version Morpho (2.0.1) on CRAN; Rvcg (0.7.1) now on CRAN

I released a new version of Morpho (2.0.1) on CRAN. The most important change is that you won't need to install the additional command line tools anymore (with significant speed gains).
Other changes are:
- 'createAtlas' has new option "keep.fix" to specifiy landmarks that should be kept from sliding in case corrCurves are defined.
- wrote C++ implementation of 'covPCA' (much faster) to calculate PC-scores from distances between covariance matrices and added bootstrapping option to compute confidence intervals for PC-scores (removed obsolete options "mc.cores" and "scores")
- all functions calling trimesh-tools are now wrappers for much faster implementations from Rvcg
- placePatch now runs in parallel
- warpmovie3d now allows make movie of deformed mesh AND landmark
My new package Rvcg (version 0.7.1) is now on CRAN and takes care of most of the meshing stuff involved (it is quite fast and based on the C++ routines from MeshLab - http://vcg.sf.net/). Currently, it is sporting the following functions:
|
vcgBary |
get barycenters of all faces of a triangular mesh |
|
vcgBorder |
find all border vertices and faces of a triangular mesh |
|
vcgClean |
Clean triangular surface meshes |
|
vcgClost |
Project coordinates onto a target triangular surface mesh. |
|
vcgClostKD |
Project coordinates onto a target triangular surface mesh using KD-tree search |
|
vcgCurve |
calculate curvature of a triangular mesh |
|
vcgGetEdge |
Get all edges of a triangular mesh |
|
vcgImport |
Import common mesh file formats (e.g. OBJ, STL, PLY) |
|
vcgIsolated |
Remove isolated pieces from a surface mesh. |
|
vcgKDtree |
perform kdtree search for 3D-coordinates. |
|
vcgMeshres |
calculates the average edge length of a triangular mesh |
|
vcgNonBorderEdge |
Get all non-border edges |
|
vcgPlyRead |
Import ascii or binary PLY files. |
|
vcgPlyWrite |
Export meshes to PLY-files |
|
vcgQEdecim |
Performs Quadric Edge Decimation on triangular meshes. |
|
vcgRaySearch |
check if a mesh is intersected by a set of rays |
|
vcgSample |
Subsample points on a mesh surface |
|
vcgSmooth |
Smooth a triangular mesh |
|
vcgUpdateNormals |
update vertex normals of a triangular meshes or point clouds |
|
vcgVFadj |
find all faces belonging to each vertex in a mesh |
And, as always, you can track the ongoing development on github (https://github.com/zarquon42b) or sourceforge (https://sourceforge.net/projects/morpho-rpackage/)
and install it with the R-package "devtools" by issueing the command install_github("zarquon42b/Morpho") or install_github("zarquon42b/Rvcg") resepctively.
All the best
Stefan
