Text to Performance Pipeline for NPC Scene Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video game technologies face challenges in efficiently generating and updating interactive non-player character (NPC) scenes within a computer game environment, particularly in responding to changes in scripts and digital assets, which affects the realism and immersion of the gaming experience.
Innovation Solution
A text-to-performance pipeline system that detects changes in scripts and digital assets, generates corresponding NPC data, processes it with an NPC rig, determines camera locations, and outputs data for a game development engine to create interactive NPC scenes, incorporating vocal, facial, and body digital assets, and camera framing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual generation and updating of NPC scenes is used, then quality control and creativity can be maintained, but productivity and response time to script changes are reduced
Solution Approach 1:
The system divides the NPC scene generation process into distinct segments: script change detection, NPC data generation, rig processing, camera solver, and asset retrieval. Each segment handles a specific task independently, allowing automated processing while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The system introduces intermediary components such as the rig system and camera solver that mediate between the script data and final NPC scene output. These intermediaries automatically process and transform data through standardized pipelines, enabling high-speed generation without requiring direct manual control at each stage.
2Speed
If real-time automatic updates are implemented, then responsiveness to script changes is improved, but system complexity and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-configuring the rig systems, asset libraries, and processing pipelines before actual NPC scene generation is needed. This setup allows the system to respond instantly to script changes without requiring complex real-time computations, as the infrastructure is already in place and optimized.
Solution Approach 2:
The system replaces manual mechanical processes with automated digital processing. Instead of manually generating and updating NPC scenes, the system uses computer-based automation including script parsing, automatic asset retrieval, and digital rendering, significantly reducing response time while managing complexity through software-based solutions.
3Reliability
If comprehensive digital asset integration is used, then realism and immersion of NPC scenes are enhanced, but device complexity and data management requirements increase
Solution Approach 1:
The system employs a universal asset management framework that handles multiple types of digital assets (vocals, facial animations, body movements, camera data) through a single integrated pipeline. The rig system serves multiple functions simultaneously, managing different asset types and applying them to NPC models, thereby reducing overall system complexity despite comprehensive integration.
Solution Approach 2:
The system implements a nested structure where digital assets are organized in hierarchical layers: base NPC models, facial animation layers, body animation layers, and vocal layers. This nesting allows comprehensive asset integration while maintaining manageable complexity, as each layer can be independently managed and applied to the base model without interfering with other layers.
Data Source
AI summary
Methods, apparatus and systems are provided for generating an interactive non-player character (NPC) scene for a computer game environment of a video game. Changes are detected in relation to a script associated with the interactive NPC scene. For each NPC, a set of NPC data associated with the interactions said each NPC has within the script is generated corresponding to the changes. The generated set of NPC data is processed with an NPC rig associated with said each NPC to generate an NPC asset. A camera solver is applied to a region of the computer game environment associated with the script for determining locations of NPC assets and one or more cameras within said region in relation to said interactive NPC scene. Data representative of said each NPC asset and said determined NPC asset and camera locations for use by a game development engine for generating said interactive NPC scene.
