The character TD porfolio of cedric bazillou. Protocol to build a reusable deformation template II: a brute force approach. On August 5, 2012. Over the last months I was busy writing and playing with specialized rigging and deformation nodes for maya . I asked my former mentor at rigging dojo, Brad Clark, some advices on my newly released programming reel. He gave me a really helpful insight on my spline deformer and ask how will it behaves on a full blow creature or character. Tail and cloth removal.

14 April, 2011. Making Animatable Pivot: Part 2. In the first part. We looked at the basics of how pivot works and what is the main challenge in making pivot animatable. In this part we take a look at the implementation detail to build a system which will calculate movement around given pivot point. Here is the hierarchy I am using for this system. So how do we go from our initial state to the final result? Now, let's see the steps to get the final result. Why do we do this? Now, we apply the rotation, w...

Maulik's Technical Art Blog: Freedom of a constrained node

http://leftbulb.blogspot.com/2012/01/freedom-of-constrained-node.html

04 January, 2012. Freedom of a constrained node. When you constrain a transform node using Maya's constraints, it stops inheriting transformations from its top hierarchy. However, if you just connect (for example) translation attributes directly or using simple arithmetic nodes, the connected node continues to inherit transformations from its parent. The difference is because of how a constraint calculates the final output. Let's do a simple experiment. Create a nurbsCircle and a locator. Locator1.pa...

15 October, 2011. Later Mike was kind enough to share the script which gave me insight into his setup. Mine is not as good as his, but I was happy to get the egg rolling :). This challenge sparked my interest in rigid body simulation. Hopefully in the future I will be able to take time into reading more about it (and begin to understand something! Bare essential commands that create Maya's scene. Creating nodes with parenting info. To save the part of the rig as code. My next goal is to be able to an...

10 March, 2012. The biggest challenge and what will actually be the backbone for many of the features is linked with detecting animation events. Exo Switch Constraint also utilizes callback functions to detect keying on the driver (master) node. However, I intend to use it for different purposes and it will allow me to correct any pop at the switching points when animation is updated. There are two options available in Maya to listen on animation update events:. Subscribe to: Posts (Atom).

22 May, 2012. One of the key features of the constraint system I am developing is auto correction of "pop effect" when animation changes. This problem is quite complex due to a lot of different scenarios involved and based on how Maya architecture is designed. User can update keys in the graph editor at any time value, this does not cause the compute since you might be on a frame that is not related to the changes. Hence we have to detect this as animation callback. This means that when animation for a s...

24 June, 2012. Finally, here is a demo of the dynamic multi-way constraint system that I have been working on. Following are some of the features of this constraint system:. Multi-way constraint allows invertible relationship without cycle issues. The driver of the system can be animated. Only one keyframe required for switching the driver. All the follower nodes can be animated while constrained by driver of the system. Auto matching for drivers at switching frames to avoid popping nodes effect.
