The mean value barycentric coordinates proposed by Floater will lead to singularity when a given point approaches the edge of polygon, causing numerical instability in geometric computation.

To promote the efficient reuse of existing animation resources,an approach for transferring 3D animation from a source mesh to a target mesh based on mean value coordinates is proposed.

The barycentric coordinates of the plane view projection of a coal face are solved with a formula of geometric gravity centre.

At first the original data points are resampled using barycentric coordinates,followed by fitting the resampled data points.

From some identities and the embedding inequality in the triangle,by using the substitution of the barycentric coordinates and method of completing the square,a ratio type inequality involving the distances from an arbitrary point to three vertexes and sides of the triangle is proved,some new results are obtained.

Then applying barycentric coordinate equation on the gotten GBD points,the mapping results were calculated.

During the point location, the barycentric coordinates are used to extract local heuristic information about the location of p so as.

By means of analyzing all directional derivatives of barycentric coordinate form of Be zier curves,an efficient evaluation method for this form has been furnished,and all the storage quantity and multiplication number are equivalent to that of de Castelisu algorithm.

The irrational function forms interpolation on a polygonal element with arbitrary nodal distribution was constructed by using mean value coordinates of polygonal elements.

In this paper,using mean value coordinates of polygon in computer graphics,the mean value interpolation method setting vertexes of polygon as interpolating nodes is presented.
