Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for optimizing virtual environment content generation are inefficient, particularly in reducing processing power requirements for immersive VR content, as they often rely on labor-intensive and limited optimization techniques such as brute force vertex culling, which are not suitable for widespread application.
Innovation Solution
A machine learning-based approach using a reinforcement learning agent is employed to efficiently cull vertices in virtual environments by training the agent to navigate and identify geometry, optimizing the content representation by reducing unnecessary data and improving rendering speed.

Engineering Contradiction Analysis
1Productivity
If traditional brute force optimization methods are used to cull vertices in virtual environments, then some optimization is achieved, but the process becomes labor-intensive and time-consuming with limited optimization results
Solution Approach 1:
The patent replaces traditional mechanical brute force optimization methods with a machine learning-based system. A trained machine learning model automatically analyzes virtual environment data, identifies visible geometry, and determines which vertices to cull, substituting manual or simple algorithmic approaches with an intelligent system that learns from training data to make optimization decisions efficiently
Solution Approach 2:
The machine learning model performs self-service by autonomously navigating the virtual environment, identifying visible geometry, and determining culling decisions without human intervention. The system trains on virtual environment data and then independently applies this knowledge to optimize content generation, making the optimization process self-sufficient and automated
2Manufacturing precision
If high-quality immersive VR content is generated with detailed geometry, then content quality is improved, but processing power requirements increase significantly
Solution Approach 1:
The patent extracts and removes unnecessary geometry from virtual environments by using a machine learning model to identify visible geometry and cull invisible vertices. This extraction process removes redundant data that does not contribute to visual quality, thereby reducing processing power requirements while maintaining the quality of visible content
Solution Approach 2:
The patent applies local quality optimization by maintaining high geometric detail only in regions visible to the camera while reducing or removing detail in invisible regions. The machine learning model determines visibility on a local basis for different parts of the virtual environment, allowing high-quality representation where needed and efficient culling where not needed
3Reliability
If comprehensive geometry is retained in virtual environments to ensure all objects are visible, then content completeness is maintained, but data size and processing requirements increase
Solution Approach 1:
The patent uses feedback mechanisms where the machine learning model is trained on virtual environment data including camera positions and visible geometry. The model learns from this feedback what geometry is actually visible and uses this knowledge to make accurate culling decisions, ensuring that visible geometry is preserved while invisible geometry is removed
