Abstract
A three-dimensional skeleton data error absorbing apparatus is provided, which is capable of rendering an object at a correct rendering position by absorbing an error based on skeleton data calculation. A fixed skeleton portion specifying part 20 specifies a fixed skeleton portion whose rendering position is desired to be fixed, and a skeleton matrix calculating part 40 obtains a coordinate of a fixed position. A skeleton length detecting part 31, a skeleton hierarchy level detecting part 32, and an error absorption priority detecting part 33 of an error absorbing skeleton specifying part 30 select an error absorbing skeleton that absorbs an error. An error absorption calculating part 60 obtains, by inverse matrix calculation, a determinant, which should be satisfied by a skeleton matrix of error absorbing skeleton, based on the matrix calculation results and the coordinate of a fixed position of the other skeletons. An error based on the difference in a platform is simulated in a resource environment of an assumed platform, and error absorption processing is conducted so as to absorb the error results.
