Mapwing Viewer enables you to open and to explore Mapwing Project files (.flyp) and Mapwing Streaming files (.flys). Mapwing Viewer uses OpenGL to display tours smoothly and with high-quality graphics. Mapwing virtual reality tours are built from digital photos using Mapwing Creator Pro and can also be viewed using Macromedia Flash Player. Version 188.8.131.52 is a complete rewrite of Mapwing Viewer. It includes UTF-8 support for properly displaying foreign characters, better graphics performance, faster tour streaming, and adds online documentation.
