Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of modern video games requires significant computing resources for testing and rendering large virtual environments, leading to inefficiencies and increased development time due to repeated spatial partitioning and quadtree creation processes.
Innovation Solution
A system that performs spatial partitioning and reverse tree generation, allowing new zones to be added to the virtual environment without rebuilding the entire tree structure, using a reverse quadtree that starts from a leaf node and expands to the root, enabling real-time updates and reduced resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spatial partitioning and quadtree creation are performed repeatedly during development and testing, then the virtual environment can be modified and tested, but computing resources and time are significantly consumed
Solution Approach 1:
The patent segments the quadtree structure into modifiable components that can be updated independently. Instead of recreating the entire quadtree, the system divides the update process into selective node modifications, allowing partial updates of the spatial partitioning structure based on changed zones in the virtual environment.
Solution Approach 2:
The patent implements a dynamic quadtree system that can adapt its structure in real-time during gameplay and development. The spatial partitioning structure transitions from a static pre-built tree to a dynamic structure that automatically reconfigures itself when zones are added, removed, or modified, maintaining optimization without requiring full reconstruction.
2Reliability
If the entire quadtree is rebuilt when new zones are added, then the spatial partitioning remains optimal, but computing resources are wasted
Solution Approach 1:
The patent extracts only the necessary portions of the quadtree that need updating when zones change. Instead of processing the entire tree structure, the system identifies and updates only the affected nodes and sub-trees, separating the update operation from a full reconstruction and thereby reducing computational energy consumption.
Solution Approach 2:
The patent changes the operational parameters of the quadtree from a static, all-or-nothing reconstruction model to a dynamic, partial-update model. The system adjusts the structure based on specific zone modifications, changing parameters such as node depth, partition boundaries, and tree balance only where necessary to maintain optimality while conserving resources.
3Measurement precision
If complex spatial partitioning is performed for large virtual environments, then rendering accuracy is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary spatial partitioning during the development phase to establish an optimized quadtree structure before gameplay begins. This pre-computation allows the system to maintain high rendering accuracy during gameplay by leveraging the pre-established spatial relationships, reducing the need for complex real-time calculations.
Solution Approach 2:
The patent maintains continuous optimization of the spatial partitioning structure by implementing incremental updates that preserve rendering accuracy. The system continuously adapts the quadtree to reflect current zone configurations without interrupting gameplay or requiring full re-partitioning, ensuring both accuracy and speed are maintained throughout the game lifecycle.
Data Source
AI summary
An improved virtual environment creation and testing process can be achieved by a combination of spatial partitioning and reverse tree generation. The reverse tree may be representative of the virtual environment and may be generated starting from a smallest portion or zone of the virtual environment (represented as a leaf node) and expanding up towards a root node representative of the entire virtual environment. Advantageously, the system can add new zones to the virtual environment and representative tree data structure that are external to the existing virtual environment without generating a new tree data structure. Thus, the computing resources utilized by the system disclosed herein may be significantly reduced compared to existing processes while improving the flexibility of the spatial partitioning and tree generation process thereby enabling spatial partitioning to be performed in real or near real time as a developer authors the virtual environment.
