Method, an apparatus and a computer program product for video encoding and video decoding

An apparatus comprising at least one processor and a memory including instructions that, when executed with the at least one processor, cause the apparatus to perform at least the following:

• creating a scene structure for a three-dimensional media content, wherein the scene structure comprises three-dimensional data for objects of the three-dimensional media content;
• determining dependency information for the objects, wherein the dependency information indicates an external factor on which the objects are dependent on for transformation during a runtime process, the external factor relating to a viewer of the three-dimensional media content;
• storing a scene description defining the objects and their dependency information into a bitstream structure;
• and
• transferring the scene description to a renderer,
• wherein the external factor comprises marker information and wherein the external factor is unavailable during the creating of the scene structure.

A non-transitory computer readable medium comprising instructions configured to, when executed with at least one processor, cause an apparatus or a system to:

• create a scene structure for a three-dimensional media content, wherein the scene structure comprises three-dimensional data for objects of the three-dimensional media content;
• determine dependency information for the objects, wherein the dependency information indicates an external factor on which the objects are dependent on for transformation during a runtime process, the external factor relating to a viewer of the three-dimensional media content;
• store a scene description defining the objects and their dependency information into a bitstream structure;
• and
• transfer the scene description to a renderer,
• wherein the external factor comprises marker information and wherein the external factor is unavailable during the creating of the scene structure.
