An augmented reality/mixed reality system that provides an immersive user experience. That experience is provided with increased speed of update with low computational resources for occlusion data representing a user's hand that can be used to occlude virtual objects. The hand occlusion data are generated by computing a hand mesh from live depth sensor data. A small amount of data is processed by masking live depth data with a model in which a hand is simply represented by multiple segments identified from key-points. The hand occlusion data may be generated by predicting changes in a hand pose between a time of capture of the depth data and the time when the hand mesh will be used for occlusion processing. The hand mesh may be distorted to represent the hand in the predicted pose.
