| Description: | A port of the C++ routine for applying the marching cubes algorithm written by Thomas Lewiner et al. (2012) <doi:10.1080/10867651.2003.10487582> into an R package. The package supplies the contour3d() function, which takes a 3-dimensional array of voxel data and calculates the vertices, vertex normals, and faces for a 3d mesh representing the contour(s) at a given level. |

Compute Isosurface, a Three Dimension Contour
Description
Computes a 3D contours or isosurface by the marching cubes algorithm.
Usage
contour3d(griddata, level, x, y, z)
Arguments
griddata |
A three dimensional array from which to calculate the contour |
level |
The level at which to construct the contour surface |
x, y, z |
locations of grid planes at which values in |
Value
Returns a list with coordinates of each surface vertex, indices of the vertices that make up each triangle, and surface normals at each vertex
