Engineering Contradiction Analysis
1Manufacturing precision
If rigorous mathematical simulation is used to model object deformations, then realism and accuracy of deformation are improved, but processing overhead and computational complexity increase significantly
Solution Approach 1:
The patent segments the complex deformation modeling process into distinct components: collision detection, primitive deformation selection, and parameter interpolation. By dividing the problem into manageable segments, the system achieves accurate deformation results without requiring full rigorous mathematical simulation, thus reducing computational complexity while maintaining manufacturing precision.
Solution Approach 2:
The system changes parameters by using pre-defined primitive deformations with adjustable parameters instead of solving complex differential equations. Artists can control deformation by adjusting simple parameters like intensity and timing rather than dealing with complex mathematical models, maintaining accuracy while reducing the computational burden.
2Manufacturing precision
If rigorous mathematical simulation is used to model object deformations, then realism and accuracy of deformation are improved, but time required for calculation increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing primitive deformations in a library before they are needed. When deformation is required, the system retrieves pre-computed primitives and combines them through simple parameter interpolation rather than performing complex calculations in real-time, thus maintaining accuracy while significantly reducing calculation time.
Solution Approach 2:
The system uses copying by retrieving pre-computed deformation primitives from a library and replicating them with modified parameters. Instead of recalculating complex deformations each time, the system copies proven deformation patterns and adjusts them to fit specific scenarios, maintaining realism while reducing computational time.
3Manufacturing precision
If rigorous mathematical simulation is used to model object deformations, then deformation accuracy is improved, but ease of operation for artists deteriorates
Solution Approach 1:
The patent introduces an intermediary layer between the artist and the complex mathematical simulation. The system provides a user-friendly interface with pre-defined primitive deformations that artists can select and adjust through simple parameters. This intermediary abstraction shields artists from mathematical complexity while maintaining access to accurate deformation results through the underlying rigorous simulation engine.
Solution Approach 2:
The system enables artists to work with copied, simplified representations of complex deformations. By providing a library of pre-computed primitive deformations that can be copied and adjusted with simple parameters, the system makes deformation modeling accessible to artists without requiring them to understand or manipulate complex mathematical models, thus improving ease of operation while maintaining accuracy.
4Productivity
If conventional deformation modeling approaches are used, then processing overhead is reduced, but artistic control and realism are compromised
Solution Approach 1:
The system maintains processing efficiency by using parameter-based control of pre-defined primitive deformations rather than full mathematical simulation. Artists can achieve realistic results by adjusting parameters like intensity, timing, and combination of primitives, which provides both artistic control and realism while keeping processing overhead low compared to rigorous simulation of all deformation scenarios.
Solution Approach 2:
The patent applies composite materials by combining multiple simple primitive deformations to create complex realistic deformation effects. Instead of using a single complex simulation model, the system composes final deformations from multiple simpler primitives, each with low computational cost, achieving realistic composite effects while maintaining processing efficiency.

AI summary
There are provided systems and methods for performing object deformation modeling. One example system includes a hardware processor, a system memory, and a contact-based deformation modeling software stored in the system memory. The hardware processor is configured to execute the contact-based deformation modeling software to receive a first object geometric data corresponding to a first virtual object and a second object geometric data corresponding to at least a second virtual object, and to transform the first object geometric data by an n-dimensional mapping onto an object deformation space determined based on n primitive deformations. The hardware processor is also configured to execute the contact-based deformation modeling software to model a deformation of the first virtual object due to contact with at least the second virtual object, based on the n-dimensional mapping and a definition of direction for an object-to-object contact force.
