Multi-channel flame simulation method and apparatus
A method for simulating a candle flame with at least one computing device. The method may include controlling at least one lighting element according to at least a current wind value and a current flame value. The method may include controlling the current wind value and the current flame value by iteratively determining whether a first event occurred. When the first event is determined to have occurred, the method may include setting the current wind value to a random wind value and then changing the current wind value toward a baseline wind value. When the first event is determined to have not occurred, the method may include changing the current wind value toward the baseline wind value, determining whether a second event occurred. When the second event is determined to have occurred, the method may include setting the current flame value to a random flame value.
