SKULLS!!!

Today I went with a bunch of friends to the California Academy of Science's "Skulls" exhibit in San Francisco. If you know anything about me (which I'm hoping you do if you're reading this blog), then you know that I'm fascinated with animals and their anatomy. Bones in particular I've always found fascinating, and since I've always gravitated toward doing art related to faces and facial expressions, skulls are kind of my favorite.

While there, a bunch of us did some sketching. I'm not particularly happy with any of the sketches I came out with but it was a lot of fun just sort of roughly block stuff out. I was enjoying the process a lot, which is nice.

The exhibit was fantastic. There was a large variety of things, and they  put many diverse animals right next to each other to hammer home just how much variety can be seen in the same basic layout. There were mostly mammals, but plenty of birds, reptiles, and fish as well. I was basically like an ADD kid in a candy shop, overstimulated by the amount of stuff they had in there; constantly getting distracted from the cool thing I was looking at by another equally cool thing that I caught out of the corner of my eye (this is also what I will blame my lackluster sketches on  - I was too excited by the plethora of things to really focus on any one subject). Overall lots of neat things! I highly recommend it! :D

Here are some bonus images:

Tapir and Sea Otter. Best of friends?

You should ALL go if you can! There is PLENTY of things I haven't spoiled here, like Elephants, and a WALL of sea-lion skulls, that challenges you to use your comparative anatomy skills to pick out the non sea-lions. Oh, and the rest of the museum is really pretty great too. But don't take my word for it! BA-DUM-BUM!

Saturday Drawing in the Park

Just some misc sketches from today:

I started by drawing actual things that were in front of me....

...but of course ended up just drawing cartoon animals from my head. Here's a walrus being photo-bombed by a cat.

And here's a goof of an elephant seal. The snake does not approve of his goofiness...

That's enough pinnipeds for now.

Longisquama

Howdy Folks,

  Contributed this guy to the header for our 90 minute comics site you might have heard me talk about. I definitely spent too much time on him for the resolution of that header, but It's not everyday one draws Triassic Reptiles (unless, that's like, your thing - then I guess you do....but I certainly don't on a regular basis).

Anyway, thought I'd post a larger res version here (click for higher res). Oh, and the big beautiful Zero he's climbing on was drawn by Nate Shaw, just so we're all clear.


Until the Next Time!

Hadrosaur Sketches

It's been a while since I've posted anything so I thought I'd post some of these rough sketches I did a few months ago. I was working on some Hadrosaur designs. Not trying to restore any particular species, but have been referencing things like Gryposaurus, Kritosaurus, and even a little bit of Tethyshadros. I was just exploring shapes to help bring out character.

This was some visual development of a possible comic idea I had. We'll see if I get around to doing anything with it. Also, just for kicks, here is another character sketch:

Enjoy,

Tupandactylus VI: Final Product

Alas the time has arrived! Sorry it's been a while since I've posted on this guy. I think the difference between the last image posted and this finished animation will speak for itself!




I also decided to do this making-of video. Houdini's procedural nature allowed me to show off some of this process really easily, so I took the time to edit this together:



I hope you enjoy! I really had a lot of fun delving into Pterosaur anatomy. Unfortunately due to time and other obligations at work, I cut the shot in half. The second half would have showed some quadrupedal walking and launching. The motion is all blocked out, but that's where it must remain for now (sigh). I hope sometime in the future I get the chance to revisit it. I really want to play with such a bizarre animal walking. Despite the cut, I'm really excited about the project! Thanks for tuning in!

Tupandactylus IV

I spent the past week taking the time to paint and sculpt the Tupandactylus model. I initially started by trying out 3D-Coat thanks to a recommendation I received.  I painted the diffuse color map in 3D-Coat, and there is a lot about the program that I really like a lot. It's very easy to pick up, and there are a lot of nice tools. When it came to sculpting, I had so much trouble getting  it to properly export a displacement map. It was also crashing constantly, which was incredibly surprising, because of the specs of the machine I was working on. After about a day of trying to get it to work, I then turned to ZBrush for the sculpting which worked spectacularly. It was like reuniting with an old friend in a way, considering it's been almost a year to the day since I've used it last.

For sculpting reference, I used a number of diagrams of proposed pterosaur musculature as a loose guide. I also threw in my own knowledge of crocodylian musculature to help sculpt in the major muscle masses. A lot of the fine detail was influenced by birds, a few minor details from bats, and even some influence from lizards. I looked at a lot of pelicans, cormorants, parrots, and condors to try to get some nice face wrinkles. There's a lot of detailed skin texture which is kind of difficult to see on the wider images (click for larger view).

Now I need to work on getting the diffuse, displacement, and normal maps to properly transfer to Houdini so I can move on from texturing.

Tupandactylus III

A lot of cool stuff going on with this guy. I've done the first round of blocking animation, and then moved on to some visual development. I've been working on lighting/shading/rendering as a break from animation. Primarily, I've been playing a lot with subsurface scattering. I set up the shot featuring this guy so that he will be lit extensively from behind. I want to do this so that I can play with the subsurface on the wing membranes, exposing tints of the subdermal layers and blood vessels underneath.

Here is a test image of the subsurface:

I was able to control the subsurface scattering through texture maps, where I painted in the veins and arteries that will subtly shine through the skin in certain areas:

Keep in mind the shading in the top image is from the subsurface alone. That's the tint that's going to shine through. There is just a plain brownish shader (with no displacement) applied to the model at this time. The reason for this is I had a lot of look-development to do in order to figure out what I want this guy to actually look like before texture painting can begin.

I did some visual development by painting over a black and white render of the Tupandactylus with the brush mode set to overlay. After doing a couple of concept paintings, I mixed and matched the various layers to get many more variations. I'm not yet sure which one I'm going to pick, but here are the concept paintings (click to enlarge):

 I looked at a lot of reference imagery of everything from parrots to frogs to butterflies. I often see a lot of pterosaur restorations with the exact color patterns of various types of birds. I wanted to avoid this trend, by attempting to find something that feels like it could have appeared in nature while also feeling unique to this type of animal. I was also trying to make sure the crest stands out as a display device, while also having the entire animal's color palette feel homogeneous.

Now that this has been done, I need to decide on a design, and get to painting. I think this next week I'm going to jump back to animation again, as well as hopefully get those pycnofibers started.

Tupandactylus II

Continuing on my Tupandactylus, I fixed up the model, created some UV's, rigged, and skinned the critter. The key for the rig was making it so it would be able to work both in the air, and in the pterosaur quadrupedal stance. I think it works rather well.

Next I'm going to do some animation to test the rig further, and make any minor adjustments I may need in the skin weighting before I get to texturing and 'pycnofiber' generation (via the fur tools).

Tupandactylus I

For an individual portfolio-building project at work, I've decided to build a full creature in Houdini; doing everything from modeling to animating to rendering. I've also taken this opportunity to do something I've wanted to do for quite some time: build a pterosaur. More specifically, the  tapejarid, Tupandactylus imperator.

To prep, I've been doing a lot of reading about pterosaur anatomy; mostly Dr. David Unwin's Pterosaurs: from Deep Time, as well as from other sources such as http://pterosaur.net/ and portions of various papers and websites. Due to the lack of time I have to complete this, I'm obviously not going to hit the books nearly as hard as I did for my Master's Thesis. I just have been casually reading and using my modeling sessions as a way of testing my understanding. It's been fun so far. I want it to be authentic enough, and true to the animal without killing myself over every minor anatomical detail.

Here are some images of what I have thus far. So far I've completed the base model (much more detail will eventually be sculpted in), and I've laid out the bones which will be used for the control rig.

First the model:

...and the bone layout:

I took my time with the model to try to make sure I was able to create it in a way that would work for both the flying and walking motions. Being conscious of this, before spending the time in connecting the model to the bones, I first adjusted the skeleton into a quadrupedal stance to make sure the dimensions of the animal would work.

This has been a fun project so far, and I'm excited to get a working rig. Painting the skin texture and adding the "pycnofibres" should be fun as well :P

As always, comments, suggestions, feedback, etc. are welcome!

The Perpetually-Projectile-Vomiting Dinosaurs of Santa Monica

Sorry for the lack of posts lately. I've been busy with relocating to Los Angeles, and settling in with a new job. I'm currently working at Side Effects Software, as a Character Animation Intern; working on a short film that is being produced internally.  I do have more drawings and even an animation test to eventually post, but first things first...

The office I'm working on is right on the Promenade in Santa Monica, and right outside, there are two Ornithischian dinosaur fountains, which I absolutely adore.*

I have always found it peculiar that there are a plethora of fountains in the world where the water spout emerges from the depicted animal's mouth. Every time I see this, I just can't help but laugh to myself. Here is another image.

The reason I find this so humorous, is because, if these figures were indeed alive....they would be in a horrifically uncomfortable state of perpetually-projectile-vomiting, which is hilariously ridiculous. The above Stegosaurus fountain therefore inspired me to realize this bizarre concept with the following digital painting (click for higher resolution):

I'm glad I got that off my chest! Now I hope every time you see an animal fountain, you imagine what it would look like if it were alive, and puking all over the place.

* Down the street there are two sauropods as well; both a Brachiosaur and Diplodocid - and they almost look like they're about to beat the crap out of each other

Look what I dug up...I completely forgot about this...
