![]() So as parts were finished, we were able to slowly put them all back together and build this. We broke up the ideas, the different bits of code, into several different people, so one person was working on volume-preserving parts of the muscle, another was working on the attachment, another was working on the connections of the skeleton, all the different implementation parts. So instead of the skin getting pulled around by the skeleton underneath, they were actually getting pushed around by the muscles performing and moving underneath the skin. The difference with this system is, the muscles underneath were actually moving and pushing the skin around. So the bones underneath drive the skin, and they’re given different weights so they slide around based on how much that bone underneath is moving … So it’s driven by a point inside of the skin. A basic skinning is, you take points on the skin of the character, or the geometry of the character, and attach it to the bones underneath. So as Gollum bends and moves around, the muscles would flex and move like real muscles would, and allow Gollum to get skinned through this muscle system, which was a completely different way of doing things at the time.Įveryone has something slightly different, but it all is based on skinning. When we did Gollum, I was head of the creatures department, and we were writing our own volume-preserving muscle system that allowed us to basically take a skeleton, where we actually built the bones and everything for Gollum, and then put the muscles onto the skeleton and attached them at the proper points. So it’s lots of different areas of technology within Weta that put all that together. Well, the Subsurface technology itself, was actually Ken McGaugh and Joe Letteri who did the majority of the work for that, and they basically took a concept paper that had been written and implemented the math and the information in the paper into a shader-based system, so that we could put it onto the skin of Gollum. What was the process of creating that technology like? ![]() It’s different implementations of it, but it’s the same basic concept that was back on Gollum. It spreads the light as it goes through the surface so you get that skin-like feel. It’s basically like, if you light a wax candle, you see the diffusion of the light through it. Yeah, it’s called Subsurface and we actually got an Oscar for that technology. That was something that had never been done before. I remember reading that the reflection of light on and under Gollum’s skin and the way you could see his veins was one of the biggest innovations that you guys pioneered. Because he was so skinny, you saw all of the muscles moving under his skin. ![]() And because we were inventing technology as we were doing it, it was a huge challenge. ![]() ![]() Up to that point, you’d seen a lot of CG creatures, but none to the level of Gollum, where the detail him an actor on screen, rather than just a scary monster, which is what a lot of the CG creatures up to that point had been. There is one ring to rule them all, indeed, but who's "them"? Here's a breakdown of all the different beings in Lord of the Rings explained.Eric Saindon: When we did Gollum, no one had really done a CG creature mixed with live action that you were supposed to believe was just a creature in the scene. Inspired by history, mythology, philosophy, and world religions, as well as his own experiences fighting in World War I, Tolkien drew heavily from real-life inspirations in creating his fantasy world and its citizens battle between forces of light and darkness. In fact, Tolkien's descriptions, sketches, and detailed notes are so specific he completely set up the visual adaptations to succeed onscreen, even though he never lived to actually see them. The denizens of Middle-earth, even the most marginal creatures who appear only briefly, still have an entire backstory that links with others and makes Lord of the Rings an immersive experience for readers of the books and watchers of the movies alike. J.R.R Tolkien's extensive worldbuilding in Lord of the Rings remains an incredible feat not just in the history of fantasy novels, but literature in general. ![]()
