# 3D Shearing in Computer Graphics

--

We can denote shearing with **‘SHx,’ ‘SHy,’ and ‘SHz.’ **These ‘**SHx,’ ‘SHy,’ ‘SHz’ **are called** “Shearing factor.”**

The basic difference between 2D and 3D Shearing is that the 3D plane also includes the z-axis.

We can perform shearing on the object by following three ways-

**Shearing along the x-axis:**In this, wecan store the x coordinate and only change the y and z coordinate.

We can represent shearing along x-axis by the following equation-

**x1 = x0**

**y1 = y0 + SHy. x0**

**z1 = z0 + SHz. x0**

**2.** **Shearing along the y-axis: **In this, wecan store the y coordinate and only change the x and z coordinate.

We can represent shearing along with y-axis by the following equation-

**x1 = x0 + SHx. y0**

**y1 = y0**

**z1 = z0 + SHz. y0**

**3. Shearing along with z-axis: **In this, wecan store the z coordinate and only change the x and y coordinate.

We can represent shearing along with z-axis by the following equation-

**x1 = x0 + SHx. z0**

**y1 = y0 + SHy. Z0**

**z1 = z0**
