# MTLPrimitiveType

The geometric primitive type for drawing commands.

```
enum MTLPrimitiveType
```

## Topics

### Geometric primitive types

[`MTLPrimitiveType.point`](/documentation/Metal/MTLPrimitiveType/point)

Rasterize a point at each vertex. The vertex shader needs to provide `[[point_size]]`, or the point size is undefined.

[`MTLPrimitiveType.line`](/documentation/Metal/MTLPrimitiveType/line)

Rasterize a line between each separate pair of vertices, resulting in a series of unconnected lines. If there are an odd number of vertices, the last vertex is ignored.

[`MTLPrimitiveType.lineStrip`](/documentation/Metal/MTLPrimitiveType/lineStrip)

Rasterize a line between each pair of adjacent vertices, resulting in a series of connected lines (also called a polyline).

[`MTLPrimitiveType.triangle`](/documentation/Metal/MTLPrimitiveType/triangle)

For every separate set of three vertices, rasterize a triangle. If the number of vertices is not a multiple of three, either one or two vertices is ignored.

[`MTLPrimitiveType.triangleStrip`](/documentation/Metal/MTLPrimitiveType/triangleStrip)

For every three adjacent vertices, rasterize a triangle.
