    摘要: A method, medium and apparatus determining whether models collide with each other. In the model collision detecting method, medium and apparatus, it is possible to quickly examine whether models collide, and to recognize the collision generated at an arbitrary time, which is not a predetermined collision check time of the models, without missing the recognition of the collision generated at the arbitrary time, by determining whether paths reflecting movement of the model primitives between the current time and a previous time overlap when the model primitives do not collide at the current time, determining whether the model primitives collide with each other at an arbitrary time between the current time and the previous time when the path primitives overlap each other, and recognizing that the models collide with each other at the arbitrary time when the model primitives collide with each other at the arbitrary time.

    摘要: A graphic data encoding method and apparatus generating a bitstream by encoding a header having at least one piece of first information determined in consideration of a predetermined graphic profile from among multiple pieces of encodable first information; and encoding a payload having at least one piece of second information determined in consideration of the predetermined graphic profile from among multiple pieces of encodable second information. A graphic data decoding method and apparatus decode the generated bitstream. Irrespective of the functions that can be performed by the graphic data encoding apparatus and the functions that can be performed by the graphic data decoding apparatus, the graphic data decoding apparatus, which is in accordance with a graphic profile, can completely restore a 3D mesh model described in the bitstream generated by the graphic data encoding apparatus that is satisfactory to the graphic profile.
