Name | ### shearX()
Examples |
    size(100, 100, P2D);
    translate(width/4, height/4);
    shearX(PI/4.0);
    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 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 shearX(PI/2) and then shearX(PI/2) is the same as shearX(PI). If shearX() is called within the draw(), the transformation is reset when the loop begins again. This function works in P2D or JAVA2D mode as shown in the example above. Technically, shearX() multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by the pushMatrix() and popMatrix() functions.
Syntax |
    shearX(angle);
