Angie’s revolution

The upcoming Dinosaur Revolution offers some beautiful opportunities to compare visual results across numerous borders: 3D vs. traditional, artist vs. team. Namely, the artist has a blog of her work including bits for the show. Lucky for us, she’s also a talented artist proficient in both traditional and digital techniques. So we can geek out on the differences in her work as it appears throughout all these different venues.

As a side note, I haven’t seen the show, not even the above-linked press materials due to <rant on> dumb-ass regional restrictions which keep me from doing so <rant off> so please read this in the intended spirit of analyzing what I’ve been able to view from the context of my own experiences in 3D productions. Even if I see problems with this and that, I’m overall looking forward to seeing the documentary and acknowledge the effort that’s been stuck into this… I think it’s safe to say from the graphics already released that the Revolution team raised the bar. I’m also going to making assumptions based on the materials and my experience… instead of leveraging each and every time, please allow me to boldly presume and call me out on it in the comments. This begins with the title of this post.

Shall we begin?


Compare these two images, both containing models done by Angie. Both consist basically of the same process, integrating a 3D model into a photographic backplate. The Shunosaurus on the left is from the series, the Hadrosaur on the right she did on her own. Compare the shadow areas on the creatures and background plates, both similar ranges from the camera. That sauropod is much too bright… he’s glowing. The histogram of the selection confirms this… the profile isn’t working. If the animal were a few centimeters large, this might be attributable to subsurface scattering, and the high saturation would encourage such an interpretation. But this is a large animal with thick, non-translucent bones and dense musculature. Alone, Angie got it right. The shadow profiles match quite nicely.

Here we see closer integration of the shadows, with a tendency towards the opposite effect: except for a dominant rim light, our subject of interest tends toward deep shadow while the eyes pop out of the picture as they reflect light. Well, skin also reflects light, so it’s a question of balance… here it tips towards iris.

Where’s this come from, and why do so many documentaries suffer poor lighting when single artists often get it right. Well, a common issue in 3D productions is how the countless, complicated issues intertwine with each other, while the artistic hand-off process often isolates each artist, preventing them from viewing their contribution within the final context in which it will appear.


Are you thinking: “maybe that’s the look they were after”? Perhaps. But the look is determined by the live-action plates. They determine how the viewer will interpret the color of each pixel – what mixture of luminescence, direct and indirect lighting does that rgb value represent? In and of itself, the saturated shadows are wonderful, and this comparison gets even better because Angie has done wonderful paintings of similar subjects. The Edmontosaurus above has very diffuse, saturated shadows as well as a darker shadow cast on the ground. Incompatible? Here it works wonderfully because the overall palette doesn’t dictate an interpretation – its there as a bi-chromatic contrast to bring out those blues. An unskilled adaptation of this effect into photoreal would likely place this fellow in the midst of a forest fire.

So – if you’re upset that the cg documentaries make your favorite dinosaurs drab or day-glo… you know that often it’s not the individual artists to blame, but the conglomerate pipeline.

Yeh, there are many factors that go into TV and film production. Opinions and tastes fly from all directions and artists, in the end, have to furnish the people paying the bills.
On the plus side, it’s also that chain of command that leaves the final responsibility in the lap of the director/producer/executive, which is worth remembering when we think something isn’t up to scratch.

I think it’s not even in the alp of the d/p/e… it should be. But if the pipeline gets too segmented then such discrepancies get pushed down the priority list so far that they don’t even get noticed.

Hi David!

😀 Wow, thanks for this. Really inetersting and really cool you used my dinos! I’m really new to this profession so I find your article wonderful to read. And blush, lol!

I’m glad you like my textures. I’m the nut that is always trying to find interesting patterns in nature and combine them to make pretty designs. Its really my favorite part of the process:)

Thank you again so much and best to you!

[…] On his site, the image is described as a “digital painting / photographic composite“. I’ll go out on a limb and -aside from some painted touch-ups (the egg membranes and such) – call this a 3D illustration with photographic elements used as textures, background elements – the solidity of the volumes, consistency of the details and the lighting all encourage me in making this assumption. Assuming this is the case (despite my father’s warning that to assume makes an ass out of you and me), it allows us an intriguing comparison of toolsets in the hand of a talented artist – as we did with Angie Rodrigues.
