Sky Parameters

Sky_color

The color of the sky at the horizon. Overall sky color is linearly interpolated between Sky_color and Zenith_color.

Zenith_color

The color of the sky at the zenith (straight up). Overall sky color is linearly interpolated between Sky_color and Zenith_color.

Light_color

The color of the simulated fluorescent lights. These “lights” produce reflections in surfaces, but they do not actually illuminate surfaces.

Light Placement

The Light Placement parameters control the size and placement of the simulated fluorescent lights in the environment. These “lights” produce reflections in surfaces, but they do not actually illuminate surfaces.

Width, Depth

The width and depth of each light. These parameters also determine spacing between lights. The valid/slider range is 0 to 1. The default Width value is 0.5 and the default Depth value is 0.1.

Width_mult, Depth_mult

The number of lights per unit length. The valid/slider range is 0 to 1. The default value is 1.

Width_offset, Depth_offset

The light displacement. The slider range is 0 to 1. The default value is 0.

Floor Parameters

The Floor Parameters control the appearance of the environment’s floor.

Floor_color, Horizon_color, Grid_color

The color of the floor, the floor’s horizon and the floor’s grid.

Real_floor

If Real_floor is OFF, the environment’s floor is located at infinity, so reflections on moving objects or reflections viewed from a moving camera will be incorrect. The default setting is OFF.

If Real_floor is ON, the floor is located on the ground plane, so reflections on moving objects or reflections viewed from a moving camera will be correct. If Real_floor is ON, make sure surfaces or the camera do not go below the ground plane.

Grid Placement

The Grid Placement parameters control the size and placement of the floor’s grid.

Width, Depth

The width and depth of the grid lines. These parameters also determine the spacing between grid lines. The valid/slider range is 0 to 1. The default value is 0.1.

Width_mult, Depth_mult

The number of grid cells per unit length. The valid/slider range is 0 to 1. The default value is 1.

Width_offset,Depth_offset

The grid displacement. The slider range is 0 to 1. The default value is 0.
