FOSP: Feature Orientated Sand Painting Generation

ABSTRACT

Sand painting is a visually distinctive art form characterized by granular textures and diverse expressive techniques, where sand grains are manipulated through various hand movements such as waving, seeping, sweeping, and stroking. However, traditional stylized methods often fail to capture the fine textures and diverse techniques unique to sand painting. In this paper, we propose a Feature‐Oriented Sand Painting (FOSP) inspired by real sand painting techniques, aiming to produce sand paintings with authentic sandy textures and diverse techniques. Our FOSP comprises three main modules: overall sand waving generation, extraction and drawing of sand reduction regions, and simulation of sand grain accumulation with multiple techniques. The first module generates fine sand‐grain textures, whereas the latter two focus on contour rendering to enrich detail expression. Experiments validate that our FOSP can generate high‐quality sand paintings rapidly, outperforming existing methods in sand painting generation tasks.
