摘要： In aspects, methods and apparatus are provided for generating a haptic effect for a three-dimensional (3D) environment that is experienced virtually by a user. The methods may be performed by a processor, and includes receiving media data that describes the 3D environment, wherein the media data includes haptic data which describes a haptic characteristic associated with at least one object, structure, or event in the 3D environment. The method further includes performing a haptic decoding operation and a haptic rendering operation. The decoding operation may include extracting the haptic data from the media data. The haptic rendering operation may include generating a drive signal and communicating the drive signal to a haptic output device to cause the haptic output device to generate a haptic effect at a user peripheral device. Numerous other aspects are provided.
