Definition |
This DRM class describes a cone or a pyramid shape of a light source or directional light in terms of direction vectors for the central axis (light direction) the vertical axis, and horizontal and vertical angular widths. |

Notes |
1 Horizontal_width defines the horizontal lobe width, (in radians) perpendicular to the VERTICAL_AXIS Reference Vector. 2 Vertical width defines the vertical lobe width, (in radians) parallel to the VERTICAL_AXIS Reference Vector. 3 One component defines the lobe axis direction with reference vector type = LIGHT_DIRECTION; the other component defines the vertical axis direction with reference vector type = VERTICAL_AXIS. |
