Arithmetic for nat dotprops and surface objects
     
    
    # S3 method for dotprops
Ops(e1, e2 = NULL)
# S3 method for mesh3d
Ops(e1, e2 = NULL)
# S3 method for hxsurf
Ops(e1, e2 = NULL)
 
     
    
    Arguments
    - e1
 
A dotprops or surface (hxsurf, mesh3d) object
 
- e2
 
A scalar or 3-vector that will be applied to the dotprops object
 
 
    
    Value
    A new dotprops / surface object
     
    
    
    Examples
    kcs20.shift=kcs20+c(2,3,4)
# \donttest{
plot3d(kcs20, col='grey')
plot3d(kcs20.shift, col='red')
# }
