Popular 3D Modelling Techniques Used In Games

3D modelling is a complex and costly process but no game is made without its use. Various 3D modelling tools come free of cost and are always in the access of artists to project realistic animation designs and models. This blog is specially written to shed light on the most common and prominent 3D modelling techniques, let us get started with the details right away –


Image-Based Modeling


Image-based modelling refers to the modelling process requiring two-dimensional images to create real-time three-dimensional object models. These created game models are consistent in texture and geometric shapes mapped over each other. You only require visually clear images to transform them into your favourite game model. The technique allows computers to acquire a better understanding of videos or images. With its help computers can easily interpret visual information like human beings.




It is a simple 3D modelling technique that allows two-dimensional images into the 3D objects. The method uses an algorithm to allow seamless transform pictures into detailed 3D assets. The images need to be shot from all angles to make the object look more real. The technique is rather less costly and allows the long-term processing of 3D objects manually.


Digital Sculpting




This is a newly coined technique that has gained immense popularity in such a short period. Digital sculpting is considered vital when it comes to photorealistic asset creation. The process is of sculpting is achieved by using a list of digital tools. Various software products such as Zbrush and Blender, serve impactful in creating realistic models as if they were made of clay. The technique allows the creation of real-time assets in a mesh-based geometry containing thousands of polygons. 3D sculpting or digital sculpting is when an artist begins the modeling process by sculpting a 3D object on a computer with the help of digital clay-like material. Latest software tools with cutting edge brushes and tools prove useful in applying effects such as pinch, pull, push and smooth the surface. It further assists in creating detailed sculptures that are real-life carbon copies of objects and textures.


3D Scanning




This specific 3D modeling technique is orthodox in the way it approaches the whole modeling process. For performing accurate 3D modeling you require a three-dimensional scanner. The need is to collect information about an object from multiple angles without missing out on any aspect. To enable the construction of a perfect 3D model you can make the most from 3D scanning. This method is exceptionally good for the portrayal of facial expressions of game heroes. This is due to its capability to create 100% precise polygonal or NURBS mesh. However, the more the benefits the more difficulties to encounter especially when mirroring, shiny, or transparent object processing by a 3D scanner.






Non-uniform rational basis spline is a quite frequently utilized mathematical model. It proves helpful in creating complex surfaces n a simple manner. NURBS mesh relies on 3D artists for modeling curves and edges to generate a smooth surface. The surface is created by lofting between a selected degree of the curve and control points. The method is quite fast to effectively draw a 3D radial object. The artist only needs to be precise with contour placements while the software pulls the rest of the job.


Procedural Modeling




Procedural Modeling relies on the software capacity that the artists use to create enticing 3D models. Model types can be created just by selecting a game location and landscape environment. This drastically reduces the time consumption and skills required altogether from an artist. Environment modeling packages like Terragen, Bryce, Vue give access to an infinite preset of objects inside the mesh such as trees, animals, grass, and buildings. In addition, it allows careful selection of essential parameters of terrain distance, elevation range, and fallout density. Specialized tools like SpeedTree gives the option of generating a variety of unique object models. By using this tool you can render exceptional details of bushes and trees. Certainly, this feature can help you achieve a flawless look throughout the game location and environment.


Box/Subdivision Modeling




You would’ve heard about this beginner-level technique known as Box Modeling. The technique relies on initially reshaping the objects by manipulating the form and size of the object model. The method is simple and can be carried out by a non-professional as well. This is because the technique does not involve any complex details added to the created asset. This is the reason why the subdivision is a popular method used to add subtle details to the final production model. Initial low-polygon mesh s subdivided into several smaller polygon sets to further refine the modeling process by adding a bigger polygon count number. The process is repeated over and over again until desired appearance results of the object model are obtained.


Edge Modeling




Edge Modeling is yet another exciting polygonal technique to create an object asset in real-time. It is based primarily on making a guided outline. The outline can be loaded with separate loops that can fill in the gaps existing inside the model facial features. The method comes in handy when modeling a human face. In this way, it becomes more convenient around the eye sockets and fill-in them respectively to add more depth apart from creating it from a polygonal object. This feature allows building up a massive library of human components like lips, ears, eyes, etc.


Today, the gaming industry is constantly evolving into a more efficient and globally recognized marketing field, developers are constantly on the lookout for devising improved methods based upon game modeling needs. Developing breakthroughs in the modeling world requires a lot of time and money. If both of these resources are scarce then these aforementioned modeling techniques are all you need to create virtual and realistic gaming models. Conventional methods such as NURBS mesh, subdivision modeling, and procedural modeling are commonly employed by 3D modelers during game development processes for the enhanced user gaming experience.
