Real-Time Auto Stylized Sand Art Drawing

We propose a new method for auto stylized sand art drawing. Our system is built on top of our sand drawing system which is mixed with a particle system and a height map. An image is input and the patterns of the image is analyzed. The contours of the image are computed and they are converted into strokes. In sand art drawing, artists can use multiple fingers to draw the strokes which are symmetric or parallel at the same time. Our system detects such strokes and groups them according to geometric rules. After analyzing the image and collecting a set of strokes, we enter the drawing stage. In the drawing stage, our system automatically performs sand spilling, drawing strokes, leaking, erosion, pinch spilling and pinch erosion.
