1Measurement precision
If current scene modeling and simulation tools are used, then device complexity is reduced, but measurement precision of plenoptic electromagnetic field is insufficient
Solution Approach 1:
The plenoptic electromagnetic field modeling is segmented into multiple independent solvers including propagator solver for field propagation, interaction solver for object interactions, and material solver for material properties. Each solver handles specific aspects of the plenoptic field, enabling high measurement precision while managing system complexity through modular architecture.
Solution Approach 2:
The modeling system implements a universal plenoptic field representation that can be applied across multiple domains including light transport, imaging, vision, cameras, and sensors. This multi-functional approach allows a single comprehensive system to address various measurement precision requirements without proportionally increasing complexity for each application.
2Reliability
If full plenoptic field resolution is implemented, then physics fidelity is improved, but computational productivity decreases
Solution Approach 1:
The system dynamically adjusts the level of plenoptic field resolution and solver complexity based on scene requirements. Different regions of the scene can utilize different levels of simulation fidelity, allowing high physics fidelity where needed while maintaining computational productivity in less critical areas through adaptive resolution techniques.
Solution Approach 2:
The system implements partial plenoptic field simulation by applying full-resolution modeling only to critical scene elements and interactions, while using reduced-resolution approaches for other regions. This selective application of computational resources maintains adequate physics fidelity for analysis purposes while significantly improving overall simulation productivity.
