3D Model Billboard Rendering for Automatic Dot Picture Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual creation of dot pictures for characters and field spaces in video games is labor-intensive and burdensome as the volume of the game or number of characters increases, necessitating an automated solution.
Innovation Solution
An information processing program and apparatus that automatically generates dot pictures by determining target objects in a three-dimensional virtual space, converting them into two-dimensional image data, and attaching them to a billboard facing the virtual camera, allowing for the display of dot pictures instead of three-dimensional models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual creation of dot pictures is used for each character and posture, then the quality and customization of dot pictures is improved, but the work量和 time consumption increases significantly
Solution Approach 1:
The patent uses automated rendering to generate dot pictures by copying the visual appearance of three-dimensional models. The system renders 3D models and converts them into two-dimensional dot pictures through image processing, eliminating the need for manual drawing while maintaining visual quality and customization for each character and posture.
Solution Approach 2:
The patent replaces the manual mechanical process of drawing dot pictures with an automated computational system. The system uses rendering engines and image processing algorithms to automatically generate dot pictures from three-dimensional models, substituting human artists with automated mechanical processes.
2Adaptability or versatility
If the number of characters and postures increases, then the game content and versatility improve, but the manual creation burden increases proportionally
Solution Approach 1:
The system automatically generates dot pictures by copying the visual properties of three-dimensional models. When new characters or postures are added to the game, the system can automatically render and convert their 3D models into dot pictures, maintaining consistency with existing art style without requiring manual creation for each new element.
Solution Approach 2:
The system changes the parameter of dot picture generation from manual creation to automated rendering. By adjusting rendering parameters and image processing settings, the system can efficiently generate dot pictures for a large number of characters and postures while maintaining consistent quality and style throughout the game.
3Manufacturing precision
If three-dimensional models are used instead of dot pictures, then the rendering quality and detail level improve, but the nostalgic aesthetic and artistic style are lost
Solution Approach 1:
The patent applies color and style transformations to rendered images to achieve the desired dot picture aesthetic. The system processes rendered images by adjusting color information, applying dot patterns, and modifying visual properties to transform realistic three-dimensional renders into stylized two-dimensional dot pictures that maintain nostalgic artistic style while benefiting from 3D rendering detail.

AI summary
An information processing system generates a display image by rendering a 3D virtual space in which one or more 3D models are arranged at a viewpoint of a virtual camera, determines a target object from the 3D models, renders only the target object at the viewpoint of the virtual camera to convert the target object into 2D image data, generates a plurality of dot pictures by making an inside of each dot uniform color information based on a predetermined rule, the 2D image data including a plurality of neighboring pixels as one dot, and displays the dot pictures instead of the 3D models in the 3D virtual space by attaching the dot pictures to a billboard set as an image attachable area which always faces the virtual camera in the 3D virtual space with respect to a position where the target object is arranged in the 3D virtual space.
