Analysis: Mathematics: XYZ Surface Area
Calculate surface area of XYZ data
This feature is for OriginPro only, 8.1 SR0.
xyzarea iz:=col(c) area:=area;
Please refer to the page for additional option switches when accessing the x-function from script
This X-Function is used to calculate the area of the input XYZ surface. You can specify a variable for the result area. Also, the result area will be always put to the Results Log Window automatically.
This example is going to calculate the area of the input XYZ data range.
In three dimensions Cartesian space, the area of a general triangle is
To calculate the area of XYZ data, triangulation performance (like picture shown below) is going first, then the area of XYZ data is the sum of the area of every resulting triangle.
