## Description
Add a new vertex to a shape. All shapes are constructed by connecting a series of vertices. The `vertex()` method is used to specify the vertex coordinates for points, lines, triangles, quads, and polygons. It is used exclusively within the [](sketch_begin_shape) and [](sketch_end_shape) functions.
Drawing a vertex in 3D using the `z` parameter requires the `P3D` renderer, as shown in the second example.
This method is also used to map a texture onto geometry. The [](sketch_texture) function declares the texture to apply to the geometry and the `u` and `v` coordinates define the mapping of this texture to the form. By default, the coordinates used for `u` and `v` are specified in relation to the image's size in pixels, but this relation can be changed with the Sketch's [](sketch_texture_mode) method.
Underlying Processing method: [vertex](https://processing.org/reference/vertex_.html)
