Paper Abstract

The Quick Image Display (QUID) model accurately computes and displays radiance images at animation rates while the target undergoes unrestricted flight or motion. Animation rates are obtained without sacrificing radiometric accuracy by using three important innovations. First, QUID has been implemented using the OpenGL graphics library which utilizes available graphics hardware to perform the computationally intensive hidden surface calculations. Second, the thermal emission and reflectance calculations are factorized into angular and wavelength dependent terms for computational efficiency. Third, QUID uses OpenGL supported texture mapping to simulate pseudo curved surface reflectance. The size of the glint texture is controlled by paint/surface properties and the surface normals at the facet's vertices. QUID generates IR radiance maps, in-band and spectral signatures for high level of detail targets with thousands of facets. Model features are illustrated with radiance and radiance contrast images of aircraft.
