# SCNPyramid

A right rectangular pyramid geometry.

## Declaration

```swift
class SCNPyramid
```

## Overview

Overview

A pyramid defines the surface of a solid whose base is a rectangle, and whose four triangular side faces converge at a point centered above its base. Define the shape of the pyramid’s base in the x- and z-axis dimensions of its local coordinate space with the width and length properties, and its extent in the y-axis dimension with the height property. To position and orient a pyramid in a scene, attach it to the geometry property of an SCNNode object. Control the level of detail with the widthSegmentCount, lengthSegmentCount, and heightSegmentCount properties. A higher segment count produces more vertices, which can improve rendering quality for certain lighting models or custom shader effects, but at a cost to rendering performance. A pyramid contains five SCNGeometryElement objects, corresponding to its base and each of its four sides. SceneKit can render each element using a different material. For details, see the materials property in SCNGeometry.
