Solution Overview
Problem
Conventional image rendering methods that reduce surface quantities of virtual objects often result in significant loss of model details, leading to poor rendering effects due to direct surface reduction.
Innovation Solution
An image rendering method that involves flattening an original object mesh model, generating a patch model based on a bounding box patch, performing topological reconstruction to reduce surface quantities, and reconstructing a three-dimensional mesh model, thereby retaining model details while reducing rendering resources.

Engineering Contradiction Analysis
1Quantity of substance
If direct surface reduction is performed on the model, then the quantity of surfaces is reduced and rendering resources are reduced, but model details are seriously lost and rendering effect deteriorates
Solution Approach 1:
The model is divided into multiple patches, with different surface reduction strategies applied to different patches. Important patches (those containing critical model details) are retained with higher fidelity, while less important patches undergo greater surface reduction. This segmentation allows selective preservation of model details while achieving overall surface reduction.
Solution Approach 2:
Different quality levels are assigned to different regions of the model based on their importance. The method identifies and preserves critical surfaces that contain essential model details, while allowing non-critical surfaces to be reduced. This local differentiation ensures that model details are maintained in important areas while reducing overall complexity.
2Manufacturing precision
If a large quantity of surfaces is used in the model, then model details are preserved and rendering effect is improved, but rendering resources are increased
Solution Approach 1:
Instead of uniformly reducing all surfaces, the method applies surface reduction selectively to only those patches that can tolerate reduction without losing critical details. Important patches maintain their original surface count, while less important patches undergo reduction. This partial action approach preserves necessary model details while achieving rendering resource optimization.
Solution Approach 2:
The method changes the surface count parameter differently for different patches based on their importance. Critical patches maintain high surface counts to preserve details, while non-critical patches use lower surface counts to reduce rendering resources. This parameter differentiation resolves the contradiction between detail preservation and resource efficiency.
