Abstract
A hybrid object to image mapping system and method includes a fragment generator that can be employed in conjunction with an interpolator within an image accelerator. The fragment generator includes a forward mapping mechanism for forward mapping an object data array from object space to image space so as to generate an object address set including image space addresses for each of the object data points, a pixel traversal mechanism for receiving and traversing the object address set to determine what pixels in the image space are located within an area of the object data set, and a reverse mapping mechanism for receiving pixel address data and determining at least two distances for each of the pixels within the area and for reverse mapping each of the distances from the image space to the object space relative to said data values in the local data buffer. In architecture, the forward mapping mechanism, the pixel traversing mechanism, and the reversed mapping mechanism are preferably pipelined in the foregoing sequential order. Thus, the data values from the object data array and the transformed distance values can be for further processing by a scaling operation such as interpolation or minification with a minimum amount of hardware and without reducing image quality.
