Texture Mapping Timing Control via CG Attribute Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the field of computer graphics (CG) production, it is challenging to simultaneously perform texture mapping operations while viewing the image being mapped, especially when switching between moving images, as the timing of image switching during live broadcasting operations is difficult to match with the animation's predetermined timing and speed.
Innovation Solution
An image processing apparatus is designed with an image selection unit, image generation unit, image mapping unit, and image selection control unit, which allows for easy designation of switching timing by controlling image data selection based on attributes within the CG description data, enabling precise timing of texture mapping during CG production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual manipulation of image selection unit is used for switching moving images, then the operation is flexible, but the timing cannot be matched with predetermined CG animation timing
Solution Approach 1:
The invention stores switching timing information in advance within the CG description data during the CG production phase. This preliminary action allows the system to automatically retrieve and execute the stored timing information during live broadcasting, eliminating the need for manual timing adjustments while maintaining precise synchronization with the animation.
2Ease of operation
If image switching is performed manually during operation, then real-time control is possible, but the proceeding speed changes make timing matching difficult
Solution Approach 1:
The system automatically controls image switching based on stored timing information from CG description data, creating a closed-loop system where the switching timing is determined by pre-analyzed animation characteristics. This feedback mechanism ensures consistent timing synchronization regardless of variations in animation playback speed.
3Adaptability or versatility
If texture mapping is performed with multiple input images, then the animation richness is improved, but the switching timing coordination becomes complex
Solution Approach 1:
The invention divides the complex switching coordination task into separate, manageable components by storing switching timing information for each input image independently in the CG description data. This segmentation allows the system to handle multiple images systematically, reducing coordination complexity while maintaining animation richness.
