PROBLEM TO BE SOLVED: To provide an animation producing method which easily obtain three- dimensional data at many points on a model surface as to the respective modes of a model in operation. SOLUTION: In the animation producing method which obtains three- dimensional data on many points on the surface of the model 1 and performs hidden-line erasure, hidden-surface erasure, shade calculation, etc., by using those three-dimensional data to continuously display the operation of the model 1, a process wherein the three-dimensional data on the points on the surface of the model 1 are obtained by using an X-ray CT device consisting of a gantry 6 having an X-ray tube 8, an X-ray detector 9, etc., inside and an image reconstitution part 11 is repeated as to the respective modes of the model 1 in operation to obtain three-dimensional points at many points on the surface of the model 1 as to the respective formes of the model 1 and also obtain three- dimensional data on the formes in the operation of the model 1 between successive formes of the model by interpolation calculation. |
