Solution Overview
Problem
Conventional digital art software struggles with simulating fluids like watercolors and wet oils due to limitations in modeling techniques, such as fixed-sized simulation areas and inefficient processing, which hinder realistic drawing and painting experiences.
Innovation Solution
The implementation of dynamically sized simulation areas and novel modeling techniques, such as 'wet rectangle,' 'wet spans,' and 'wet tiles,' which adjust simulation sizes based on fluid presence, and a multi-layer scheme for simulating fluid behavior, allowing for more efficient and realistic fluid simulations.

Engineering Contradiction Analysis
1Manufacturing precision
If fixed-sized simulation areas are used, then device complexity is reduced, but manufacturing precision deteriorates
Solution Approach 1:
The simulation area dynamically adjusts its size and shape based on the distribution of fluid particles. Instead of using a fixed simulation grid, the system identifies the bounding box of wet cells and expands or contracts the simulation area accordingly, allowing the simulation to adapt to the actual fluid extent and maintain accuracy while reducing unnecessary computations in dry areas.
2Productivity
If conventional Lattice Boltzmann Modeling is used, then ease of operation is maintained, but productivity deteriorates
Solution Approach 1:
The simulation domain is divided into wet cells and dry cells based on fluid presence. The system segments the computation by identifying only the relevant wet regions where fluid simulation is needed, excluding dry areas from computation. This segmentation significantly improves productivity by reducing the number of cells that require intensive LBM calculations while maintaining the ease of using the conventional LBM framework.
3Loss of time
If simulation area is not dynamically adjusted, then device complexity is reduced, but loss of time deteriorates
Solution Approach 1:
The simulation system automatically identifies wet cells and computes the bounding box of the fluid region without requiring external intervention or manual parameter setting. The simulation area dynamically adjusts itself based on the current fluid distribution, reducing computation time by focusing resources only on relevant regions while the system self-manages the complexity of area adjustment.
