This is an unusual question regarding rendering of a font with a specific 3D-esque style in LaTeX, XeLaTex, or any other TeX flavor.
I was looking at some fonts the other day and I came across one of which I am very fond:

There are many beautiful examples of this font, such as:

However, each of these examples has a 3D quality to it. The font is both shaded and colored, which make it look tolerable. In regular, two dimensions it looks like this:
Which is hardly anything to write home about. My question is simple: how can I get LaTeX, XeLaTeX, or any other flavor, to render a font with a 3D effect like the one in the pictures above? Is it possible or would it have to be done in an image editor?
Unfortunately, Googling has yielded poor results and I have began to think that it may be hopeless, though documents like this one make me think it may be possible.
[EDIT]
For further clarification, the 3D effect that is of interest is the shading on the characters of the font. In the first image, this effect can be observed on the letters of the word "Octant", which shades each character on the right side, as though there is a light source to the left. Another example of the effect is the words "Griffin & Quayle" in the second image.
