6.3 - Translating¶

Translating a model changes the model’s location. Translation does not effect the model’s size or orientation. Mathematically, translating is a simple addition. Translating a vertex, (x, y, z), into a new location, (x’, y’, z’), is accomplished by adding a value to each component. Let’s call these translation values tx, ty, and tz. In equation format, translation is performed like this:

x' = x + tx;
y' = y + ty;
z' = z + tz;

Notice that translating by 0 leaves a component value unchanged. Vertices are typically manipulated as a unit, so if you want to translate along one axis and leave the other axes unchanged, use a translation value of 0 for the unchanged axes.
