When creating a surface, into which simple geometric shape does the software group the points?

Explanation:
When building a surface from points, the software uses the simplest, most reliable building block: triangles. A triangle is the smallest polygon, and three points always determine a single plane, so the facet is guaranteed to be flat. This makes modeling and rendering robust, because any complex surface can be approximated by many tiny triangles forming a triangular mesh. Other shapes like circles or rectangles aren’t used as the fundamental surface units; if you tried to use them directly, noncoplanar points could create non-flat facets. In practice, even rectangular patches are usually split into triangles under the hood for processing, so the result is a mesh of triangles that accurately represents the surface.
