Abstract: The invention notably relates to a computer-implemented method for modifying a number of graphic cards used for rendering a scene, a graphic card comprising one or more graphic processing units. The method comprises providing a scene that is already loaded in a render engine, the scene comprising at least one graphic data to be used for rendering a view of the scene; modifying an abstract graphic resource for a graphic resource of the at least one graphic data, the abstract graphic resource storing an identifier of the graphic resource for each graphic card, by adding a new identifier of the said graphic resource for each newly added graphic card; transferring, on each newly added graphic card, the said at least one graphic data already stored on one of the graphic cards.

Abstract: A computer-implemented method for rendering, by a GPU, a section view of a 3D mesh in a single pass. The method includes obtaining the 3D mesh having convex polygons, obtaining a clipping plane and rendering the section view of the 3D mesh by: rendering the convex polygons of the 3D mesh, the rendering of the convex polygons of the 3D mesh comprising, for each convex polygon: determining if the convex polygon intersects the clipping plane. If the convex polygon intersects the clipping plane, computing a pair of points on edges of the convex polygon intersected by the clipping plane, storing the pair of points in a GPU-writable buffer. The method also includes rendering the stored pairs of points in the GPU-writable buffer as a set of lines, the rendering of the section view thereby comprising the rendered convex polygons and the rendered set of lines.

Abstract: The invention notably relates to a computer-implemented method for managing a plurality of graphic cards, a graphic card comprising one or more graphic processing units, comprising loading a scene in a Render Engine, the scene comprising at least one graphic data to be used for rendering a view of the scene; creating an abstract graphic resource for a graphic resource of the at least one graphic data, the abstract graphic resource storing an identifier of a graphic resource for at least one of graphic card; copying, on the said at least one graphic card, the said graphic resource of the at least one graphic data; providing to the Render Engine with an access to the abstract graphic resource for handling the said graphic resource.
