Py5Shape.get_texture_u()

Py5Shape.get_texture_u()#

Get the horizontal texture mapping coordinate for a particular vertex.

Examples#

example picture for get_texture_u()

def setup():
    py5.size(100, 100, py5.P2D)
    img = py5.load_image("tower.jpg")
    s = py5.create_shape()
    s.begin_shape()
    s.texture(img)
    s.vertex(20, 20, 0, 0)
    s.vertex(20, 80, 0, 100)
    s.vertex(80, 80, 100, 100)
    s.vertex(80, 20, 100, 0)
    s.end_shape(py5.CLOSE)

    py5.shape(s)

    for i in range(s.get_vertex_count()):
        u = s.get_texture_u(i)
        v = s.get_texture_v(i)
        py5.println(f"vertex {i}: u = {u} v = {v}")

Description#

Get the horizontal texture mapping coordinate for a particular vertex. Returned values will always range from 0 to 1, regardless of what the Sketch’s texture_mode() setting is.

Underlying Processing method: PShape.getTextureU

Signatures#

get_texture_u(
    index: int,  # vertex index
    /,
) -> float
