-torque-frame-count Number of animation steps/frames used in the animation. If the data contains a fewer number of total frames, the lesser value will be used.

-torque-resolution Spatial resolution in pixels. A resolution of 1 means no spatial aggregation of the data. Any other resolution of N results in spatial aggregation into cells of NxN pixels. The value N must be power of 2.

-torque-animation-duration Animation duration in seconds.

-torque-aggregation-function A function used to calculate a value from the aggregate data for each cell. See -torque-resolution.

-torque-time-attribute The table column that contains the time information used create the animation.
