CREATION Scene Generation for ATR Applications
Abstract
The CREATION (computer generation of realistic environments with atmospheres for thermal imagery with optics and noise) scene simulation program produces high-quality three-dimensional imagery of realistic bafflefield environments. Several important methodologies used in the CREATION program are discussed. These include efficient ground-texturing techniques that use growth-rule-based texture pallerns and gradient-of- steepest-descent algorithmic erosion processes to increase the realism of low-resolution Defense Mapping Agency (DMA) digital terrain elevation data (DTED). Methods discussed include algorithms to produce very realistic three dimensional trees that are succinctly described by a small number of geometrical parameters and efficiently rendered. Discussion of the vegetation model also includes a description of algorithms to efficiently render large masses of trees that smoothly and seamlessly increase in detail as the viewer continuously approaches them.
