1. A hybrid object to image mapping method for mapping image data on a computer-based system, comprising the steps of:

  • receiving an object data array comprising a plurality of object data points in object space, each said point having an associated data value;

    placing said data values in a local data buffer,forward mapping said object data array from object space to image space so as to generate an object address set comprising image space addresses for each said object data point;

    traversing said object address set to determine which pixels in said image space that are located within an area of said object data set;

    determining at least one X and Y distance for each said pixel within said area said pixel being within said image space, said X and Y distance representing said pixel'"'"'s distance from a reference point in said object data set; and

    reverse mapping each said distance from said image space to said object space relative to said data values in said local data buffer.
