Look-Selector Node Dependency Graph Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer-generated animation, managing consistent lighting conditions for animated characters with multiple visual appearances is challenging due to redundant lighting setups and increased complexity, as each visual appearance requires separate lighting configurations.
Innovation Solution
A computer-implemented method using a dependency graph with a look-selector node to select and apply a single active look for a computer-generated object, allowing the same lighting configuration to be reused across different visual appearances, thereby simplifying the rendering process and reducing redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate lighting setups are created for each visual appearance, then each look can be rendered independently, but the complexity of managing lighting configurations increases and redundancy occurs
Solution Approach 1:
The patent creates a single lighting configuration that serves multiple visual appearances (looks) of the same character. Instead of creating separate lighting setups for each look, the system allows one lighting configuration to be universally applied across different visual representations, reducing management complexity while maintaining rendering flexibility
Solution Approach 2:
The patent merges the lighting configuration management for multiple looks into a unified system. By combining the lighting setup into a single shared configuration that can be applied to different visual appearances, the system eliminates redundant lighting setups and simplifies the overall management structure
2Ease of operation
If separate lighting setups are created for each visual appearance, then each look has dedicated lighting control, but redundant lighting setups increase processing overhead
Solution Approach 1:
The lighting configuration is designed to be multi-functional, serving multiple visual appearances simultaneously. This universal lighting setup maintains ease of control while eliminating the redundant processing that would occur with separate lighting setups for each look, thereby improving rendering efficiency
3Manufacturing precision
If visual effects are reapplied for every change of visual appearance, then each look receives optimized visual effects, but the rendering process becomes slower and more resource-intensive
Solution Approach 1:
The lighting configuration is established in advance as a universal setup that can be applied to multiple visual appearances. This preliminary creation of a shared lighting configuration eliminates the need to reapply visual effects for every look change, maintaining quality while significantly reducing rendering time and computational resources

AI summary
A system and method for computing a rendered image of a computer-generated object in a computer-generated scene. A dependency graph is accessed, the dependency graph including a plurality of interconnected nodes including a look-selector node. An asset is accessed at an input to the look-selector node. The asset includes a plurality of looks for the computer- generated object, each look of the plurality of looks corresponding to a different visual appearance of the computer-generated object. At the look-selector node, an active look is selected from the plurality of looks. The active look is passed to a next node of the dependency graph. The rendered image of the computer-generated object is computed having a visual appearance that corresponds to the active look.
