I was reading about the "bones" tool in Flash CS4, and the IK library that comes with it, but I don't have access to CS4...so I'm wondering if there is a smilar tool and library for CS3 users, who may want to create these effects with Actionscript. ...
Hi I am trying to implement Inverse Kinematics on a 2D arm(made up of three sticks with joints). I am able to rotate the lowest arm to the desired position. Now, I have some questions: How can I make the upper arm move alongwith the third so the end point of the arm reaches the desired point. Do I need to use the rotation matrices for...
I am given coordinates of two points in 3-D viz. shoulder point and object point(to which I am supposed to reach). I am also given the length from my shoulder-to-elbow arm and the length of my forearm. I am trying to solve for the unknown position(the position of the joint elbow). I am using cosine rule to find out the elbow angle. Here ...
My objective is to paste together several ( a lot, actually ) armature animations, each in a separate symbol. I have no idea how to do it, armature layers are a bit... strange. So i see only one solution: convert it to a regular layer. ...
I am trying to do inverse kinematics for a serial chain of arbitrarily many links. In the following paper, I have found an example for how to calculate the Jacobian matrix. Entry (i, j) = v[j] * (s[i] - p[j]) where: v[j] is the unit vector of the axis of rotation for joint j s[i] is the position (int world coords?) of jo...
