| 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.
Technically, shearX() multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by the pushMatrix() and popMatrix() functions. |
