Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional graphic object modification techniques struggle to render real-time modifications of complex and numerous graphic objects due to high computational resource consumption and performance lag, especially when dealing with large numbers of graphic objects.
Innovation Solution
A graphic object modification system that identifies stroke and fill values for multiple graphic objects, writes them to a buffer in separate passes to prevent overwriting, and uses z-order positioning to cluster objects for efficient rendering, allowing real-time display of modifications while minimizing resource usage.

Engineering Contradiction Analysis
1Speed
If conventional vector graphics engines are used to perform basic graphic object transformations, then the transformations can be completed, but the processing time is excessive and real-time rendering is not achieved
Solution Approach 1:
The patent segments the graphic object data into separate stroke and fill components, processing them independently through separate rendering passes. This segmentation allows the system to optimize processing for each component type and avoid redundant calculations, significantly improving transformation speed and enabling real-time rendering performance.
Solution Approach 2:
The patent creates alternate representations (copies) of graphic objects in a different data format optimized for rapid transformation. Instead of repeatedly processing the original complex vector data, the system works with these pre-processed copies during transformation operations, dramatically reducing processing time while maintaining visual fidelity.
2Adaptability or versatility
If numerous and complex graphic objects are modified simultaneously, then comprehensive editing capability is achieved, but computational resource consumption increases exponentially
Solution Approach 1:
The patent merges multiple graphic objects into a single composite rendering context while maintaining individual object identities. By combining the rendering of multiple objects into unified stroke and fill passes, the system processes numerous objects simultaneously rather than individually, reducing computational resource consumption from exponential to linear scaling.
Solution Approach 2:
The patent performs preliminary processing of graphic objects by pre-calculating and storing alternate representations before transformation operations. This preliminary action includes pre-segmenting objects into stroke and fill components and pre-computing transformation parameters, so that actual transformation operations require minimal real-time computation even when handling numerous complex objects.
3Device complexity
If stroke and fill values are written to the same buffer simultaneously, then rendering process is simplified, but data overwriting occurs causing rendering errors
Solution Approach 1:
The patent segments the rendering process into distinct stroke and fill passes, with each pass writing to separate regions or using separate buffer instances. This segmentation prevents data overwriting by ensuring that stroke data and fill data are processed independently in sequence, maintaining rendering accuracy while keeping the overall process manageable through systematic separation of concerns.
4Measurement precision
If graphic objects are re-drawn at each stage of modification, then accurate representation is maintained, but processing time increases preventing real-time display
Solution Approach 1:
The patent creates and works with alternate representations of graphic objects that are optimized for transformation operations. These copies maintain the essential visual and geometric properties needed for accurate representation while being structured to allow rapid mathematical transformation. The system transforms these copies in real-time and only performs full re-drawing of the original objects after transformation is complete, enabling real-time display with maintained accuracy.

AI summary
Transformation of graphic objects is described. A graphic object modification system receives an indication of a transformation to be performed on one or more graphic objects. For merger transformations, a stroke and a fill are identified for each graphic object being merged. Fill values are written to a buffer in a first pass, and stroke values are written to the buffer in a second pass without overwriting fill values. The merged graphic object is then output by rendering values stored in the buffer. For other non-merger transformations, z-order information is identified for each displayed graphic object. Graphic objects selected for transformation are allocated into clusters based on their z-order information. Clusters are rendered in separate GPU textures and transformations are applied to the separate textures, enabling the graphic object modification system to output transformation results in real-time without re-rendering the actual graphic objects being transformed.
