Required Constructions for Polygon Mesh
There are three types of important mesh constructions which are –
- Box Modeling: One of the most widely used techniques in 3D visualization is box modeling to use at critical time, which enables users to construct their model’s fundamental forms. After that, the user may use that rough draught to shape the final, intricate framework for the required and functional design.
- Extrusion Modeling: The primitives of basic shapes like cubes, cylinders, pyramids, and much more are the first step in the extrusion modeling process to develop the overall process, and they let the user add geometry to start sculpting a mesh. A user can produce a 2D image that can be converted into a 3D object as per requirement by using this method.
- Common Primitives: The three-dimensional objects can be constructed from the initial primitive materials. Cubes, cylinders, pyramids, spheres, cones, and other fundamental shapes are basic or functional examples of primitives. This method can be used to make the user require intricate 3D things.
Polygonal Modeling in Computer Graphics
Polygonal modeling is a very beneficial technique that is used in 3D computer graphics to model objects by utilizing polygon meshes to approximate or represent their surfaces. For real-time computer graphics, polygonal modeling is the preferred technique for its features, since it works well with scanline rendering. NURBS surfaces, subdivision surfaces, and equation-based (implicit surface) representations, which are very useful and seen in ray tracers, are some more approaches to modeling 3D objects. As they would have no use for the models, their required investments would yield meager returns to process overall tasks.
