# SCNGeometryPrimitiveType

The drawing primitive that connects vertices when rendering a geometry element, used by the [`primitiveType`](/documentation/SceneKit/SCNGeometryElement/primitiveType) property to specify how SceneKit interprets the geometry element’s data.

```
enum SCNGeometryPrimitiveType
```

## Topics

### Constants

[`SCNGeometryPrimitiveTypeTriangles`](/documentation/SceneKit/SCNGeometryPrimitiveType/triangles)

The geometry element’s data is a sequence of triangles, with each triangle described by three new vertices.

[`SCNGeometryPrimitiveTypeTriangleStrip`](/documentation/SceneKit/SCNGeometryPrimitiveType/triangleStrip)

The geometry element’s data is a sequence of triangles, with each triangle described by one new vertex and two vertices from the previous triangle.

[`SCNGeometryPrimitiveTypeLine`](/documentation/SceneKit/SCNGeometryPrimitiveType/line)

The geometry element’s data is a sequence of line segments, with each line segment described by two new vertices.

[`SCNGeometryPrimitiveTypePoint`](/documentation/SceneKit/SCNGeometryPrimitiveType/point)

The geometry element’s data is a sequence of unconnected points.

### Enumeration Cases

[`SCNGeometryPrimitiveTypePolygon`](/documentation/SceneKit/SCNGeometryPrimitiveType/polygon)
