Description

Add a new vertex to a Py5Shape object. 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 Py5Shape.begin_shape() and Py5Shape.end_shape() methods.

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 Py5Shape.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 Py5Shape object’s Py5Shape.texture_mode() method or by calling the Sketch’s texture_mode() method before the shape is created.

Underlying Java method: PShape.vertex

Syntax

vertex(x: float, y: float, /) -> None
vertex(x: float, y: float, u: float, v: float, /) -> None
vertex(x: float, y: float, z: float, /) -> None
vertex(x: float, y: float, z: float, u: float, v: float, /) -> None

Parameters

  • u: float - horizontal coordinate for the texture mapping

  • v: float - vertical coordinate for the texture mapping

  • x: float - x-coordinate of the vertex

  • y: float - y-coordinate of the vertex

  • z: float - z-coordinate of the vertex
