Material to learn alternatives to Blendshape facial animation. Curves/etc.

[dragonlair81]

you can read about the setup used here. http://www.cane-toad.com/tuteRig_Facial.htm. They use a bone based setup and that might help.

my bad didn't read all of your message can't think of anything but cane toad.

Well, what is it that you're wanting to know exactly? You can pretty much apply your knowledge from the setup techniques that are employed for setting up the rest of the body and apply them to the face, shouldn't be that big of a deal. Like I said, post up specific questions and I'm pretty sure someone out there will have an answer for you.

Lol dragonlair, I've done that before, np, link is always good anyway.

seven6ty, I'd like to know of in-depth instructional products or courses or tutorials dealing with stuff other than blendshapes.

Have found stuff such as the following:
http://sfdm.ca.scad.edu/vsfx/facult...thesis/WonByun/ (http://sfdm.ca.scad.edu/vsfx/faculty/jopasqua/Gradthesis/WonByun/)

or articles on Voiceworks being used with 20-30 bones for games, etc.

I am searching for in depth material on learning alternatives to blendshapes. Great to have canetoad rference, but am looking for something more in depth. Haven't found anything yet.

Blendshape material is everywhere, not surprising because it is on the lowest rung of the facial quality.

Wellllll, like I said, if you have a specific question about it I'm sure we can answer it, there aren't very many joint based tutorials out there, aside from the cane toad one. It all kind of depends on if you're talking about rigging a mouth, eyebrows, the head for squash and stretch or what your goal is.

And I definently wouldn't say blendshapes are the lowest rung in terms of quality. If used correctly they can be extremely powerful and just as powerful as joints or any other method.

You're cracking me up, but just for fun, here is an undeniably specific question:

Where can one locate and or obtain in-depth instructional products or courses or tutorials dealing with stuff other than blendshapes for facial setup besides in the workforce?
(Beyond canetoad)

Please provide a specific answer ;)
( Truly appreciate your help on all topics seven6ty, no offense, couldn't resist though. Here's hoping there is something other than canetoad.)

I know that Alias has some Hyper-Real DVDs, including one for Hyper-Realistic Facial Animation (all under the "Advanced" skill level section):

http://www.alias.com/glb/eng/products-services/learning_tools.jsp

However I haven't seen it so I can't tell you anything beyond that - opinions on the content, anyone?

[skullofbone]

Deadtown_Ripper, thanks for checking in. From what I've read of the reviews, it seems that the main focus of the Hyper Real Facial Setup is blendshapes. Thank you though, because others may still be interested in the Series. (If the reviews failed to mention major instruction dealing with alternatives that'd be amazing, but cool in this case)

The Hyper-real facial dvd does deal mostly with blendshapes, but it covers some high end techniques regarding them. It also goes over a sweet cluster setup, which in the context of the tutorial is supposed to work with blendshapes, but could certainly be used on it's own.

Cane-toad's the only tutorial I can think of online.....

[M.E.L.]

blendshapes
clusters
wire deformers
muscle influence objects
joints

subclasses:

blendshapes
|_tension mapping

clusters
|_path constraints
|_set driven keys

wire deformers
|_set driven keys
|_animated CV's
|_skinning to facial bones

muscle rigs
|_skinned to facial bones
|_constrained to facial bones
|_sdk'd shape settings
|_expression/node driven offsets

joint based rigs
|_facial mocap
|_set driven keys
|_constraints/blending
|_node based area of influence (jointA pulls jointD * 10%, jointF pushes jointZ * 6%)


that's just skimming off the top of my head the varying setups that could be used... faces are the most complex area of any character related work, you can get into hundreds if not thousands of ways to set things up and do them.
