Aspects of the present invention provide a system, method and computer program product for simulating movement of a projectile in a virtual environment. Primary data comprising a plurality of sets of position values and a plurality of time values for a projectile is received, with each time value in the primary data being associated with one of the sets of position values. The primary data is processed to generate secondary data that represents at least two consecutive sets of positions. Each set of positions includes a start position and an end position for the projectile, and the secondary data further represents a velocity of the projectile associated with each start position. The secondary data is used to simulate movement of the projectile in the virtual environment.
