Everest CG and Photo ComparisonsSee also the Animation page
The pictures here are similar to those in the K2 and Kangchenjunga sections. They are all rollovers which show the CG composite, and with the mouse over you get the original photo. The renderings were done with World Construction Set 6. The terrain is derived from 90 meter DEM's which have been overlaid with Landsat photos. These photos have an on the ground resolution of about 14 meters so foregrounds have been broken up a bit with WCS bumpmaps. The only way I could get these bumps to show through the overlay was to make a bumpy ecosystem and use the "tint foliage" option on the colour map. This is set to fade out with distance from the camera.
90 meter Dem's are notorious for having large holes in mountainous areas, which is a blow as these are the areas I am interested in. The holes can be patched with 900m DEM's but this results in a very inaccurate smoothing out of the terrain as you can see on the K2 stuff. (I will be updating this later) . The solution to this is to use Jonathan de Ferranti's DEM's. He has painstakingly patched the holes in all the worlds areas over 7000m and they look just like the real thing as you can see from the pictures below. The Everest region was so bad that I had not considered rendering it. Visit his site for a full account of his work and to download the data at www.viewfinderpanoramas.org If you want a look at the unpatched data have a look at Everest on Microsoft's Virtual Earth! |

This picture is the view from the lookout above Namche Bazar looking down the valley to Everest. Everest is the peak to the left of centre peeking over the ridge of Nuptse 7896m. To the right is Lhotse 8510m. |
| Here we have Ama Dablam 6856m seen from the trail heading to Phortse Tenga. Camera position here was uncertain. | ![]() |

This was taken from the summit of Gokyo Ri 5360m, looking down the Ngozumpa Glacier. The frozen Gokyo lake is in the foreground and the peak to the left of centre is Cholatse 6440m. |
| Everest is seen here, again, from Gokyo Ri. The Nuptse ridge is on the right and the snowy col on centre left is the Lho La on the border with Tibet. The north ridge, where Mallory and Irvine dissapeared, can be seen leading down to the left of the summit of Everest.
