Oberflächenklassifikation

Could you please provide the full title? The truncated "Oberflächenkla..." could refer to several topics. For example:

1) Oberflächenklasse — a term used in mathematics, geometry, or computer graphics describing a classification of surfaces and their properties, with relevance to surface representation and rendering.

2) Oberflächenkalkulation — used in manufacturing or coating industries to estimate quantities and costs related to processing a surface, including area measurements, material usage, and labor.

If you specify which topic you want (or provide the exact full title), I will generate a concise, neutral wiki-style article under 300 words.
