“…This technique allows rendering full models and limits considerably the number of graphic primitives constituting the complex scenes. Further improvements of these techniques are presented in (Ragragui et al, 2018;Ragragui et al, 2020;Ouazzani Chahdi et al, 2021).…”

“…The problem of revolution mapping is that the revolved object is created without any microrelief effect, so it does not take into account their realism. From this observation, the solution is to combine bump mapping with revolution mapping, which is called revolution-bump mapping (Ragragui et al, 2018).…”

Creating 3D computer-generated surfaces has long been a difficult challenge in computer graphics, particularly when portraying massive landscapes with extremely detailed surfaces in real-time. Despite significant advances in computer vision in recent years, there is still a great demand for improved realism and the capacity to edit computer-generated 3D surfaces in real-time. We propose three scalable and faster algorithms for creating extended, beveled, and chamfered patterns using only two textures and a simple shape box. The proposed techniques produce visually pleasing results in real-time while retaining optimal rendering performance and without increasing the mesh density of the shape box.

Per-pixel extrusion mapping consists of creating a virtual geometry stored in a texture over a polygon model without increasing its density. There are four types of extrusion mapping, namely, basic extrusion, outward extrusion, beveled extrusion, and chamfered extrusion. These different techniques produce satisfactory results in the case of plane surfaces, but when it is about the curved surfaces, the silhouette is not visible at the edges of the extruded forms on the 3D surface geometry because they not take into account the curvature of the 3D meshes. In this paper, we presented an improvement that consists of using a curved ray-tracing to correct the silhouette problem by combining the per-pixel extrusion mapping techniques and the quadratic approximation computed at each vertex of the 3D mesh.
