Coding apparatus and method for orientation interpolator node |
摘要 |
<p>An encoding apparatus and method for an orientation interpolator node are provided. The encoding apparatus for an orientation interpolator node, which provides information on the rotation of an object in a 3-dimensional space, includes a field data input unit for extracting field data to be encoded at present from a key which indicates information on a position on a time axis where a change of a rotational movement on a time axis occurs and key values which indicate rotation information corresponding to the position information, by parsing the orientation interpolator node; an adaptive differential pulse code modulation (ADPCM) processing unit for converting the key value data into a quaternion, and then ADPCM processing the quaternion using a rotation differential converting matrix, and differential pulse code modulation (DPCM) processing the key data ; and a quantizing unit for quantizing the key data and key value data and outputting the quantized data.</p> |
