Abstract
Similar to transformations in 2D space discussed in Chap. 3, transformation operations can be applied to objects in 3D space. Those operations change the status of objects. Points of interest like vertices are those that undergo the transformation operations. For example, in order to rotate a tetrahedron that is composed of four triangular faces, only its four vertices need to be rotated. The basic 3D transformation operations include translation, rotation, scaling, reflection and shearing. Many publications handled such operations (e.g., Foley et al. 1995, Vince11, Ammeraal07). We will discuss each of these operations in the rest of this chapter.

Notes
- 1.
Note that the positive direction of the rotation about the \(x\)-axis in 3D space is the direction of rotation from the \(y\)-axis to the \(z\)-axis.
