Solution Overview
Problem
Current technologies face challenges in simulating a realistic three-dimensional representation of padded garments, particularly in capturing the varying shapes and appearances due to different fillings, which is essential for design and visualization purposes.
Innovation Solution
A method involving the generation of two-dimensional patterns for a 3D padded garment, where an intermediate pattern is used to simulate internal pressure and collision effects, allowing for the transformation of these patterns in 3D space based on physical properties and filling information, and the display of the resulting 3D garment with realistic deformation and wrinkle effects.

1Productivity
If a simple 2D pattern representation is used for padded garments, then the design process is simplified and faster, but the realistic representation and visual accuracy of the padded garment appearance is lost
Solution Approach 1:
The patent transforms 2D garment patterns into 3D virtual representations by adding a depth dimension that accounts for padding thickness. The system calculates 3D coordinates by offsetting surface points along normal vectors by distances corresponding to padding thickness, enabling realistic visualization while maintaining computational efficiency of 2D pattern processing.
Solution Approach 2:
The patent introduces an intermediate virtual surface layer between the inner and outer garment surfaces to represent the padding material. This intermediate layer acts as a mediator that carries padding thickness information and enables the generation of realistic outer surface geometry without requiring complex direct modeling of the padding material itself.
2Measurement precision
If complex 3D modeling techniques are used to achieve realistic padded garment representation, then visual accuracy is improved, but computational complexity and processing time increase
Solution Approach 1:
The patent creates a virtual copy of the garment surface at a calculated offset distance to represent the outer surface with padding. Instead of modeling the actual padding material with complex physics, the system generates a simplified geometric copy that preserves the essential visual characteristics through mathematical offsetting operations.
Solution Approach 2:
The patent modifies geometric parameters by applying offset distances along surface normal vectors to transform inner surface coordinates into outer surface coordinates. This parameter-based approach allows realistic 3D representation through simple coordinate transformations rather than complex material modeling.
3Measurement precision
If padding thickness varies throughout the garment to achieve realistic appearance, then visual accuracy is improved, but the complexity of defining and managing varying thickness parameters increases
Solution Approach 1:
The patent applies different padding thickness values at different locations on the garment surface by associating specific offset distances with particular surface regions or pattern elements. This allows realistic variation in padding appearance while managing complexity through localized parameter assignment rather than global uniformity.

AI summary
According to an embodiment, a method of simulating a three-dimensional (3D) padded garment includes generating a second pattern corresponding to a first pattern that is a two-dimensional (2D) pattern, generating an intermediate pattern positioned between the first pattern and the second pattern to which a pressure value is applied, wherein the intermediate pattern comprises a collision value, and generating the 3D padded garment based on at least one of the first pattern, the second pattern, and the intermediate pattern.
