METHOD FOR VISUALIZING THREE-DIMENSIONAL DATA

摘要

A method for providing a set of data files from a server computer to a mobile client device is disclosed according to at least one embodiment described herein. The method may include providing geometry data in a memory of the mobile client device, the geometry data being associated with a three-dimensional surface in an image scene; selecting data files with texture data for being provided by the server computer, wherein selecting data files is performed by a calculation unit of the mobile client device based on the geometry data and on visibility conditions of the three-dimensional surface in the image scene; and requesting the provision of the selected data files from the server computer to the client device. In some embodiments, the set of data files may include texture data being associated with a portion of the three-dimensional surface in the image scene.

1. A Method for providing a set of data files from a server computer to a mobile client device, the set of data files comprising texture data being associated with a portion of a three-dimensional surface in an image scene, wherein
the image scene is defined by an observation point and a direction and/or angle of view, the set of data files is a subset of data files being stored on the server computer, and each data file comprises texture data in one of a plurality of different detail levels, wherein the method comprises: providing geometry data in a memory of the mobile client device, the geometry data being associated with the three-dimensional surface in the image scene; selecting data files with texture data for being provided by the server computer, wherein selecting data files is performed by a calculation unit of the client device based on the geometry data and on visibility conditions of the three-dimensional surface in the image scene; and requesting the provision of the selected data files from the server computer to the client device.
