getTArea: Compute triangle area from 3D coordinates
In cornelmpop/Lithics3D: A toolbox for 3D analysis of archaeological lithics
getTArea R Documentation
Compute triangle area from 3D coordinates
Description
Computes the area of a triangle from 3D coordinates
Usage
getTArea(coords)
Arguments
coords
a vector of concatenated xyz coordinates. Note that only the
first 9 values will be used.
Value
numeric value of the computed area (0 for degenerate triangles) or
NA in case of bad input
Note
this function is currently too slow - 100k calls are processed in ~3.4
seconds.
Examples
# input format: c(x,y,z,x1,y1,z1,x2,y2,z2)
triangle <- c(-2,0,5,-10,-2,-1,0,0,0)
