We used graphicslib3D in the first edition of our book. Specifically, graphicslib3D is a math library we had previously developed for our graphics courses, and so we used it in the first edition.
But long ago we switched to JOML and no longer support graphicslib3D. Our 2nd and 3rd editions of the textbook all use JOML instead. JOML has much richer set of tools, has much better performance, and is better maintained.
