Clarifications |
1 This defines the horizontal lobe width, measured in degrees, between 0 and 360 inclusive. This is measured perpendicular to the VERTICAL_AXIS <DRM Reference Vector> component. 2 This defines the vertical lobe width, measured in degrees, between 0 and 360 inclusive. This is measured parallel to the VERTICAL_AXIS <DRM Reference Vector> component. 3 These are the lobe cross section axes. One component <DRM Reference Vector> specifies the lobe axis direction with vector_type = LIGHT_DIRECTION. The other component <DRM Reference Vector> specifies the vertical axis direction with vector_type = VERTICAL_AXIS. |
