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 rendering the global illumination of a three-dimensional scene. The method comprises providing a 3D scene that comprises of a set of triangles and one or more direct light sources, determining that each triangle of the set has an area that is below a threshold, assigning to each triangle of the set a radius of influence using a probability law, obtaining a subset of triangles by filtering out the triangles according to their radius of influence, rendering the three-dimensional scene by lighting its set of triangles, the triangle of the subset of triangles being used as indirect light sources according to their radius of influence.
