data type.
Try it
This transformation is a shear mapping (transvection) that distorts each point within an element by a certain angle in the vertical direction. The ordinate coordinate of each point is modified by a value proportionate to the specified angle and the distance to the origin; thus, the farther from the origin a point is, the greater will be the value added it.
