US 10,593,125 B2 · 2D-3D sculpture paintings

Abstract

We disclose a method for synthesizing by computer an artwork where 2D and 3D contents are integrated within a same composition. Such an artwork creates plausible effects for the viewers by showing a different relationship between 2D and 3D at each viewing angle. Methods are proposed for ensuring the continuity between the 2D and the 3D parts in terms of mesh geometry and reflected colors. The user selects from a given scene a region of interest (ROI) to be reproduced in 3D. A flat rendering grid is created that matches the topology and tesselation of the ROI. The ROI is attached to the rendering grid. To enhance the continuity between the 2D and the 3D parts of a scene object, the 2D part of the object can be represented as bas-relief. Designers can create 2D-3D sculpture paintings for decoration, exhibitions, and homes.

Dependent claims

A method for composing by computation a 2D-3D piece of art comprising a scene with a salient object, where the portion of scene surrounding said salient object is rendered on a rendering plane as a flat 2D reproduction, and where the salient object is reproduced partly as flat, partly as bas-relief and partly as 3D, the method comprising the steps of:

(i) intersecting the salient object surface with a cut plane thereby obtaining on one side of the cut boundary a region of interest of the object which forms the part of the salient object to be reproduced in 3D,
(ii) aligning and smoothing the cut boundary of said region of interest along the cut plane,
(iii) creating a grid on the rendering plane and a hole on this grid whose border matches the cut boundary of the region of interest,
(iv) attaching the region of interest to the rendering grid at the border of said hole,
(v) adding a bas-relief profile to a part of the salient object outside of the region of interest and ensuring smoothness between flat, bas-relief, and 3D parts of said salient object.

A computing system for composing by computation a 2D-3D piece of art comprising a scene with a salient object, where the scene portion surrounding the object is rendered as a flat 2D reproduction, and where the salient object is reproduced partly as flat, partly as bas-relief and partly as 3D, the computing system comprising software functions operable for:

(i) intersecting the salient object surface with a cut plane thereby obtaining on one side of the cut boundary a region of interest of the object which forms the part of the salient object that is to be reproduced in 3D,
(ii) aligning and smoothing the cut boundary of said region of interest along the cut plane,
(iii) creating a grid on the rendering plane and a hole on this grid whose border matches the cut boundary of the region of interest,
(iv) attaching the region of interest to the rendering grid at the border of said hole,
(v) adding a bas-relief profile to a part of the salient object outside the region of interest and ensuring smoothness between the flat, bas-relief and 3D object parts.
