Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods for generating 3D sticker effects consume high performance resources and are limited to fixed 3D face models, lacking flexibility and reducing the effectiveness of the sticker generation process.

Innovation Solution

A method and apparatus for generating sticker effects that involve displaying a target face model, selecting and editing stickers on the model, determining display parameter information for the edited stickers, and generating a target sticker effect object based on this information, all without the need for intermediate texture picture files.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If real-time generation of intermediate texture picture for each edit is performed, then sticker effect can be created, but performance consumption is high

Engineering Contradiction:

Improvesticker generation efficiencyVSAvoidperformance consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent pre-generates a three-dimensional face model library containing multiple face models with different expressions and poses before actual sticker creation. This preliminary preparation eliminates the need for real-time intermediate texture generation during editing, significantly reducing performance consumption while maintaining sticker generation efficiency

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of generating new intermediate textures for each edit operation, the patent reuses and combines existing texture components from the pre-generated face models. By copying and assembling pre-existing texture elements, the system avoids redundant computational work and reduces performance consumption

Inventive Principle:

Principle #26Copying

2Productivity

If fixed 3D face model is used, then sticker effect can be generated, but flexibility is reduced

Engineering Contradiction:

Improvesticker generation capabilityVSAvoidface model flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent segments the face model into multiple independent components including different expressions, poses, and texture elements. Each component can be independently selected and combined, providing flexibility while maintaining efficient sticker generation capability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pre-generated three-dimensional face model library serves multiple functions: it provides various expressions, poses, and texture variations that can be universally applied to different sticker creation scenarios. This multi-functional library enhances adaptability without requiring separate processing for each case

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Embodiments of the present disclosure provide a sticker effect generation method and apparatus, an electronic device, and a storage medium. The method includes: displaying an obtained target face model; displaying a selected sticker on the target face model in response to a selection operation for a sticker; determining, in response to an edit operation for the sticker on the target face model, display parameter information about the sticker after the sticker is edited on the target face model, and rendering and displaying the sticker on the target face model based on the display parameter information and a type of the sticker; and generating a target sticker effect object based on the display parameter information about the sticker and the target face model in response to a release operation.
