Dynamic Deformation Reconstruction via Programmable Light Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional animated sculptures fail to realistically represent the dynamic deformation of objects, as they rely on schematic physical representations, making it difficult to create a convincing illusion of movement or deformation.
Innovation Solution
A method using a plurality of light sources positioned to correspond with characteristic points of an object during deformation, controlled by a programmer to accurately replicate the object's movement, creating a high-quality visual representation that can be viewed from various angles without the need for complex mechanical devices.

Engineering Contradiction Analysis
1Shape
If animated sculptures with solid elements are used to represent object shape, then the physical representation is recognizable when stationary, but the system cannot realistically represent deformations of the object
Solution Approach 1:
The patent replaces solid mechanical elements with light sources that can be dynamically positioned and controlled. Instead of physically deforming solid sculpture elements, the system uses programmable light sources that emit light at positions corresponding to deformed points on the object surface, enabling realistic deformation representation without mechanical complexity
Solution Approach 2:
The patent creates an optical copy of the object's deformation by positioning light sources at coordinates that match the deformed positions of characteristic points on the object. This optical copying approach allows the system to represent any deformation state without requiring physical analogs of all possible deformation configurations
2Measurement precision
If light sources are used to represent characteristic points during deformation, then the position of light sources corresponds precisely to the position of corresponding points of the object, but the system requires a programmer to control the light sources
Solution Approach 1:
The system achieves self-service by using the object's own characteristic points as reference markers for positioning light sources. The programmer controls light sources based on predetermined coordinates of these characteristic points, allowing the system to automatically maintain precise correspondence between light source positions and object point positions during deformation without requiring external measurement or adjustment
3Adaptability or versatility
If a plurality of light sources are separated by mainly transparent space, then the physical system can be observed from many viewing angles, but the light sources do not represent the shape of the object
Solution Approach 1:
The patent employs periodic action by sequentially activating light sources at different positions corresponding to the object's deformation at successive instants. This temporal sequencing creates the visual perception of continuous deformation and shape representation, allowing the system to convey both shape information and multi-angle observability without requiring all light sources to be simultaneously visible

AI summary
The present invention concerns a three-dimensional physical system for reconstructing the appearance of at least one three-dimensional object in dynamic deformation. The system is composed of a plurality of light sources corresponding to points of said object which are characteristic of said deformations, separated by a mainly transparent space, said plurality of sources not representing the shape of the object, and a programming unit adapted for controlling the light sources so that the relative position of each light source corresponds to the relative position of the corresponding point of said object during the reversible dynamic deformation of same.
