METHODS AND SYSTEMS FOR PHYSICALLY-BASED RUNTIME EFFECTS

One exemplary embodiment involves receiving input defining an inverse kinematics hierarchy for an object to be displayed in an application under development. The exemplary embodiment further involves receiving input indicating a physical parameter applicable to the inverse kinematics hierarchy. The exemplary embodiment further involves producing a package defining the application under development. The package comprises a description of the physical parameter and code that, when executed or interpreted, provides a physics engine configured to calculate a physical response of at least a portion of the inverse kinematics hierarchy using the description of the physical parameter.
