Name | ### 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();
    PImage a = loadImage("arch.jpg");
    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
y | int or float: y-coordinate of the vertex
z | int or float: z-coordinate of the vertex
u | int or float: horizontal coordinate for the texture mapping
v | int or float: vertical coordinate for the texture mapping
Returns | None
Usage | Application & Web
