Solution Overview

Problem

Existing methods for rendering graphical scenes lack efficiency in generating realistic environments, particularly in optimizing the efficiency of the scene generation, and the use of neural networks to identify locations for objects within these scenes, which can be memory and resource-intensive.

Innovation Solution

Utilizing a scene generator that employs neural networks to generate scene graphs, analyze spatial relationships, and execute object placement, reducing resource utilization through generative AI techniques and efficient object generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional rendering techniques are used to generate graphical scenes, then scene generation can be performed, but significant memory, time, and computing resources are consumed

Engineering Contradiction:
Improvescene generation speedVSAvoidcomputing resources
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent segments the scene generation process into distinct components: neural network-based location identification, object placement determination, and graphical scene generation. By dividing the rendering process into these modular stages, the system can optimize resource allocation at each step, reducing overall computing resource consumption while maintaining generation speed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary actions by using neural networks to pre-identify object locations and determine placement decisions before actual scene rendering. This preliminary analysis phase separates computationally intensive identification tasks from the rendering phase, allowing for more efficient resource utilization during the actual scene generation process.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If neural networks are used to identify object locations in graphical scenes, then accurate placement can be achieved, but memory and computing resources increase significantly

Engineering Contradiction:
Improvelocation identification accuracyVSAvoidmemory resources
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent introduces an intermediary scene graph structure that mediates between the neural network's location identification and the final graphical scene. The scene graph serves as a lightweight intermediate representation that stores only essential spatial relationships and object placements, significantly reducing memory requirements compared to storing complete scene data while maintaining location identification accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts only the essential spatial information and object placement data from the neural network's comprehensive analysis. By taking out and storing only the critical location identifiers and placement decisions in the scene graph, the system maintains high measurement precision while minimizing memory resource consumption.

Inventive Principle:
Principle #2Taking out (Extraction)
