Aerial Light Show Occlusion Control for Clear 3D Scenes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerial light show systems fail to create a realistic and unambiguous 3D illusion due to inconsistent visibility of light beams from different viewpoints, as lights are uniformly emitted without considering occlusion by virtual 3D objects, leading to ambiguity and diminished visual effect.
Innovation Solution
Aerial vehicles equipped with light sources that project multiple beams in specified directions, with brightness and color control systems to modify or maintain light emission based on occlusion by the virtual 3D scene, ensuring proper occlusion and transparency effects from various viewpoints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lights are uniformly emitted from all aerial vehicle positions without considering occlusion, then the system is simple to operate and control, but the 3D illusion becomes ambiguous and the visual effect is diminished from certain viewpoints
Solution Approach 1:
The system pre-calculates occlusion relationships between light positions and virtual 3D objects before the light show execution. Occlusion masks are generated in advance based on the virtual scene geometry, allowing the control system to selectively dim or turn off lights that would be occluded, thereby maintaining 3D illusion clarity without requiring complex real-time calculations during performance
Solution Approach 2:
Instead of uniformly controlling all lights, the system applies different brightness characteristics to different light beams based on their specific spatial relationships with virtual objects. Each light beam's intensity is locally adjusted according to whether it should be occluded from specific viewpoints, creating realistic occlusion effects without requiring complex global control mechanisms
2Reliability
If all light beams are emitted with full brightness, then the light show is visually striking and energetic, but occluded lights create ambiguity and break the 3D illusion
Solution Approach 1:
The system dynamically adjusts light beam brightness based on the viewer's perspective and the virtual scene geometry. Occluded light beams are dimmed or turned off while visible beams maintain full brightness, creating realistic occlusion effects. This dynamic control is achieved through pre-calculated occlusion masks that guide intensity adjustments without requiring complex real-time sensing
Solution Approach 2:
The system changes the intensity parameter of light beams selectively based on occlusion relationships. By modifying only the brightness parameter of occluded lights while leaving visible lights unchanged, the system achieves accurate occlusion effects with minimal impact on overall visual impact and energy consumption
3Reliability
If the system pre-calculates occlusion masks for all light positions, then occlusion effects are accurate and 3D rendering is clear, but the computational complexity and processing time increase
Solution Approach 1:
The system performs occlusion calculations and generates occlusion masks in advance, before the aerial light show execution. This pre-computation approach transfers computational complexity to the preparation phase, allowing accurate occlusion rendering during performance without requiring complex real-time processing or sophisticated hardware systems
Solution Approach 2:
The system creates a virtual copy of the 3D scene and uses ray-casting or similar algorithms in this virtual environment to determine occlusion relationships. This virtual modeling approach simplifies the computational problem compared to real-time physical measurement, enabling accurate occlusion masks to be generated with relatively simple processing systems

AI summary
An aerial light show system includes aerial vehicles configured to move along paths consisting of positions while emitting light beams to present an aerial light show of a virtual 3D scene. Each aerial vehicle includes a light source configured to project multiple light beams in multiple specified directions, respectively, wherein the brightness and/or color of each of the multiple light beams is independently controllable. The aerial light show system includes a control system configured to control the movement of the aerial vehicles, to modify the brightness and/or color of (e.g., dim or turn off) a light beam of each aerial vehicle at each position projected in a specified direction that is occluded by the virtual 3D scene, and to not modify the brightness and/or color of a light beam of each aerial vehicle at each position projected in a specified direction that is not occluded by the virtual 3D scene.
