1. Abstract

This paper presents a new framework for the semi-automatic synthesis of an inhomogeneous texture from a theoretically infinite number of input exemplars. Our algorithm generates a result with natural multiway transitions, maintaining a reasonable synthesis time to keep interactivity. We introduce intermediate textures between multiple exemplars, called ‘transition textures’ which enables our algorithm to produce smooth transitions between input exemplar patches. We also propose ‘image index correction’ to achieve a synthesis speed that is independent of the number of input exemplars by smart placement of transition-texture samples. Our algorithm is semiautomatic, spatially deterministic and well suited to acceleration via parallel processors. Also, our algorithm can easily control the synthesis result to design a texture visual with user interactions.

Result 1 : Air bubble shapes like needles.
The bubbles formed will align to a direction similar to the direction of the ice growth

Result 2 : Progressive Result: (Top left) Without any opaque area (Top right) Using particle only (Bottom left) Dissolved air field only (Bottom right) Both particles and the field
