Engineering Contradiction Analysis
1Manufacturing precision
If conventional two-dimensional stamps of fixed shape and size are used for paint simulation, then the implementation is simple, but the realism and accuracy of paintbrush deformation are poor
Solution Approach 1:
The patent applies dynamics by transitioning from static two-dimensional stamps to dynamic three-dimensional paintbrush models that deform in real-time based on user input. The system calculates brush deformation continuously as the brush moves across the canvas, allowing the brush shape and size to change dynamically according to pressure, velocity, and position, thereby achieving realistic paintbrush behavior while maintaining computational efficiency through optimized deformation algorithms.
2Manufacturing precision
If conventional techniques assume paintbrush does not pick up paint from canvas, then the simulation is computationally simpler, but the realism of paint interaction is poor
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing deformation characteristics in a deformation table before the actual painting operation. The system pre-processes brush deformation data based on various pressures, velocities, and positions, then retrieves and applies these pre-computed deformations during painting, avoiding repeated complex calculations and improving real-time performance while maintaining high accuracy in paint interaction simulation.
3Manufacturing precision
If conventional techniques stamp over existing paint without pickup, then the implementation is simpler, but the sampling artifacts and tessellation issues increase
Solution Approach 1:
The patent introduces an intermediary deformation table that acts as a mediator between the three-dimensional brush model and the two-dimensional canvas. This deformation table stores pre-computed brush deformation characteristics and serves as an intermediate data structure that facilitates accurate paint deposition without requiring complex real-time calculations, thereby reducing sampling artifacts and tessellation issues while improving paint deposition accuracy.
4Manufacturing precision
If three-dimensional brush models with paint pickup are implemented, then the realism of painting simulation is improved, but the computational complexity and processing time increase
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing deformation characteristics in a deformation table before the actual painting operation. The system pre-processes brush deformation data based on various pressures, velocities, and positions, then retrieves and applies these pre-computed deformations during painting, avoiding repeated complex calculations and improving real-time performance while maintaining high accuracy in paint interaction simulation.
Solution Approach 2:
The patent applies copying by creating a two-dimensional representation (deformation table) from the three-dimensional brush model. Instead of performing complex 3D calculations in real-time, the system copies essential deformation characteristics into a 2D data structure that can be efficiently queried and applied during painting operations, significantly reducing computational time while preserving the realistic behavior of three-dimensional brush deformation.

AI summary
A paint simulation system described herein includes a brush component that outputs a three-dimensional computer-implemented model of an image editing tool. A paint component receives the three-dimensional computer-implemented model and generates a two-dimensional map corresponding to a footprint of the three-dimensional model with respect to a computer-implemented canvas, wherein resolution of the two-dimensional map is substantially similar to resolution of a paint map of the computer-implemented canvas.
