An example device for retrieving media data includes a memory configured to store media data; and one or more processors implemented in circuitry and configured to execute a presentation engine, the presentation engine being configured to: receive streamed media data representing a virtual three-dimensional scene including at least one virtual solid object; receive object collision data representing boundaries of the at least one virtual solid object; receive camera movement data from a user requesting that the virtual camera move through the at least one virtual solid object; and using the object collision data, prevent the virtual camera from passing through the at least one virtual solid object in response to the camera movement data.
