It's a small-scale outdoor scene, with visibility limited to a couple dozen meters, rather than hundreds. The camera follows a small flickering firefly as it darts through the ferns and firs, while varying dynamic shadows are cast everywhere. The full moon shines a pale blue light over the scene, and all those leaves sway a little in the breeze. The vegetation on the ground is dynamically distributed where it's needed, according to the camera movements. Its level of detail is also dynamically altered depending on the distance to the camera. The other key interest in this scene is the lighting and dynamic shadow system. This scene is really ideal for showing the benefits of perspective shadow maps-- the new shadow mapping technique used in all three 3DMark05 game scenes. We'll have more on perspective shadow maps later. The ground material is like the metal material in Return to Proxycon, but with added diffuse, diffuse detail, normal, and normal detail maps. The rock surfaces also have a specular map. The tree branches are a modified metal material without a specular map and with a diffuse cube map and no bump mapping. The sky material does procedural light scattering. The moonlight is directional, generating dynamic shadows using a 2048x2048 resolution depth map. The illuminating firefly is a masked point light, throwing shadows using a 512x512x6 cube depth map.(Less)
