Solution Overview

Problem

In the process of combining models in a virtual scene, scene designers often face cumbersome workflows due to the lack of pre-defined information about models, leading to repetitive work and the inability to achieve desired effects when combining multiple models.

Innovation Solution

A method, system, and device for combining models in a virtual scene that involves placing a first model into a second model, determining filling and removing spaces, filling the overlapping and filling spaces with the second model, and removing the second model from the removing space, with the filling and removing spaces determined by user instructions or predefined rules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the scene designer manually asks model makers for pre-definitions when combining models, then the model combination can be achieved with correct pre-defined effects, but the workflow becomes cumbersome and time-consuming

Engineering Contradiction:
Improvemodel combination accuracyVSAvoidworkflow time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system enables self-service by automatically determining filling and removing spaces without requiring scene designers to manually query model makers for pre-definitions. The automated space determination mechanism performs the function that previously required human communication and coordination.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary action by pre-calculating and storing filling and removing space information during model creation. This advance preparation eliminates the need for real-time consultations between scene designers and model makers when combining models.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the scene designer manually edits models without pre-defined information, then the workflow can proceed without consulting model makers, but repetitive work increases and desired effects cannot be achieved

Engineering Contradiction:
Improveoperation flexibilityVSAvoidmodel combination efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system provides self-service functionality that automatically handles the complex tasks of determining filling and removing spaces, as well as calculating their volumes. This eliminates repetitive manual editing work while maintaining operational flexibility.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical editing operations with automated computational mechanisms. The system automatically calculates filling and removing spaces using geometric algorithms, substituting the manual measurement and calculation processes that previously required repetitive human effort.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If the system automatically determines filling and removing spaces, then the workflow is simplified and repetitive work is reduced, but the complexity of the automated determination mechanism increases

Engineering Contradiction:
Improvemodel combination efficiencyVSAvoidautomation mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments the complex model combination task into distinct manageable components: determining filling space, determining removing space, calculating their volumes, and executing the combination. This segmentation reduces the perceived complexity by breaking down the automated mechanism into clear, sequential steps.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The automated determination mechanism serves multiple functions through a unified system: it determines both filling and removing spaces, calculates volumes for both spaces, and handles various model combination scenarios. This multi-functionality consolidates what would otherwise require multiple separate tools or manual processes into a single system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention is directed to a method, system, and device for combining models in a virtual scene, and to a coded storage medium in the field of two-dimensional (2D)/three-dimensional (3D) modeling which simplifies the work of the scene designer, reduces repetitive work, and achieves a desirable effect from the models. It includes: placing a first model into a second model; determining a filling space and a removing space of the first model; filling an overlapping space between the first model and the second model with the second model, and filling the filling space of the first model with the second model; and removing the second model with which the removing space of the first model is filled, wherein when the overlapping space between the first model and the second model is filled with the second model, and the filling space of the first model is filled with the second model, the removing space of the first model is filled with the second model.
