Abstract: A method for tracking progress of the construction of objects, such as walls of a building, based on 3D digital representation. Building Information Modeling (BIM) may provide a digital representation of the physical and functional characteristics of a place, such as a building comprising walls and other objects. A method includes capturing one or more images comprising pixels at the site with a camera, providing an image location and direction for each image, and for each image location and direction, rendering the building information model into a virtual projection comprising virtual pixels.

Abstract: The present invention relates to a method for tracking progress of the construction of objects, in particular walls comprised in a building based on 3D digital representation. Building Information Modeling (BIM) may provide a digital representation of the physical and functional characteristics of a place, such as a building comprising walls and other objects.

Abstract: The invention relates to the calculation of 2D images from a 3D model, wherein the 2D images may be generated on a computer device and stored on a server for subsequent display on a client device.
