Pinnanmalli
Pinnanmalli, or surface model, is a mathematical or computational representation of the outer surface of a three-dimensional object. It describes the geometry of a surface and, depending on the context, may also encode texture, curvature, and other properties. The term is used across fields such as computer graphics, computer-aided design (CAD), geology, and geography, and is often translated as surface model or surface representation in English.
Surface models can be categorized by how they describe geometry. Parametric surfaces define points on the surface
Data for pinnanmalli can come from various sources, including CAD data, 3D scanning, photogrammetry, or algorithmic
Advantages and limitations vary by representation. Parametric and implicit models can offer smooth, precise surfaces and
