Engineering Contradiction Analysis
1Measurement precision
If three-dimensional calculation is performed to determine virtual camera movement rate, then movement accuracy is improved, but processing load is increased
Solution Approach 1:
The patent creates a two-dimensional copy of the three-dimensional game space by generating a flattened image representing the game space. The virtual camera's sight point position is projected onto this two-dimensional image, and movement rate is calculated based on two-dimensional pixel distances rather than three-dimensional coordinate calculations. This copying approach maintains calculation accuracy while significantly reducing processing complexity.
Solution Approach 2:
The patent transforms the problem from three-dimensional space to two-dimensional space by flattening the game space into a two-dimensional image representation. Instead of calculating distances and movement rates in three-dimensional coordinates, the system performs calculations on the two-dimensional pixel grid, reducing computational complexity while preserving the essential spatial relationships needed for accurate camera movement.
