Solution Overview
Problem
Deforming three-dimensional objects in virtual spaces is complex due to the need to consider both surface and internal structures, leading to increased processing requirements and manual skeleton model creation.
Innovation Solution

Engineering Contradiction Analysis
1Manufacturing precision
If three-dimensional object deformation is performed by considering internal structure, then deformation naturalness is improved, but processing complexity and arithmetic processing amount increase
Solution Approach 1:
The patent creates a simplified copy of the three-dimensional object by projecting it onto multiple two-dimensional planes. This projected copy is then deformed independently, avoiding the need to consider the complex internal structure of the original 3D object. The deformation is transferred back to the original object, achieving natural-looking deformation without the computational complexity of physical simulation or skeleton-based approaches.
Solution Approach 2:
The patent transforms the three-dimensional deformation problem into a series of two-dimensional problems by projecting the 3D object onto multiple planes (XY, YZ, ZX planes). Each plane undergoes independent 2D deformation processing, which is computationally simpler. The results are then synthesized to produce the final 3D deformation, effectively reducing processing complexity while maintaining deformation quality.
2Ease of operation
If skeleton model is used for three-dimensional object deformation, then deformation control is improved, but manual creation time and processing requirements increase
Solution Approach 1:
Instead of requiring manual creation of a skeleton model, the patent uses the object's existing geometric projection onto planes as a substitute. The projected 2D representations automatically capture the object's shape characteristics without requiring manual skeleton construction. This eliminates the time-consuming manual skeleton creation process while still enabling effective deformation control through the projected forms.
3Manufacturing precision
If physical simulation is executed for three-dimensional object deformation, then deformation accuracy is improved, but arithmetic processing amount increases
Solution Approach 1:
The patent reduces the computational burden by transforming the 3D physical simulation problem into 2D plane deformation problems. By projecting the object onto multiple planes and performing deformation operations in these 2D spaces, the arithmetic processing requirements are significantly reduced compared to executing full 3D physical simulations, while still achieving accurate deformation results through the synthesis of planar deformations.
