====== More screenshots ====== Due to popular demand, I've taken a few more screenshots of the cliffs from [[l3dt:2006:may:23|a few days ago]] with the lighting adjusted to remove shadows:
| {{:l3dt:2006:may:16xtex1.jpg?350}} | {{:l3dt:2006:may:16xtex4.jpg?350}} | ^ Image from the 23rd of May ^ Sun at high-noon ^ | {{:l3dt:2006:may:16xtex3.jpg?350}} | {{:l3dt:2006:may:lowrestx.jpg?350}} | ^ Sun facing cliffs, 30° elevation ^ 1x texture res ^
As you can see, the bump-mapping effect is diminished when the lighting is face-on to the surfaces. Sadly, this is how //[[wp>Lambertian_reflectance|Lambertian reflectance]]// is supposed to work, so it's not something I can really 'fix'. Oh, by the way, the map itself was a little 256x256 heightfield with an 4096x4096 mosaic texture. Both the light-map and texture-map were 16x high-res, with bump-mapping and per-pixel land types enabled. The texture calculation took about 6 minutes on my 2Ghz AMD (it's ~2.5 minutes with 'per pixel land types' disabled). Cheerio, Aaron. ----- //Edit: // Oops, I forgot to mention that when rendering the above scenes, L3DTVi2 was pushing 144 frames per second on an ancient nVidia FX5700 card. {{tag>bump_maps L3DTVi2}}
