This paper presents a synthesis model for generating infrared texture of aeolian sand ripples.  ...  Texture is of vital importance when rendering realistic infrared images. Traditional attempts to simulate infrared textures often suffer from insufficient realism seen in actual infrared images.  ...  Generally, infrared texture can be generated in two ways: conversion from images of the visible (VIS) band, and model-based IR texture synthesis.  ...
