// Drawing vertices in 3D requires P3D
// as a parameter to size()

vertex(85, 20, -50);

example pic
size(100, 100, P3D);
PImage img = loadImage("laDefense.jpg");
noStroke();
beginShape();
texture(img);
// "laDefense.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. It is used exclusively within the beginShape() and endShape() functions.

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

This function is also used to map a texture onto 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)

x float: x-coordinate of the vertex
y float: y-coordinate of the vertex
z float: z-coordinate of the vertex
u float: horizontal coordinate for the texture mapping
v float: vertical coordinate for the texture mapping
