def setup():
    py5.translate(py5.width/4, py5.height/4)
    py5.shear_x(py5.PI/4.0)
    py5.rect(0, 0, 30, 30)

Description

Shears a shape around the x-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() function. Objects are always sheared around their relative position to the origin and positive numbers shear objects in a clockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling shear_x(PI/2) and then shear_x(PI/2) is the same as shear_x(PI). If shear_x() is called within the draw(), the transformation is reset when the loop begins again.

Technically, shear_x() multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by the push_matrix() and pop_matrix() functions.

Underlying Java method: shearX

Syntax

shear_x(angle: float, /) -> None
