Title: Method for generating adaptively sampled distance field of object
Inventor: RONALD N PERRY
IPC: G06T17/00
Filed: 2002-03-14
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a ray casting method is unable to perform high-speed processing and a conventional ADF method is inferior in usability, requires a long time for conversion to a polygon, can correct only a distance value in a surface, and can be made fast by hardware. SOLUTION: This method determine a candidate cell of the adaptively sampled field to generate the adaptively sampled distance field of an object. Then the distance values of the candidate cell are determined and stored in a bounded distance tree. The candidate cell is recursively subdivided into subdivided cells of the adaptively sampled distance field until a termination condition is reached while the corresponding distance values of the subdivided cells are determined and stored in the bounded distance tree. Lastly, the distance values are added to corresponding cells to generate the adaptively sampled distance cell of the object.
