Preparing a translation matrix

Basic operations that can be performed on 3D models include moving the objects in a desired direction for a selected distance (number of units).

How to do it...

1. Prepare three variables of type float named x, y, and z, and initialize them with the amount of translation (movement distance) applied to the object along the x (right/left), y (up/down), and z (near/far) directions respectively.
2. Create a variable of type std::array<float, 16> named translation_matrix that will hold a matrix representing the desired operation. Initialize elements of the translation_matrix array with the following values:
   • All elements initialize with a 0.0f value
   • 0^th, 5^th, 10^th, and 15^th elements (main diagonal) with a 1.0f value
   • 12^th element with a...
