After Effects Rigging Tutorial: Good Joints - Automatic Corrective Joints for Rigging in After Effects from James Hazael on Vimeo.

Sick and tired of designing characters with circular joints. Be bound by the constraints of geometry NO MORE! Using the magic of after effects expressions you too can create rigs with automatic corrective joints. GOOD JOINTS.

EXPRESSIONS USED:

a = thisComp.layer("Null_A").toWorld([0,0,0]); b = thisComp.layer("Null_B").toWorld([0,0,0]); c = thisComp.layer("Null_C").toWorld([0,0,0]);

v1 = normalize(a-b); v2 = normalize(c-b); angle = radiansToDegrees(Math.acos(dot(v1,v2))); if (cross(v1,v2)[2] < 0) angle = 360 - angle;

Expression by Dan Ebberts (forums.creativecow.net/thread/227/23341) ___________________________________________________

var ctrlValue = Control value...; var ctrlMin = 0; var ctrlMax = 100; if (numKeys >= 2) { var t = 0; var beginTime = key(1).time; var endTime = key(numKeys).time; if (ctrlMin > ctrlMax) { t = linear(ctrlValue, ctrlMin, ctrlMax, endTime, beginTime); } else { t = linear(ctrlValue, ctrlMin, ctrlMax, beginTime, endTime); } valueAtTime(t); } else value;
