Paper Abstract

Aliasing is unavoidable in real-time computer image generation due to the sampling processes occurring within the graphics hardware. In particular, aliasing produces scintillation effects and significant radiometric inaccuracy when targets are rendered at long range. This problem was alleviated some years ago by the development of a zoom anti-aliasing (ZAA) technique within infrared missile seeker hardware-in-the-loop simulations. An alternative ZAA technique based on extensive use of available graphics hardware functions is described here and compared to the original technique.
