Py5Shape.set_texture_uv()¶
Set the uv texture mapping coordinates for a given vertex in a Py5Shape object.
Examples¶
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | 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)

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