This standard 21/30390397 DC BS ISO/IEC 23488. Information technology. Computer graphics, image processing and environment data representation. Object/Environmental Representation for Image based Rendering in Virtual/Mixed and Augmented Reality (VR/MAR) is classified in these ICS categories:

• 35.140 Computer graphics

The primary purpose of this document is to provide an image-based representation concept and to specify the required elements. This document specifies an image-based representation model that represents target objects/environments using a set of images and optionally the underlying 3D model for accurate and efficient objects/environments representation at an arbitrary viewpoint. It is applicable to a wide range of graphic, virtual reality and mixed reality applications which require the method of representing a scene with various objects and environments.

This document:

• defines terms for the image-based representation and 3D reconstruction techniques;

• specifies required elements for the image-based representation;

• specifies a method of representing the real world in the virtual space based on the image-based representation;

• specifies how visible image patches can be integrated with the underlying 3D model for more accurate and rich objects/environments representation from arbitrary viewpoints;

• specifies how the proposed model allows multi-object representation;

• provides an XML based specification of the proposed representation model and an actual implementation example (Annex A)
