Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In film production, especially in virtual environments, achieving accurate and dynamic lighting is time-consuming and costly, as existing methods require pre-rendering lighting sequences, making real-time adjustments difficult and expensive.
Innovation Solution
A computer-implemented method and system for dynamically controlling a light box system, which loads a virtual environment, determines lighting parameters, and generates instructions to control light projection elements based on the virtual environment's elements and location, allowing for real-time lighting adjustments within the light box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pre-rendering lighting sequences is used for virtual environments, then lighting accuracy is improved, but production time and cost increase
Solution Approach 1:
The system transitions from static pre-rendered lighting to dynamic real-time lighting control. The light box system continuously adjusts lighting parameters based on the virtual environment being displayed, allowing lighting to change dynamically as the virtual scene changes without requiring pre-rendering or production stops.
Solution Approach 2:
The system creates a real-time optical copy of the virtual environment's lighting by analyzing the rendered virtual scene and reproducing its lighting characteristics through the light box. This copying approach achieves accurate lighting representation without requiring separate pre-rendering passes.
2Stability of the object's composition
If pre-rendering lighting sequences is used, then lighting consistency is improved, but adaptability to scene changes deteriorates
Solution Approach 1:
The system implements a feedback loop where the rendered virtual environment is continuously analyzed and fed back to the light box control system. This feedback mechanism allows the lighting to automatically adjust and adapt to any changes in the virtual scene while maintaining consistency with the intended lighting design.
Solution Approach 2:
The lighting system becomes dynamic and responsive to scene changes. When the virtual environment is modified during production, the light box automatically updates its lighting output in real-time, providing both consistency with the new scene state and adaptability to changes without requiring pre-rendering.
3Illumination intensity
If large LED screens are used to produce light for virtual environments, then lighting realism is improved, but system complexity and cost increase
Solution Approach 1:
The system divides the lighting control into discrete controllable elements within the light box. By segmenting the lighting into individual controllable components and using computational algorithms to manage each segment based on the virtual environment, the system achieves realistic lighting without requiring an entire wall-sized LED screen.
Solution Approach 2:
The system introduces a computational intermediary (the control system that analyzes the virtual environment and translates it into lighting commands) between the virtual environment and the physical light box. This intermediary enables realistic lighting reproduction through software algorithms rather than requiring massive hardware displays.
4Adaptability or versatility
If post-processing techniques are used to add lighting effects, then lighting flexibility is improved, but production efficiency deteriorates
Solution Approach 1:
The system performs preliminary lighting setup by pre-configuring the light box with the ability to reproduce various lighting conditions. However, unlike post-processing, the lighting is applied in real-time during filming rather than added later, maintaining both flexibility and production efficiency.

AI summary
This disclosure relates to systems and methods for controlling a light box system. The light box system can be used to create lighting for a virtual environment. The light box system, also referred to as a light box, can be formed from a plurality of walls that form a room-like structure. Each wall of the light box can include a plurality of light projection elements. The light projection elements can be light emitting diodes (LED) that can project light within the interior of the light box. The light projection elements can output light towards the interior of the light box in order to generate calculated light output for a virtual environment. The lighting characteristics of the virtual environment can be modified to change the calculated lighting output for a virtual environment.
