As 3D technology becomes affordable, it is increasingly being adopted in vast areas ranging from manufacturing to animation and rendering. The number of freelance 3D designers in Dubai is increasing as more graphic designers transition to 3D modeling to help meet the skyrocketing demand. Therefore, it is always necessary to ensure that your designer has a good grasp of 3D modeling. Your choice should demonstrate the essential qualities of successful 3D designers, including creativity, attention to detail, and problem-solving skills. 3D modeling is diverse, requiring the use of different skills and tools. This article covers the 3D modeling techniques that stand out as the popular types of 3D modeling.
6 Types of 3D Modeling and their Purposes
1. Box modeling
With this technique, the starting point is usually the primitive object, like a sphere or a cube. You work with low poly shapes to create an object. The technique is highly mechanical as you have to control individual faces, vertices, and edges to create your object. The main focus is on manipulating larger portions and whole shapes of an object at a time. You will most of the time, work with four sides called quads. Most of the standard 3D modeling tools can work with quads. This type of modeling works best with hard-surface objects like architectural visualization.
2. Polygon modeling
Polygon technique is similar to box modeling; it starts with a simple shape or a single vertex and works piece by piece. The emphasis on this technique is to work on the vertices and edges in a detailing way. This type of 3D modeling is perfect for hard surface objects that have more organic shapes. This technique uses quads to create objects, and hence, it uses the same tools with box modeling only with a big emphasis on creating natural characteristics. Subdivision can help in smoothing the geometry of objects.
3. Nurbs modeling
‘Non-uniform rational B-spline’ (Nurbs) is a different modeling technique to box and polygon types. It involves the creation of curved surfaces that you can manage with control points. Designers will opt for Nurbs modeling when they need to design very smooth curved surfaces. With this technique, it is possible to interpret between points of the same curve as well as develop bridges between several curves. This type of 3D modeling is common in engineering. Since this technique works with curves instead of edges, faces, or vertices, you will need different tools. The right tools should help you create a new curve, open and close curves, and move control points.
Most of the realistic 3D images that you see on the internet are created with this technique. Photogrammetry requires the camera to capture an object several times from all angles in an even lighting condition. The photos are then entered into a program that processes them and generates a 3D object. This method is unique and more realistic as it uses real data to create an object. Furthermore, the UV maps and textures are generated in the process, ensuring that you do not have to spend a lot of time making the object look real. The major downside of this technique is the extensive cleanup needed to get rid of other items captured by the camera. The method can only create an object that is physically present, as it must be captured first. This technique is relatively new, but it has become popular due to the easiness of creating 3D images. It can work with a host of technologies such as drones and scanners to recreate large structures and expansive areas.
5. Digital 3D Sculpting
This technique focuses more on the artistic side. It uses faces, vertices, and edges to create 3D objects, but the process is different from that of polygon and box modeling. Digital 3D sculpting uses brushes to manipulate shapes, eliminating the need to worry about the technical aspects of dealing with individual elements. The brush can organically reshape the geometry depending on the type of brush and settings. This 3D modeling is popular with animal, character, or creature design. It can also sculpt details that are difficult to create with polygon and box modeling.
You can use one of the several simulations, including physics, soft body, cloth, ocean, fluid, particles, fire, and smoke in your project. Accurate simulation depends on the project, but the majority have multipurpose uses. When creating a simulation, you will have to create different objects and parameters that interact differently within a setup. Simulation makes it easy to create certain situations like water splashing on a rock or a car accident. The technique focuses more on VFX than instant NURBS. It is a unique type of 3D modeling that works by tweaking and fine-tuning parameters to create or deform objects as opposed to directly focusing on the shape.
Before choosing the best type of 3D modeling for your project, you must consult a skilled freelance 3D designer in Dubai. The designer can propose a technique that can help you achieve the same results quicker and with less effort. A good designer can use multiple 3D modeling techniques to create advanced projects.
