Name
shearY()
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 PI*2) 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
shearY(PI/2) and then shearY(PI/2) is the same as
shearY(PI). If shearY() is called within the
draw(), the transformation is reset when the loop begins again.
Technically, shearY() multiplies the current transformation
matrix by a rotation matrix. This function can be further controlled by
the pushMatrix() and popMatrix() functions.
Examples
size(400, 400); translate(width/4, height/4); shearY(PI/4.0); rect(0, 0, 120, 120);
Syntax
shearY(angle)
Parameters
angle
(float)
angle of shear specified in radians
Return
void
