Tree-Based In-Place Pathfinding for Visual Object Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional graphics editing systems face challenges in accurately applying sets of graphics operations to multiple visual objects, often resulting in erroneous outputs and requiring excessive manual interactions to achieve the desired visual results.
Innovation Solution
A tree-based in-place mechanism for pathfinding operations is employed, where a tree structure is generated with nodes representing visual objects and groups, allowing for accurate traversal and application of graphics operations using depth-first search traversal, ensuring correct hierarchical relationships and ordering of operations.

1Reliability
If conventional graphics editing systems apply sets of graphics operations to multiple visual objects, then the operations are performed, but the systems produce erroneous results and require excessive manual interactions
Solution Approach 1:
The patent segments the set of visual objects into a tree structure where the root node represents a group of visual objects and child nodes represent individual visual objects or subgroups. This hierarchical segmentation enables systematic traversal and application of graphics operations to subsets of visual objects in a controlled manner, preventing erroneous results while reducing manual interactions.
Solution Approach 2:
The patent performs preliminary actions by generating the tree structure and determining the traversal order before applying graphics operations. The system pre-establishes the hierarchical relationships and operation sequences, which ensures that operations are applied correctly without requiring excessive manual correction during the actual operation execution.
2Manufacturing precision
If a tree structure is generated and traversed to apply pathfinding operations to visual objects, then the accuracy of graphical editing is improved, but the system complexity increases
Solution Approach 1:
The patent introduces a tree structure as an intermediary data structure between the input visual objects and the graphics operations. This intermediary organizes visual objects hierarchically and guides the application of operations through systematic traversal, improving accuracy while managing complexity through a well-defined intermediate representation rather than direct complex processing.
Solution Approach 2:
The tree structure serves multiple functions: it organizes visual objects hierarchically, determines traversal order, identifies subsets for operations, and maintains relationships between parent and child nodes. This multi-functionality reduces the need for separate mechanisms for each task, thereby managing system complexity while improving manufacturing precision.

AI summary
Techniques are described for tree based in-place mechanism for pathfinding operations. In implementations, indications of a set of visual objects and pathfinding operations to be applied to the visual objects is received. Accordingly, a tree object (e.g., a tree structure) is generated and populated with nodes that represent individual visual objects and/or groups of visual objects. The tree object is traversed and pathfinding operations are applied to subsets of the visual objects based on their respective arrangement in the tree structure. For instance, the tree object is traversed according to a depth first search traversal where pathfinding operations are applied to subsets of visual object nodes to generate operation results. Further, subsets of the operation results become input to further pathfinding operations with additional visual objects until a final operation result is output. The final operation result is rendered and output, such as for display.
