### vertex()

Examples
```beginShape(POINTS);

vertex(30, 20);

vertex(85, 20);

vertex(85, 75);

vertex(30, 75);

endShape();```
```// Drawing vertices in 3D requires P3D

// or OPENGL as a parameter to size()

size(100, 100, P3D);

beginShape(POINTS);

vertex(30, 20, -50);

vertex(85, 20, -50);

vertex(85, 75, -50);

vertex(30, 75, -50);

endShape();```
```noStroke();

beginShape();

texture(a);

// "arch.jpg" is 100x100 pixels in size so

// the values 0 and 100 are used for the

// parameters "u" and "v" to map it directly

// to the vertex points

vertex(10, 20, 0, 0);

vertex(80, 5, 100, 0);

vertex(95, 90, 100, 100);

vertex(40, 95, 0, 100);

endShape();```
Description All shapes are constructed by connecting a series of vertices. vertex() is used to specify the vertex coordinates for points, lines, triangles, quads, and polygons and is used exclusively within the beginShape() and endShape() function.

Drawing a vertex in 3D using the z parameter requires the P3D or OPENGL parameter in combination with size as shown in the above example.

This function is also used to map a texture onto the geometry. The texture() function declares the texture to apply to the geometry and the u and v coordinates set 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 textureMode().
Syntax
```vertex(x, y);

vertex(x, y, z);

vertex(x, y, u, v);

vertex(x, y, z, u, v);```
Parameters
x int or float: x-coordinate of the vertex int or float: y-coordinate of the vertex int or float: z-coordinate of the vertex int or float: horizontal coordinate for the texture mapping int or float: vertical coordinate for the texture mapping
