3D Game Map Generation via Unified Polygon Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game systems require separate storage for 3D virtual space and 2D map data, leading to increased storage and memory requirements, especially when multiple 3D virtual spaces are involved.
Innovation Solution
An image processing program that uses a single 3D virtual space to generate both main and map images by employing multiple polygons with attributes and textures, allowing for the generation of map images without the need for separate map data, thereby reducing storage and memory usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate data for configuring 3-dimensional virtual space and 2-dimensional map are stored, then the map image can be displayed, but the storage space of storage medium and memory increases
Solution Approach 1:
The patent merges the storage of map data and game space data into a single data structure. By using one polygon for both map representation and 3D game space rendering, the system eliminates redundant separate storage requirements, directly reducing storage space while maintaining map display functionality
Solution Approach 2:
The patent makes polygons serve multiple functions simultaneously. The same polygon data structure is used both for generating 2D map images and for configuring 3D virtual game spaces, allowing one data element to fulfill multiple purposes and eliminating the need for separate dedicated map data storage
2Reliability
If separate data for configuring 3-dimensional virtual space and 2-dimensional map are stored, then the map image can be displayed, but the size of memory for temporarily storing data increases
Solution Approach 1:
The patent combines map data and game space data into a unified storage structure. By using the same polygon data for both map rendering and 3D game environment, the system reduces the total memory footprint required to temporarily store both types of data simultaneously
Solution Approach 2:
The patent enables polygons to perform dual functions as both map elements and 3D game objects. This multi-functionality allows the system to use the same memory space for both map display and game rendering, eliminating the need for separate memory allocations
3Adaptability or versatility
If data of 2-dimensional maps corresponding to respective 3-dimensional virtual spaces are prepared, then map images for multiple game stages can be displayed, but the storage space of storage medium and memory increases
Solution Approach 1:
The patent creates a universal polygon data structure that can represent both 2D map features and 3D game space elements. This universal representation allows the same data to be used across multiple game stages and for both map and game rendering, eliminating the need to prepare separate 2D map data for each 3D virtual space
Solution Approach 2:
The patent merges the concept of separate 2D map data and 3D game space data into a single integrated data model. By using polygons that simultaneously define both map boundaries and 3D terrain, the system achieves multi-game stage support without proportionally increasing storage requirements

AI summary
A plurality of polygons are placed in a 3-dimensional virtual space. Each of plural types of first textures corresponding to plural types of attributes which the plurality of polygons have is mapped to the polygon that has the attribute of the type corresponding to the first texture, the 3-dimensional virtual space is shot by a first virtual camera, and thereby a main image is generated. In addition, each of the plural types of second textures corresponding to plural types of attributes which the plurality of polygons have is mapped to the polygon that has the attribute of the type corresponding to the second texture, the 3-dimensional virtual space is shot by a second virtual camera, and thereby a main image is generated.
