Dear all,
I'm a beginner, I use the 3d slicer to create landmarks and generate
pseudolandmarks on the model surface of "wangyunzhi". Finally, I use the
projectsemilm(also function 3d slicer) to project the pseudolandmarks to
the model surface of "lizixuan". Now I try to use the slider3d function and
the relaxLM function of the morpho package to realize the sliding of the
pseudolandmarks. Code used is shown below:
##slider3d:
test <- bindArr(wangyunzhi, lizixuan, along=3)
dimnames(test)[[3]] <- c("wangyunzhi", "lizixuan")
fix <- c(1:26)
surp <- c(1:nrow(wangyunzhi))[-fix]
slide <- slider3d(test, SMvector=fix, deselect=TRUE, surp=surp,
sur.path=".",sur.type = "ply",mc.cores=1)
##relaxLM：
relax <- relaxLM(wangyunzhi,lizixuan, mesh=wangyunzhi.mesh,
SMvector=fix, deselect=TRUE, surp=surp)
The code worked well and pseudolandmarks were slid. My questions are as
follows:
1. I thought I slide the pseudolandmark of lizixuan. But it's actually
wangyunzhi. Did I do something wrong? If it's correct, should I continue to
slide other pseudolandmarks using the slid wangyunzhi as a reference?
2. The pseudolandmarks obtained by the two functions are different. I
read the manual that the two functions are different, I don't understand
what's different except the form of the returned result is different.
Can anyone help me?
Best wishes,
Ying
