Becoming a 3D modeler not only requires skill but precise knowledge of certain tips, techniques, methods and features. Some of the important different techniques for creating 3D model are below mentioned.
This section covers the fundamentals of 3D modeling, which would help you to understand the entire workflow.
Primitive 3D modeling
Just because modeling evolved from the primitive shapes it is hard to leave them behind. Cones, cubes and cylinders are some of the primitives used for availing custom 3D modeling services. They are helpful to design furniture, building models and immovable objects which does not require any skeleton. 3DS Max and Maya are two of the best 3D design software used in the industry for developing such forms.
Polygons 3D modeling
Triangles, hexagons and other shapes are referred to as polygons. They are extensively used to create video game characters and other complex forms. Realistic appearance is the best feature of the output obtained while using polygon 3D modeling techniques. As the polygon count goes up, the image smoothness and crispness also rises. But it also becomes hard to render making it an always dropped choice by video game designers.
Procedural 3D modeling
This is another 3D modeling technique, which may come in different sizes or shapes. However, it can be broadly classified into two types. The first is based on the tool while the second is based on shading.
For the first one, different models will require different tools. You will also need to input a few parameters and run the program to create the models. In the second type, you can use the displacement output from the shader and create a complex surface or object.
This technique uses a kit of objects to create a detailed new object or to add details to an object that is already modeled. The technique is often used to add details to a hard surface object. Apart from that, it can be also used to add details to a scene.
However, while using this technique, make sure that you keep the frequency detail in mind. Ensure that there is a good mix of the distribution details.
NURBS 3D modeling
Non uniform rational B-spline technique refers to the use of smooth curves and surfaces while designing. A NURBS space can be crafted using two or more similar curves that are placed symmetrically. These 3D modeling techniques heavily depend on NURBS due to their flexibility. They are complex and require more time. But it allows better data transfer and easier to edit when using NURBS. They are very important and frequently accessed by professionals who provide 3D modeling services.
Boolean 3D modeling
In this technique, you use a model and add objects to it for creating a new shape. It is closely related to the box modeling technique and is often employed together. The combining of new shapes is usually carried out with boolean operations, hence, the name.
The different operations used are union, intersect, and difference. The union is used to combine objects, intersect to save the geometry of both objects, and difference to cut away a shape from an object.
Surface 3D modeling
Creation of organic mold depends heavily on using this technique. This feature helps to create a 3D spline using a 2D one. Skilled developers can create a spline within no time using surface modeling. The ones that we see in movies use surface modeling to an extent. This nifty little feature is available in almost all the top software’s. However, it is important to know the features of easy 3d modeling software for beginners.
Sub-division / Box 3D modeling
This can be categorized into a mix of NURBS and Polygonal modeling. It involves the process of creating a 3 Dimensional mold from a polygon and then converting it. Even though few techniques are involved in creating a sub-division form, it requires extreme care and refinement. The more you subdivide, the smoother it becomes. Due to this reason software’s include an option in their hot key feature to subdivide just to make the process a bit simpler.
This technique uses a camera and photographs of the object. Here, an object is photographed multiple times from different angles in good lighting conditions. It is then fed into the program to create a 3D representation of the object.
The representations generated here are very close to realism. Besides, the technique may also result in UV maps and textures sometimes. So, you do not even have to spend extra time creating them.
Similar to polygon and box modeling, digital sculpting also employs edges, vertices, and faces. The technique is mainly employed for creating animal or character designs.
Here, instead of selection, you can manipulate the models using brushes. The brush usually has an influence area that enables you to shape the geometry depending on your setting and brush type.
Having basic knowledge about the use of geometrical shapes will help amateurs to an extent in assuring best quality character 3D modeling services. Advanced forms require proper lighting, rendering, fur and many other characteristics.
