Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time simulation of elastic body physical motion is implemented on mobile terminals, then animation effect quality is improved, but computing load increases excessively
Solution Approach 1:
The patent divides the mesh into multiple sub-meshes, where each sub-mesh can be simulated and rendered independently. This segmentation reduces the computing load for each individual simulation while maintaining overall animation quality through composition of multiple sub-mesh animations.
Solution Approach 2:
The patent applies level-of-detail (LOD) technology to perform partial simulation - only simulating mesh portions that are visible or important, rather than simulating the entire mesh at full detail. This reduces computing load while maintaining acceptable animation quality for the user's view.
2Manufacturing precision
If high-resolution rendering mesh is used to ensure exquisite picture quality, then animation effect quality is improved, but subdivision processing load increases
Solution Approach 1:
The patent pre-configures mapping relationships between simulation mesh and rendering mesh in advance. This preliminary preparation allows the system to directly apply pre-computed mappings during runtime without performing complex subdivision processing in real-time, thus reducing processing load while maintaining high picture quality.
Solution Approach 2:
The patent creates a mapping relationship that copies geometric information from the simulation mesh to the rendering mesh. Instead of performing complex subdivision operations, the system uses the mapping to transfer vertex positions and other attributes, achieving high-resolution rendering with reduced computational overhead.
3Manufacturing precision
If mesh subdivision is performed to improve animation quality, then picture quality is improved, but processing time increases
Solution Approach 1:
The patent performs mesh subdivision and mapping relationship establishment in advance during the asset creation phase. By completing these computationally intensive operations beforehand, the system avoids performing subdivision during runtime, thus maintaining high animation quality while minimizing processing time during actual playback.
Solution Approach 2:
The patent extracts the subdivision processing from the real-time simulation pipeline and moves it to an offline preparation stage. This separation allows the system to maintain high animation quality through pre-computed detailed meshes while keeping real-time processing time minimal by only applying pre-established mappings during playback.

AI summary
This application provides a display processing method and an electronic device. A mapping relationship between a simulation mesh and a rendering mesh is preconfigured, so that the corresponding rendering mesh can be directly obtained based on the mapping relationship after the simulation mesh is determined. In this way, physical computing load is reduced as much as possible while an exquisite picture quality effect is ensured, thereby implementing an exquisite animation effect. The method includes: An electronic device determines, in response to a first operation of a user, a theme used by the electronic device, where the theme includes an elastic body displayed on an always on display screen. Then, the electronic device obtains a simulation mesh corresponding to the elastic body; and maps the simulation mesh to a rendering mesh based on a mapping relationship. The electronic device displays, based on the rendering mesh, the always on display screen including the elastic body.
