tangent mapping

In this paper, the consistent tangent modulus method is compared with the radial return mapping algorithm and it is found that the former is not more numerical efficient than the latter, not as some paper reported.

分析了弹塑性一致切线模量算法与径向返回算法，发现一致切线模量算法并不如有关文献报道的那样，比径向返回算法有快得多的收敛速度，两个算例表明了这一点。

Parallax mapping uses the concept of tangent space in the same manner.

视差贴图同样使用了这样的切线空间的概念.

The method of mapping through tangent vector is introduced to obtain ideal point location in physical space, which improves the mesh quality around the poles.
