US 11,455,779 B2 · Visualization of massive 3D models in interactive editing workflows

Abstract

In example embodiments, techniques are provided for visualizing a 3D model in an interactive editing workflow. A user modifies one or more elements of a model of the 3D model, by inserting one or more new elements having geometry, changing the geometry of one or more existing elements and/or deleting one or more existing elements having geometry. An updated view of the 3D model is then rendered to reflect the modification to the one or more elements in part by obtaining, for each new element or changed existing element of the model visible in the view, a polygon mesh that represents geometry of the individual element, obtaining a set of tiles that each include a polygon mesh that represent collective geometry of a set of elements intersecting the tile's volume, displaying the polygon mesh for each new element or changed existing element, and displaying the set of tiles while hiding any deleted or changed existing elements therein.

Dependent claims

A method for visualizing a three-dimensional (3D) model in an interactive editing workflow wherein a volume of the 3D model is subdivided into a plurality of tiles, comprising:

modifying, by an application executing on one or more computing devices, one or more elements of a model of the 3D model, wherein the modifying inserts one or more new elements having geometry, changes the geometry of one or more existing elements and/or deletes one or more existing elements having geometry;
and
rendering, in a user interface of the application shown on a display screen, an updated view of the 3D model to reflect the modification to the one or more elements by
obtaining, for each new element or changed existing element of the model visible in the view, a polygon mesh that represents geometry of the individual element,
obtaining a set of tiles from the plurality of tiles that each include a polygon mesh that represents collective geometry of a set of elements intersecting the tile's volume,
displaying the polygon mesh for each new element or changed existing element, and
displaying the set of tiles while hiding any deleted or changed existing elements therein.

4 more elements

A non-transitory electronic device readable medium having instructions stored thereon, the instructions when executed by one or more processors of one or more computing devices being operable to:

modify one or more elements of a model of a 3D model, wherein the modification inserts one or more new elements having geometry, changes the geometry of one or more existing elements and/or deletes one or more existing elements having geometry;
obtain, for each new element or changed existing element of the model visible in a view of the 3D model, a polygon mesh that represents geometry of the individual element;
obtain a set of tiles from a plurality of tiles that subdivide the 3D model, the set of tiles to each include a polygon mesh that represents collective geometry of a set of elements intersecting the tile's volume;
display the polygon mesh for each new element or changed existing element;
and
display the set of tiles while hiding any deleted or changed existing elements therein.
