Finally found another site that allows the sharing of deep zoom images. Basically they are just super high resolution images that exceed the maximum properties allowed by regular JPEG files, allowing gigapixel sized images that load detail based only upon the area you are viewing, rather than attempting to load the entire image into memory at one time.
This image is only a bit over 200 megapixels, and about 60 megabytes in size. I just used my phone, set at 2x, and took scanning shots of the front yard and assembled them with Microsoft ICE. With a better camera and better/longer lens, much higher quality/detail images should be easy to create. Just another nerdy photo thing to test, in case I ever need it for something…
Hmm… I think I’ve actually got two old HD Zoom gigapixel images of Lancaster from Mt Pleasant from several years ago (taken with the dSLR) that I should be able to convert and upload.
Four renders… quick, quick/good, slow/better, slow/best. It’s a bit difficult to see the differences between 1 and 2, and then 3 and 4, at this image size – but the larger the render, the more subtle details and changes you will notice. (Shadows, reflections, translucency, etc.) I’m going to work on a plug-in to see how close I can get it to photo-realistic.
