2个都不规则,画的是个示意图
左边的坐标已经有了,A-H包括下面几个未标注的顶点坐标都有;
右边只有a-h这8个坐标,用哪种变换可以求出未标注的顶点坐标
等于是2个图形要变换过去,这种问题有什么理论支撑吗? |

发帖数: 1154 | 3 the transformation is what I need to calculate. the only information i got
is all coordinates in the old model and some feature coordinates in the new
model.
i need to calculate all points in new model.
any clue?
thx

左边标准的,2个眼一个嘴
右边是变形的,2个眼坐标知道,想把嘴和其余部分点求出来

shape and the right diagram is the deformed shape under certain constraints.
Then you can run the simulation to get the deformed shape.
The result should be equivalent to variational approaches under certain
energy metrics. |
