Walking along the shore, you come upon a gap in the trees. Moonlight is reflecting in the gentle waves. Do you notice? Or do you just continue walking? DESCRIPTION OF HOW THIS IMAGE WAS CREATED: Not many objects in this scene, rather, it is an exercise in texturing and lighting. All modelling was done directly in POV-Ray. The moon is the most detailed object. It is a large sphere with 400 random spheres subtracted from the surface, forming craters. The texture is a texture_map with two parts: smooth, dull "maria", and bright, jagged "mountains". These are combined in a rough bozo pattern. The water texture is a normal_map combining bumps and marble bump patterns, and is slightly reflective. The rocky land is a heightfield, with an earthlike brown texture. A halo object covers large areas of the sky, suggesting whispy clouds and nebulae. The stars are distant white spheres. The sky_sphere has a gradual fade from deep blue near the horizon, to black at the zenith. Also, it has a small, dark gradient right at ground level, to eliminate a sharp line at the horizon of the water. Four types of light sources with subtle light colors are very important to this scene: - Sunlight on the moon is extremely bright yellowish white. The sun itself is below the horizon, illuminating only the moon. - Earthshine on the rest of the moon is very dim blue/green - Moonshine onto the scene is dim yellowish white - Lit windows are dull yellow light sources
