This node is used to evaluate an input geometry or matrix at a range of times defined by the "startTime", "endTime" and "increment" attribute values. When a geometry is attached as the input, the output is a sequence of time-evaluated geometries, which is referred to in maya as an "animated snapshot". When a matrix is attached as the input, the output is a an array of points that indicate the motion trail of the input matrix data.
