Visual comparison between forward kinematics (FK) and inverse kinematics (IK).

Summary

[edit]
Description
Español: Dependiendo de cómo afecten los movimientos de los huesos, dividimos la cinemática en:

1. Cinemática de avance (FK): Las transformaciones de los huesos siguen una jerarquía lógica. La cadena de huesos/controladores hacen que el hueso “padre” mueva al hueso “hijo”. Es decir, si rotamos un hombro, el brazo entero se mueve; si rotamos el codo, el brazo se mueve desde el codo hasta la mano; si rotamos la muñeca, se mueve la mano. Es el perfecto mecanismo para crear arcos en los movimientos, y se tiene un gran control de las formas implicadas en el movimiento del modelo.

2. Cinemática inversa (IK): Calcula cómo deben de moverse (transformarse) la cadena de huesos/controladores, basándose en la raíz y en la punta (o final) la de la cadena. Es el mecanismo generalmente utilizado cuando el modelo está interactuando con objetos.


English: Depending on how the movements of the bones affect the body, we divide kinematics into:

1. Forward kinematics (FK): The transformations of the bones follow a logical hierarchy. The chain of bones/controllers causes the "parent" bone to move the "child" bone. That is, if we rotate a shoulder, the entire arm moves; if we rotate the elbow, the arm moves from the elbow to the hand; if we rotate the wrist, the hand moves. It is the perfect mechanism for creating arcs in movements, and it provides great control over the shapes involved in the model's movement.

2. Inverse kinematics (IK): It calculates how the chain of bones/controllers should move (transform), based on the root and the tip (or end) of the chain. This is the mechanism generally used when the model is interacting with objects.
