shear_y()¶
Shears a shape around the y-axis the amount specified by the angle parameter.
Examples¶
1 2 3 4 | def setup():
py5.translate(py5.width/4, py5.height/4)
py5.shear_y(py5.PI/4.0)
py5.rect(0, 0, 30, 30)
|
Description¶
Shears a shape around the y-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_y(PI/2) and then shear_y(PI/2) is the same as shear_y(PI). If shear_y() is called within the draw(), the transformation is reset when the loop begins again.
Technically, shear_y() 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: shearY
Syntax¶
shear_y(angle: float, /) -> None
Parameters¶
angle: float - angle of shear specified in radians
