Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sound generation processing in virtual spaces for games requires high-level tool functions and complex calculations for complicated sound sources, leading to increased programmer workload and processing slowdowns.
Innovation Solution
A sound generation processing apparatus that uses simple shapes like cubes, cylinders, and cones to create sound sources with the same identifiers, allowing for efficient sound field configuration and reduced processing load by handling these shapes separately and combining them to simulate complex sound sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound sources with complicated shapes are placed in virtual space to match land configuration, then sound field realism is improved, but processing load increases and processing speed decreases
Solution Approach 1:
The patent divides complicated sound sources into multiple simple-shaped sound sources (cubes, spheres, cylinders) that can be independently processed. Each simple sound source is assigned a unique identifier, allowing the system to handle them separately through efficient geometric calculations rather than processing complex unified shapes.
Solution Approach 2:
The patent uses simple geometric shapes (cube, sphere, cylinder) as standardized templates to represent sound sources instead of creating and processing complex custom shapes. These standardized forms enable efficient distance calculations and acoustic processing while maintaining visual and functional realism.
2Manufacturing precision
If complicated shape sound sources are used to match land configuration, then sound field accuracy is improved, but programmer workload and tool complexity increase
Solution Approach 1:
The system segments complicated sound sources into assemblies of simple geometric primitives. This segmentation allows standard tools to handle each component independently, eliminating the need for complex tool functions while maintaining the ability to represent accurate sound fields through multiple simple sources.
Solution Approach 2:
The patent changes the representation parameters from complex shape definitions to simple geometric parameters (position, size, type) for each sound source. This parameter simplification reduces tool complexity while preserving sound field accuracy through the collective behavior of multiple simple sources.
3Productivity
If multiple sound sources with same identifiers are handled separately, then processing efficiency is improved, but sound continuity may be affected
Solution Approach 1:
The system implements feedback mechanisms that monitor the identifiers of sound sources across processing frames. When multiple sound sources share the same identifier, the system detects this condition and applies continuity maintenance processing to ensure smooth transitions and prevent audible interruptions, while still benefiting from the processing efficiency of handling them as separate entities.

AI summary
The prevent invention improves a processing speed by combining simple sound source species with a basic configuration and processing the combination as a single sound source, when sound sources and sound fields are placed and formed in a three-dimensional virtual space. As a sound source object that corresponds to a river 21, a sound source object 21x with a complicated shape that includes sound source objects 21a, 21c and 21e with shapes of rectangular parallelepipeds and sound source objects 21b and 21d with shapes of triangular prisms are placed. The sound source objects 21a to 21e have the same identification numbers and have sound data related to a babbling sound of the river. In a case where the sound source object 21c is the closest to a player character, sound generation processing is executed based on the sound source object 21c.
