Abstract

Examples of creating moving light patterns in a light pipe having a plurality of Light Emitting Diodes (LEDs) are described. In an example, a plurality of keyframes is obtained. The plurality of keyframes define the moving light pattern. Each keyframe is indicative of red-greenblue (RGB) illumination values of each LEDfrom the plurality of LEDs. Further, a linear interpolation is performed, at run-time, between two keyframes of the plurality of keyframes to obtain a plurality of interpolated frames. Each interpolated frame is indicative of interpolated RGB illumination values of each LED. Based on the RGB illumination values of 10 the plurality of keyframes and interpolated RGB illumination values of the plurality of interpolated frames, the plurality of LEDs is illuminated, to create the moving light pattern.
