The WebRTIViewer is a HTML5-WebGL viewer for high resolution RTI images (PTM and HSH) and standard images (JPEG, PNG and TIF). It allows the visualization of your image in a standard web page without the installation of any plugin using a recent web-browser (Google Chrome from the version 9.0, Mozilla Firefox from the version 4.0, Internet Explorer from the version 11.0 and Safari from the version 6.0). The download link contains all the necessary tools for the preprocessing of the image to create a multi-resolution streamable format (the webGLRTIMaker tool) and for the visualization of the image in your HTML page (WebRTIViewer).
