Systems and methods for three-dimensional (3D) modeling are described. Embodiments of the inventive concept are configured to receive manipulation input for editing a scene in a static 3D modeling application, perform a physics simulation based on the manipulation input, wherein the physics simulation comprises a plurality of simulation steps performed based on a set of motion constraints configured for the static 3D modeling application, and apply a change to the scene in the static 3D modeling application based on the physics simulation.
