How does the contour tool (3D Anaylst) work in detail?

Hello,

 

can anybody give me additional information on how contouring (3D Analyst) in ArcGIS works?

 

Looking at the explanations within the help files I got no satisfying answer. I derived a contour from a raster with a resolution of 1 m and a base contour located at 0.05 m above mean sea level.

 

Is it a TIN-interpolation based on the cell center points? I wonder why the distances between the vertices (contour) are so irregular...

 

Any information on how the contour-tool works in detail would be great!

 

Best regards

Thorsten Dey

 

this is how it looks like...
