Rendering potential collisions between virtual objects and physical objects if animations are implemented. A method includes receiving user input selecting a virtual object to be animated. The method further includes receiving user input selecting an animation path for the virtual object. The method further includes receiving user input placing the virtual object to be animated and the animation path in an environment including physical objects. The method further includes, prior to animating the virtual object, displaying the virtual object and the animation path in a fashion that shows the interaction of the virtual object with one or more physical objects in the environment.
