3D Image Processing View Volume Deformation for Aiming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional image processing systems in video games make it difficult for players to recognize and interact with virtual spaces due to complex operations required for aiming and shooting, as the gun sight movement is not intuitive and can lead to missed targets.
Innovation Solution
A three-dimensional image processing program that uses a virtual camera to output imaged images, allowing for easy recognition of virtual spaces by detecting operation inputs, moving objects within the space, setting a gazing point and view volume, and deforming the view volume to keep the gazing point aligned with the vanishing point, simplifying the display and interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gun sight movement is controlled in accordance with the movement of the player object, then the player can perform attacking operations, but the operation becomes complex and difficult
Solution Approach 1:
The patent extracts the gun sight control from the player object movement control. Instead of requiring simultaneous control of both player object and gun sight, the gun sight is independently controlled by a separate input (e.g., right stick for character movement, left stick for gun sight aiming), simplifying the operation while maintaining attacking capability
Solution Approach 2:
The control system is segmented into independent control modules: player object movement control and gun sight control. This segmentation allows each control function to be operated separately, reducing the complexity of simultaneous operations while preserving the ability to perform attacking operations
2Loss of information
If the gun sight is arranged between the player object and the vanishing point, then the three-dimensional space can be visualized, but the player sometimes fails in shooting the aimed enemy object
Solution Approach 1:
The patent introduces a separate aiming indicator (independent from the gun sight position) that directly shows the shooting direction toward the enemy object. This intermediary indicator mediates between the player's aiming intention and the actual shooting direction, ensuring accurate targeting while the gun sight remains positioned for three-dimensional space visualization
3Adaptability or versatility
If the player has to simultaneously perform moving operation of the player object and moving operation of the gun sight, then the game can be played, but it causes a problem of complex and difficult operation
Solution Approach 1:
The patent implements multi-functionality in the control system where different input devices handle different functions: one controller handles player object movement while another handles gun sight aiming. This universal control approach allows the system to perform multiple functions (movement and aiming) simultaneously through separate, simplified controls rather than requiring complex coordinated operations

AI summary
A game apparatus functioning as a three-dimensional image processing apparatus includes a CPU. The CPU executes three-dimensional image processing. When a cursor on a display screen is moved according to an instruction from a user, a gazing point is also moved acceding thereto. At this time, a view volume (cone) is deformed such that a gazing point plane is maintained at an original position. Thus, the gazing point and a vanishing point are overlapped with each other on the display screen.
