Render Graph Multiplexer Instancing for Crowd Rendering Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for rendering computer-generated animations involving large crowds of similar objects are inefficient, as they require time-consuming individual configuration of light setups and duplication of materials and textures, leading to data management issues.
Innovation Solution
A dependency graph system with interconnected nodes, including supplier nodes, a multiplexer node, and graphlet nodes, allows for the generation and instancing of graphlets for each supplier node, enabling efficient rendering of images by sharing and duplicating visual effects like lighting rigs across multiple objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual light setups and materials are manually configured for each object in a crowd, then visual quality and realism are improved, but time consumption and data management complexity increase significantly
Solution Approach 1:
The patent segments the crowd rendering process into two distinct levels: a master graph that defines the visual effect configuration once, and multiple slave graphs that automatically instance the effect for each object. This segmentation allows the lighting rig to be configured individually for visual quality while automatically applied to all objects, eliminating manual repetition and reducing time consumption.
Solution Approach 2:
The patent implements an instancing mechanism where the lighting rig defined in the master graph is copied and applied to multiple slave graphs simultaneously. This copying approach preserves the visual quality of individually configured light setups while dramatically reducing the time required to set up crowds, as the same configuration is automatically replicated across all objects rather than manually created for each one.
2Manufacturing precision
If individual light setups are manually configured for each object in a crowd, then visual quality is improved, but device complexity and data management burden increase
Solution Approach 1:
The patent merges the configuration management into a single master graph that controls all slave graphs. Instead of managing individual light setups for each object, the lighting rig is defined once in the master graph and automatically distributed to all slave graphs. This merging reduces data management complexity while preserving visual quality, as changes to the master graph automatically update all instances.
Solution Approach 2:
The master graph serves multiple functions simultaneously: it defines the visual effect configuration, manages the instancing process, and controls all slave graphs. This universal approach allows a single configuration to serve the entire crowd, reducing the complexity burden of managing individual setups for each object while maintaining high visual quality standards.
3Manufacturing precision
If visual effects are individually configured for each object, then rendering quality is improved, but productivity and efficiency decrease
Solution Approach 1:
The patent performs preliminary configuration in the master graph, where the lighting rig and visual effects are defined once before being automatically applied to all slave graphs. This preliminary action ensures high rendering quality through careful configuration while dramatically improving productivity, as the setup work is performed once rather than repeated for each object in the crowd.
Solution Approach 2:
The instancing mechanism copies the master graph configuration to all slave graphs automatically. This copying process preserves the high rendering quality of individually configured effects while boosting productivity, as the configuration is replicated instantly across all objects rather than requiring manual setup for each one, thus enhancing overall rendering efficiency.
