight interactions — Change color for specific interaction types (e.g., red for hazardous objects)
- Provide visual distinction — Use different colors for different types of interactions in the same training
- Improve visibility — Adjust color to contrast with complex 3D scene backgrounds
Parameters
Example 1: Standard Blue Tether
Example 2: Red Tether for Hazardous Interaction
Example 3: Green Tether for Safe Handling
Reset Tether Line Color
When to Use
- Restore the default tether color after a special color phase
- Reset to system default between training modules
- Clean up custom colors before transitioning to the next section

Best Practices
1
Use consistent colors
Maintain consistent tether colors throughout your training for easier learner recognition.
2
Ensure contrast
Choose colors that contrast well with your 3D scene background. Test on different devices.
3
Limit color changes
Change tether color only when it adds meaning (hazard indication, theme change, etc.). Don’t change frequently.
4
Document color meanings
If you use multiple tether colors, explain their meanings (e.g., “Red = hazardous, green = safe”).
5
Test visibility
Verify your chosen color is visible against the 3D scene on mobile, tablet, and desktop displays.
6
Reset when appropriate
Return to default color between major training sections for clarity.
