Environmental Visualization System A product of the USDA Forest Service, Pacific Northwest Research Station News Flash EnVision is finally ready for release.
Applicable projects range from a few to several thousand acres.
The system is built upon many of the original concepts used to develop the Vantage Point visualization system. However, EnVision does not attempt to model changes to the landscape over time. EnVision models individual light sources including a simulated sun position and atmospheric effects such as fog and haze. EnVision renders images using a geometrically correct camera model making it possible to match real photographs taken from known viewpoints to simulated scenes. Early releases of Windows 95 may require addition of the OpenGL libraries before EnVision can operate.
