Torso Rigging

Hey oh,

Well its a new post, its a new year and the US has a new president.

But im sure most of you have been foaming at the mouth for another post from me. So what do i bring you today.

Well before i go into what i have been upto i thought i’d share with you a tip to reading this blog.

Recently i have discovered google reader (yeah i know im a bit behind the curve), and i have to say its awesome. From any location i can check if there have been updates on my favourite forums, websites and blogs without checking on them one by one.

So if you were one of those fools (like me) who would check websites everyday for updates, subscribe to this this blog and any other site that has an RSS feed.

Anyways…

Just like the previous post, rigging and Houdini is the focus. Dont worry modellers, next post is for you guys.
So with the continuation of translating the Animators Friendly Rigging for Houdini, i have jumped over the first of many many hurdles.

The IK torso rig.

Although this will be the first of many character rigging updates i wont be posting all of the minor milestones.

Just the ones that are interesting to look at and post about.

This is what ive done so far.

This video is an initial overview of the Torso Rig.

The second one goes more into the creation process with refinements to the torso along with early development of the Head and Neck setup.

For google reader users, here is the vimeo link.

Revised Torso Rig with Head and Neck

There is not enough time to talk about what is going on (mainly with the torso rig), that i have decided to make it available for download.
You can get it over at over at odforce.

If you can improve on it, or have any tips to make it more efficient then please let me know. Leave a comment.

Next update will probably be on anatomy and how bloody difficult it is. :)

Also, i still haven’t found anyone who can solve the ball rotation problem. Don’t know what im talking about. See the “Help!” post.

Until then, happy new year. (just in time for the next month :) )

…and don’t forget to subscribe.

Help!

Hey everyone,

I know i said i was taking a little break but i need some help.

I am in the process of creating a ball rig in Houdini. Its the first of many rigging projects. So far its been pretty good. Ive been using Jason Schleifers Friendly Rigging for Animators as my guide. Even though its done in maya it pretty straightforward when translating it into Houdini.

Anyways the first project in the series is a Ball Rig. Here is a quick video demo along with my problem.

So if you can help.

Let me know

Heads up. Im taking a break for a little while.

Hey there blog addicts.

Sorry to have left you for quite a while. (over 30 days)

Anyways as you know im taking a break. I was actually gonna just take the break and not tell ya but i know if i was reading a blog i liked and they took a break without telling me i would be pissed.

So, is there a reason… no, i just felt like it……. of course there is a reason, many in fact, one credible excuse is another thing im working on that looks set to be finaled and when it is i will post a short blog entry about it.

Project-wise though, what am i upto? Well there are two main things. working on the Bee and Sculpting (anatomy).

You might notice i am trying to take my sculpting ability to the next level and so i have started a sort of mastercopy. But the method of creating it is heavily reliant on the knowledge i have gained while reading the Atlas of Human anatomy for the Artist. Although it is a pretty difficult project I am enjoying it throughly and while i am making it i will also be making smaller studies.

As for the Bee. I recently purchased Houdini Apprentice HD. And have been going through not only the Fur walkthrough that was posted a few days ago but also some SOP and CHOPS stuff. I might also be making some pre-vis in the interim for the animation i have planned for the shot.

But I have alot of things i am trying to do at once and so from time to time i really have to dedicate all my energy into one thing, so for the moment i wan to get this study finished and then i will devote some time to the Bee project and other aspects of Houdini (you will probably see a lot of small projects/experiments/concepts).

But the other thing that has been taking up my time has yet to be revealed. I don’t want to build it up or anything but i think it is quite “special” in its own way. It will be coming out this month (i hope) and it should be something that the rest of you enjoy.

so until the model and this new “thing” comes out.

Keep well.

oh and happy thanksgiving for those of you who celebrate it.

Anatomy study 01 – The back

Hey guys, when i created this blog i had tried to make it all about my 3d progression as possible. And while there have been a few instances where i have deviated from this path, some to test out features of wordpress, others just because i took my eye off the ball. AKA plugs (which i still feel are kind of warranted since the number of places for modellers/techies can never be enough).

But every once and awhile a piece of news will float around the internet and shock the world, to the point where i cannot turn away.

Tara Reid has cellulite!!!!!!

(im not sure if its actually cellulite rather than she has had too much liposuction so there is no more fat on here stomach, but it makes for amazing reference for old people with lopsided breast implants, poor girl)

Oh yeah and Autodesk has now bought Softimage.

WTF!!

Can lighting strike twice in the same place twice. Well of course it can. And it has (well not at the same place but at another big company). The guided bolt came down from the gates of Autodesk and struck its competitor between the eyes. I imagine it has been hard to keep this from spilling onto the forums and i must say they have done a pretty good job of it. (And i have recently heard that Softimage staff found out pretty much the same time we did, so we can see why it was so easy to contain).

A lot of people are saying it was expected that Softimage was gonna get bought, but from Autodesk was another thing.

Im not gonna harp on about this since I dont really want to say something stupid…… too late.

One thing i found awesome though, was i said over on odForce “I just want Kim Davidson to say ‘This will never happen to SideFX’ ” , which is a pretty naive and selfish comment, since i understand that sometimes its necessary to sell in order to keep the product and the staff alive.

But 7 hours later after a good nights sleep i woke up to find i had a message from none other than the president of SideFX software. I wont say exactly what he said, but suffice it to say he reassured me of SideFX and Houdini’s future (at least for the time being). I know you can never say never, but along with the fact that SESI is a privately held company, Kim’s passion for Houdini and the craft of CG, i think SESI is pretty safe.

The main thing people really worry about with acquisitions is, possible price increase, lack of innovation, job security (if you work for the target) and possible discontinuation of the product. And although Kim never said it in so many words, i felt the message he was putting out was SESI are in control of their products, their creative path and want to serve their customers to the best of their abilities.

back to business

So anyone notice the title of this blog post. This thing is meant to be about anatomy. I just thought i would take the opportunity to inform people of current affairs (yeah like you dont already know, but it will be cool to look back on this in the future)

Regular readers will probably know i have dabbled a little in anatomy over the year. Little attempts that i spend way to much time on and eventually looks horrible/wrong. Well the main reason it looks so bad is my knowledge on anatomy.

So last week i ordered a book, recommended by Scott Eaton (recent addition to the Artists/Modellers links). “Atlas of Human Anatomy for the Artist”. If there is anyone looking to further their knowledge for artistic purposes GET THIS BOOK. Its a cheap, informative and exhaustive look into anatomy for the artist. (ok thats the plug of the post). Get it now.

In the interim i decided to try learn as much as i could. One area where my skills have always failed me is when i model the back. I just never turns out right.

So i took a few anatomical images and decided to do an ecorche study (which i have never done before). (above right)

Also I wanted to sculpt the image on the left to completion but i knew i didnt have the knowledge or the reference to do it justice, so it will sit quitely on my hard drive untill i feel im upto it.

But eventualy the book. Ive spent the last two days just crawling over the images and text with no discernible order but this morning i decide to put this thing to use.

I did my first sculpture of a back in a very very long time.

It took a little over an hour from a base mesh.

I almost exclusively used the clay tubes brush, and built up the forms and boney structures and i must say it was a joy to watch my model come to life. Its not perfect, in fact i can already see areas that need a lot more work but i think its some of the best work ive done since its rooted in actual anatomy.

I dont expect to create models with the same quality i usually do using this technique and knowledge.

It will take a little time and patience, but already i have cranked something out in an hour of what might take me well over 3, and thats because i knew what i was looking for and not just trying to replicate an image pixel for pixel. So it’s a lot of practice really, its probably the biggest factor that will make you / me faster.

Andrew Loomis: Figure Drawing for all its worth



Along with these images the first thing i did when i decided to get back into anatomy was to look at the resources i already had. A few years ago i remember a few of Andrew Loomis’s books. One in particular that sparked my interest was “Figure Drawing for all its worth”. Alot of useful stuff and is a very good read. Its pretty hard for me to read book on the computer, dont know why but the books were out of print at the time. but i have heard his family are to re-release them (so i will stay tuned for that).

One of the early exercises in the book is on proportion. Many tips in the this section but here is my first attempt of the idyllic man.

I wish i could talk more about this but this post is already getting a bit long in the tooth.

I cant wait to see where this book takes me, im having a lot of fun and learning stuff along the way.

So over the next 50 years you will probably see some more images of my learning process. (since i hear it takes a long time to learn this stuff). I still havent come to that crossroads when modelling figures, should i model that penis or vagina? :P

Hope to post more frequently in the next few months considering it didnt take that long to make these images and i know thats what a lot of you guys like to see.

And yes, the bee project is still alive. It needs some adjustments but i will be furring it up :) .

Take care, bee safe.

About this blog!

In a nutshell, this is where i update work and try stuff out. Think of it like a thread that never gets bumped to page 2.

There will be modelling, rigging, possibly some pre-viz updates ... basically anything i do related to cg will be posted here.

I dont update this blog as frequently as i would like, but one, the updates i do make are quite lenghtly and are packed full of useless goodness and two, this isn't the only place you can find me making a ripple or two.

and that is over at my podcast www.cgroundup.com
