Abstract

The invention notably relates to a computer-implemented method for designing a 3D assembly of modeled objects. The method comprises rendering on a second computer a 3D assembly of modeled objects by merging a second 3D modeled object with at least one raster image of a first 3D modeled object, the at least one raster image having being streamed from a first computer to the second computer; sending from the second computer to the first computer first data related to the second 3D modeled object for contact computation between the first and second 3D modeled objects; and computing on the first computer a contact between the first and second 3D modeled objects.

First claim

The invention claimed is:

1. A computer-implemented method for designing a 3D assembly of modeled objects, the 3D assembly of modeled objects comprising a first 3D modeled object and a second 3D modeled object, the second 3D modeled object being a geometrical 3D modeled object, the method comprising:
rendering on a second computer the 3D assembly of modeled objects by merging the second 3D modeled object with at least one raster image of the first 3D modeled object, the at least one raster image having being streamed from a first computer to the second computer;
sending directly from the second computer to the first computer first data related to the second 3D modeled object for contact computation between the first and second 3D modeled objects, the first data containing collision geometries of the second 3D modeled object; and
computing on the first computer a contact between the first and second 3D modeled objects.

2. The computer-implemented method of claim 1 , further comprising:
sending from the first computer to the second computer second data for rendering again the 3D assembly of modeled objects according to the contact computation.

3. The computer-implemented method of claim 2 , wherein the first computer sends to the second computer second data related to the first 3D modeled that was determined being in contact with the second object at the computing step.

4. The computer-implemented method of claim 2 , wherein the second data related to the first 3D modeled object comprise geometries of the first object.

5. The computer-implemented method of claim 4 , wherein the second data related to the first 3D modeled object comprise simplified geometries of the first object.

6. The computer-implemented method of claim 5 , wherein the second data related to the first 3D modeled object comprise simplified geometries of the first object and a difference between the simplified geometries of the first object and the geometries of the first object is less than the width of a pixel of the second computer.

7. The computer-implemented method of claim 1 , wherein the second data related to first 3D modeled object comprise two or more depth maps of the first 3D modeled object.

8. The computer-implemented method of claim 1 , further comprising
computing on the second computer a possible contact between the second data and the second 3D modeled object.

9. The computer-implemented method of one of claim 1 , wherein a contact is a collision or a snapping.

10. The computer-implemented method of one of claim 1 , further comprising
moving the second object according to the result of the contact computation.

11. A non-transitory computer readable storage medium having recorded thereon a computer program that when executed by a computer causes the computer to implement a method for designing a 3D assembly of modeled objects, the 3D assembly of modeled objects comprising a first 3D modeled object and a second 3D modeled object, the second 3D modeled object being a geometrical 3D modeled object, the method comprising:
rendering on a second computer the 3D assembly of modeled objects by merging the second 3D modeled object with at least one raster image of the first 3D modeled object, the at least one raster image having being streamed from a first computer to the second computer;
sending directly from the second computer to the first computer first data related to the second 3D modeled object for contact computation between the first and second 3D modeled objects, the first data containing collision geometries of the second 3D modeled object; and
computing on the first computer a contact between the first and second 3D modeled objects.

12. A system comprising:
a processor coupled to a memory and a graphical user interface, the memory having recorded thereon the computer program implementing design of a 3D assembly of modeled objects, the 3D assembly of modeled objects comprising a first 3D modeled object and a second 3D modeled object, the second 3D modeled object being a geometrical 3D modeled object, the computer program causing the processor to be configured to
render on a second computer the 3D assembly of modeled objects by merging the second 3D modeled object with at least one raster image of the first 3D modeled object, the at least one raster image having being streamed from a first computer to the second computer;
send directly from the second computer to the first computer first data related to the second 3D modeled object for contact computation between the first and second 3D modeled objects, the first data containing collision geometries of the second 3D modeled object; and
