FAKING A HORIZON3D Animation with Blender

The World settings

The area allows the modification of global environmental values such as; World (it’s the sky) Ambient Occlusion Environmental Lighting Indirect lighting Gather Mist Stars

World

Horizon Color is the colour at the Horizon. Zenith Color is the colour at te top. Types of Sky Paper Sky If this option is added, the gradient keeps its

characteristics, but it is clipped in the image (it stays on a horizontal plane (parallel to x-y plane): what ever the angle of the camera may be, the horizon is always at the middle of the image).

Blend Sky The background color is blended from horizon to zenith. If only this button is pressed, the gradient runs from the bottom to the top of the rendered image regardless of the camera orientation.

Real Sky If this option is added, the gradient produced has two transitions, from nadir (same color as zenith) to horizon to zenith; the blending is also dependent on the camera orientation, which makes it more realistic. The horizon color is exactly at the horizon (on the x-y plane), and the zenith color is used for points vertically above and below the camera.

Ambient Occlusion

Ambient Occlusion is a sophisticated ray-tracing calculation which simulates soft global illumination shadows by faking darkness perceived in corners and at mesh intersections, creases, and cracks, where ambient light is occluded, or blocked.

Gather

The Gather panel contains settings for the ambient occlusion quality. Note that these settings also apply to Environment Lighting and Indirect Lighting.

Ambient occlusion has two main methods of calculation: Raytrace and Approximate.

Ray tracing, ambient occlusion, and indirect lighting are computer-intensive processes.

Environmental & Indirect Lighting Environmental Lighting is the

ambient lighting of the environment The use of Indirect lighting is where

the colour of one object radiates onto another.

Mist & Stars

Mist Add a mist to your scene to enhance the

feeling of depth. http://

Stars Randomly covers the background with

halo-like dots. http://
