Inheritance-Based Avatar Generator for Rapid Character Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer animation processes require significant time and resources to generate and render individual characters, especially for complex animations, as each character is modeled and rendered individually, leading to high production costs.
Innovation Solution
A method involving a three-generation inheritance-based avatar generator that allows users to select grandparents and apply weighting factors to generate offspring avatars, reducing the need for manual modeling and rendering by using inheritable characteristics to create a wide range of characters efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual characters are modeled and rendered manually, then character quality and detail are improved, but production time and cost increase significantly
Solution Approach 1:
The system uses template-based avatar generation where pre-defined character templates are copied and modified to create new characters. This allows high-quality character generation without manual modeling from scratch, resolving the contradiction between character quality and production speed by reusing validated template structures.
Solution Approach 2:
Character templates are prepared in advance with pre-modeled features and structures. The system performs preliminary actions by pre-processing character designs into reusable templates, enabling rapid generation of new characters through template instantiation and modification rather than manual creation.
2Ease of operation
If a limited set of pre-defined avatars is provided, then ease of use is improved, but adaptability and creativity are reduced
Solution Approach 1:
The system provides a dynamic interface where users can interactively adjust template parameters such as facial features, body type, and clothing styles. This dynamic modification capability allows users to customize characters within a user-friendly framework, maintaining ease of operation while significantly enhancing adaptability and character diversity.
Solution Approach 2:
The avatar system is segmented into independent modifiable components such as face, body, limbs, and accessories. Each component can be independently adjusted through the user interface, allowing flexible customization while maintaining a simple operational structure. This segmentation enables users to create diverse characters by combining different components without complexity.
3Manufacturing precision
If high resolution modeling is applied to all characters, then character quality is improved, but production cost increases linearly with character number
Solution Approach 1:
The system applies different levels of detail to different character components based on needs. Critical features like facial expressions and key body parts maintain high resolution from templates, while less critical areas use simplified representations. This local quality approach maintains necessary character quality without the linear cost increase of uniform high-resolution modeling for all characters.

AI summary
The generation of characters within computer animations is a labor intensive and expensive activity. Whereas prior art approaches have sought to reduce this loading by providing reference avatars, these do not fundamentally overcome the intensive steps in generating these reference avatars, and they provide limited variations to the businesses employing them. Accordingly the invention provides the user with a simple and intuitive mechanism to affect the weightings applied in establishing the physical characteristics of an avatar generated using an inheritance based avatar generator. The inheritance based generator allowing, for example, the user to select a first generation of four grandparents, affect the weightings in generating the second generation parents, and subsequently affect the weightings in generating the third generation off-spring avatar from these parents, therein providing a wide range of avatars from an initially limited set of avatars. Accordingly the invention provides animators with a means of rapidly generating and refining the off-spring avatar to provide the character for their animated audio-visual content.
