| 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(). |
