scale a mesh of class "mesh3d"
scales (the vertices of a mesh by a scalar
scalemesh(mesh, size, center = c("bbox", "mean", "none"))mesh |
object of class "mesh3d" |
size |
numeric: scale factor |
center |
character: method to position center of mesh after scaling: values are "bbox", and "mean". See Details for more info. |
The mesh's center is determined either as mean of the bounding box (center="bbox") or mean of vertex coordinates (center="mean") and then scaled according to the scaling factor. If center="none", vertex coordinates will simply be multiplied by "size".
returns a scaled mesh
