B) Angled (90°) or Curved LED Walls
• LED screens arranged on multiple angled surfaces to create the illusion of depth and movement.
• Ideal for Anamorphic 3D effects, seen in cities like Tokyo, New York, and Seoul, where objects appear to pop out of the screen.
• Curved LED walls enhance perspective without visible interruptions.
C) Holographic Fans (Hologram Fans)
• Consist of rotating blades with LED lights that generate floating images visible from different angles.
• Can be used individually or in multiple arrays for larger holographic effects.
• Perfect for interactive marketing, trade shows, and events.
D) Combination of LED Walls and Holographic Fans
• By combining both technologies, floating 3D objects can be displayed in front of the LED wall, while the wall itself provides a dynamic background.
• Synchronizing the content enhances the holographic illusion significantly.
E) Use of Mirrors and Reflections on a LED Wall
Using mirrors and reflections on a LED wall is a powerful method to create holographic illusions without the need for wearable devices. The combination of transparent glass, reflective mirrors, and LED walls can create a floating, three-dimensional effect, perfect for shows, events, and futuristic installations. Several techniques are available to achieve this effect:
- Pepper’s Ghost Technique (Reflection on a Transparent Surface)
• One of the oldest and most widely used holographic techniques, based on a transparent glass or reflective screenplaced at a 45° angle between the audience and the LED wall.
• The LED wall displays an image that is hidden from the audience’s direct view, but its reflection on the glass creates the illusion of a floating object in space.
• Used in concerts featuring holographic artists and theatrical performances.
How Does It Work?
1. The LED wall is positioned either horizontally or vertically relative to the audience.
2. A semi-transparent mirror or glass is placed at a 45° angle.
3. The image from the LED wall is reflected, appearing to float in space.
- Double Mirror for 3D Volume Effect
• Uses two reflective mirrors placed at an angle and a LED wall to create a virtual depth effect.
• An object or animation displayed on the LED wall is reflected multiple times, giving the impression of movement in space.
Possible Configurations
1. Parallel mirrors → Creates an infinite repetition effect, ideal for depth illusions.
2. Inclined mirror in front of the LED wall → The object appears to pop out of the display.
- LED Wall with One-Way Mirror for Floating Effect
• A high-brightness LED wall can be combined with a one-way mirror (semi-reflective mirror).
• The audience sees a mix of reflections and real images, creating an overlapping effect between digital and physical elements.
• Used in advertising and retail, to give depth and movement to display objects in shop windows.
2. Software for Creating 3D and Holographic Effects
To fully utilize the hardware above, it is essential to use advanced software capable of handling rendering, perspective adjustments, and content synchronization.
A) Real-Time Rendering Engines
• Unreal Engine: The most powerful tool for creating photo-realistic and interactive 3D content, often used for LED wall effects.
• Unity: Great for optimized 3D content in live events.
• Blender & Cinema 4D: 3D modeling software for detailed scene creation before importing into real-time engines.
B) Mapping and Synchronization Software
• TouchDesigner: Used for real-time artistic installations and live performances.
• MadMapper: Perfect for video mapping on curved or angled LED walls.
• Resolume Arena: Ideal for VJing and live-synchronized animations.
C) Software for Holographic Content
• Holo-Gauze & Looking Glass: Used for 3D interactive content on transparent screens and holographic fans.
• Notch VFX: Creates advanced 3D effects on LED walls in real-time.
3. Special Content Creation for 3D Effects
Content is just as important as technology. Here are some key principles for maximizing the 3D effect:
A) Use of Anamorphic Perspective
• Creating perspective illusions where the image appears to pop out when viewed from a specific angle.
• Perfect for angled or curved LED walls.
B) Realistic Shadows and Lighting
• Using dynamic shadows and consistent lighting enhances the depth perception.
• Ray tracing techniques improve the realism of virtual objects.
C) Parallax Effects and Layering
• Dividing content into multiple depth layers, with elements moving at different speeds.
• This effect works particularly well on transparent LED walls and holographic fans.
D) Interactive and Real-Time Content
• Integration with motion sensors or eye-tracking allows the perspective to change based on the viewer’s position.
• Ideal for museums, showrooms, and exhibitions.
E) Use of Augmented Reality (AR)
• Combining LED walls with AR devices to overlay digital content visible via smartphones or headsets.
• Used for live events, gaming, and artistic installations.
4. Application Examples
These technologies are already widely used in different industries:
✅ Advertising & Digital Signage
• 3D anamorphic billboards in cities like Seoul and New York.
• Interactive storefronts with transparent LED walls and holographic fans.
✅ Events & Live Performances
• Concerts featuring holograms of artists (e.g., Tupac at Coachella).
