Py5Shape.set_texture_uv()

Set the uv texture mapping coordinates for a given vertex in a Py5Shape object.

Examples

def setup():
    py5.size(100, 100, py5.P2D)
    img = py5.load_image("tower.jpg")
    s = py5.create_shape()
    s.begin_shape()
    s.vertex(20, 20)
    s.vertex(20, 80)
    s.vertex(80, 80)
    s.vertex(80, 20)
    s.end_shape(py5.CLOSE)

    s.set_texture(img)
    s.set_texture_mode(py5.NORMAL)
    s.set_texture_uv(0, 0, 0)
    s.set_texture_uv(1, 0, 1)
    s.set_texture_uv(2, 1, 1)
    s.set_texture_uv(3, 1, 0)

    py5.shape(s)

Description

Set the uv texture mapping coordinates for a given vertex in a Py5Shape object. This method can only be used outside the Py5Shape.begin_shape() and Py5Shape.end_shape() methods.

The u and v coordinates define the mapping of a Py5Shape object’s 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.set_texture_mode() method.

Underlying Processing method: PShape.setTextureUV

Signatures

set_texture_uv(
    index: int,  # vertex index
    u: float,  # horizontal coordinate for the texture mapping
    v: float,  # vertical coordinate for the texture mapping
    /,
) -> None
