Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of designing and maintaining animation rigs for 3D computer animations requires specialized knowledge in graphical arts and mathematics, limiting the process to a select few and making it difficult to share rig pieces across different projects and industries.
Innovation Solution
A method and system for generating animation rigs using simplified block elements, where each block represents a rig element and can be interconnected to form a composite rig, with a 2D interface abstracting away underlying complexities, allowing users to connect blocks visually and export the rig to a 3D environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional rigging methods are used, then rig functionality and control precision are maintained, but the complexity of the design process increases and limits accessibility to specialized experts only
Solution Approach 1:
The rigging system is divided into modular blocks, each representing a specific rig element (joint, control, constraint). These blocks can be independently selected, configured, and connected, transforming a monolithic complex process into manageable discrete units that non-experts can assemble.
Solution Approach 2:
A simplified user interface acts as an intermediary between the user and the complex underlying rigging mathematics. The interface presents visual block representations and connection mechanisms that abstract away the complex 3D scene graph interactions, allowing users to work with intuitive visual metaphors rather than mathematical transformations.
2Ease of operation
If simplified block-based interface is used, then ease of operation and accessibility are improved, but the underlying mathematical precision and graphical transformation control may be compromised
Solution Approach 1:
The system creates a simplified visual copy or representation of the actual rigging structure. The blocks and connections in the interface are graphical abstractions that map to precise mathematical definitions in the underlying 3D environment. This copying mechanism allows users to work with simplified representations while maintaining fidelity to the precise underlying model.
Solution Approach 2:
The direct manipulation of complex mathematical transformations is replaced with a visual block-based system. Instead of manually adjusting transformation matrices and scene graph parameters, users interact with visual blocks that encapsulate these mathematical operations, substituting a mechanical/mathematical system with a visual interface system that achieves the same end result.
3Adaptability or versatility
If custom rig designs are created from scratch, then specific project requirements are met, but the time and resources required increase significantly
Solution Approach 1:
Common rig elements and configurations are pre-packaged into reusable blocks that have been previously designed and tested. Users can select from these pre-prepared blocks (such as standard joint types, control structures, and constraints) and combine them to create custom rigs, eliminating the need to design every element from scratch while maintaining project-specific customization.
4Reliability
If rig pieces are developed in isolation, then individual rig elements can be optimized, but sharing and reusing rig components across different projects becomes difficult
Solution Approach 1:
The block-based system creates universal building blocks that can serve multiple functions across different projects and rig types. A single block representing a joint or control element can be used in various contexts (different characters, objects, or scenes) by simply connecting it to different other blocks, making rig components truly reusable and adaptable across diverse applications.

AI summary
A method of generating an animation rig for a three-dimensional (3-D) computing environment may include providing a rig generation environment that includes a library storing a plurality of blocks. Each of the plurality of blocks may represent particular rig elements and include information for generating the rig elements in the 3-D computing environment along with a first icon that is visually representative of the particular rig elements. The method may also include receiving and displaying two or more blocks in the rig generation environment, and receiving one or more graphical connections between the blocks. The method may additionally include generating the animation rig using the information of each of the two or more blocks and sending the animation rig from the rig generation environment to the 3-D computing environment.
