HD View supports smooth panning and zooming, as well as appropriate viewing perspectives as you zoom in and out. HD View also makes creating and hosting your own HD View images easy. HD View is available as a plug-in for Windows-based browsers. Recent advances in camera and sensor technology and software for stitching images together has led to the creation of images containing billions of pixels (gigapixels). These images are often panoramic, that is, they cover very wide fields of view. Since monitors typically contain only one to two million pixels, it is only possible to actually see 1/1000th of such image data at once. Also, viewing very wide fields of view require unwrapping of an image projected onto a curved surface (think of a map of the world) which can cause distortions"; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
