Solution Overview

Problem

Existing 3D target point rendering technologies struggle to effectively render 3D target points in virtual accessory models, particularly in terms of display effect and realism.

Innovation Solution

A 3D target point rendering method and apparatus that selects and determines initial 3D target points from mesh vertexes in a target model, acquires depth information to determine non-hidden target points, and renders these points based on display size and rotation angle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional 3D target point rendering is used, then the rendering process is simple, but the display effect and realism are poor

Engineering Contradiction:

Improvedisplay effectVSAvoidrendering process complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The rendering process is segmented into distinct modules: initial 3D target point determination module, non-hidden 3D target point determination module, display size and rotation angle determination module, and 3D target point rendering module. Each module handles a specific aspect of the rendering process, improving overall display effect while maintaining manageable complexity through functional decomposition.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The method performs preliminary actions by determining initial 3D target points from mesh vertexes before actual rendering, and by pre-calculating depth information to identify non-hidden points. This preliminary processing improves the final display effect by ensuring only visible, properly positioned points are rendered with appropriate parameters.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If depth information processing is added to determine non-hidden points, then visibility and authenticity are improved, but computational complexity increases

Engineering Contradiction:

Improvevisibility accuracyVSAvoidprocessing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Depth information serves as an intermediary element that mediates between the 3D target points and the rendering process. The non-hidden 3D target point determination module uses this depth information to filter and select only visible points, improving visibility accuracy while the modular structure keeps processing complexity manageable.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Manufacturing precision

If display size and rotation angle are determined for each point, then realism is enhanced, but processing time increases

Engineering Contradiction:

ImproverealismVSAvoidprocessing time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The method applies local quality by determining specific display size and rotation angle parameters for each non-hidden 3D target point based on its individual characteristics and position. This localized parameter assignment enhances realism by making each point appear authentic and appropriately oriented, while the modular architecture optimizes processing efficiency.

Inventive Principle:

Principle #3Local quality
