The "Environment Editor" is used to edit the global attributes of the environment in Ez3d. This environment will affect all other lighting elements. Stunning effects of fog, haze, pollution, and smoke may be simulated using the following options in the interface.
Environment Type
Five different environment types are possible - "fog", "haze", "smoke", "mist" or "none".
Fog
This simulates an effect of fog. Opacity of the environment increases exponentially with distance from the eye when this option is used.
Haze
This simulates an effect of haze. Opacity of the environment increases linearly with distance from the eye when this option is used. It will be obvious from the display that "haze" is less drastic than "fog".
Smoke
This sets the environment type to smoke and simulates an effect of smoke. Opacity of the environment increases exponential squared with distance from the eye when this option is used.
Mist
This option only applies to the ray-traced image, and will not cause any change in the Ez3d scene. A global low-altitude mist effect of the specified color is produced in the rendered image with this option. The "Visibility" value affects the transmitivity value of the mist.
None
This option sets the default environment with no fog, haze, smoke or mist effects.
Visibility
This slider sets the visibility of the fog. In other words, how quickly the opacity of the fog increases with distance from the camera. A lower visibility value results in a thicker fog or haze.
Refraction Index
This slider is colored blue meaning that its effects will only show in the final rendered image. This sets the index of refraction of the specified medium -- fog, mist and so on. Index of refraction is a measure if how much a light ray deviates when passing through the medium. You may also use the text field to the right of the slider to enter a more precise value for index of refraction.
Environment Color
This color editor sets the color of the environment when the environment type is set to "Fog", "Haze", "Smoke" or "Mist". You can use either the color wheel or the RGB-value color sliders to set the value of the background color. See section on "Attribute - Color" for more information on using the color editor.
