3-D modeling refers to a technique in computer graphics used to develop a 3-D animation of various objects or surfaces. It is widely used in video games, movies, architecture, interior design, and even medicine. Whether you are new or familiar to 3-D designing, these 3-D modeling techniques can definitely improve your artwork and animations like you have collaborated with some of the best 3-D game art outsourcing companies.
1. Box Modeling
3-D box modeling technique uses 3-D design software with primitive shapes, including a box, cylinder, and more, where artists can sculpt their final model.
Lay down the specific details about what you want and how you want to accomplish your model. You can add more elements later. Then you can start with your rough drafting. Rough drafting is the process of making desired segments, iterations, and elements until you arrive at a workable outline or shape silhouette.
To come up with more desirable results, finalizing your details is important. Here, you can fill the gaps in your model or round off the edges. Any unnecessary detail or orientation can be corrected in the finalizing stage.
Last is the cleaning-up stage. This is where you smooth out your artwork through repeated commands. You can add fabric folds or work your model silhouette from across all directions to improve the geometric flow and achieve sharper edges.
2. Contour/Edge Modeling
This is another type of polygonal modeling technique. But instead of enhancing shapes, it helps creates models piece by piece. This is an ideal technique for certain meshes that are difficult to accomplish through box modeling. You only need to place the loops in the polygon along the outline and fill the gaps that lie between them to develop a model.
3. Spline Modeling
Also known as NURBS modeling, spline modeling is the oldest technique. It was launched the same time 3-D modeler software was introduced. NURBS stands for “non-uniform rational basis splines.”
Of all the 3-D modeling techniques, spline modeling is potentially capable of creating high-quality and accurate models. It consists of almost all types of digital patterns and shapes such as 2-D forms, circles, arcs, and other complex structures and surfaces. This can make the model suitable for complex animation, detailed orientation, and 3-D game assets.
But spline/NURBS modeling contains a number of control points, making it difficult to use. But there are many 3-D modeling software that can help you simplify the method to optimize its use.
4. Subdivision Modeling
This uses a mix of polygonal and NURBS modeling techniques to create a model. Once developed inside a polygon, the model is then converted into a subdivision. The greater the subdivisions, the clearer and smoother the results are. When done, the artist can easily transfer the model to different software.
5. Digital Sculpting
This has innovated the art of sculpting from rocks and woods to computer screens using specialized software. Here, you form a model using a palette of different textures and shapes similar to real-life clay and rocky compositions. Multiple brushes and other specialized tools are used to refine and polish the model.
The completed project may be done in a matter of minutes or may take a significant amount of time, depending on the complexity of the model. In case you’re wondering, the real-life clay appearance is made possible using intricate polygon meshes created using mathematical calculations.
6. Procedural Modeling
This uses a set of rules and algorithms to create a model. That includes L-systems and fractal modeling generative. This is used for developing large-sized 3-D models that other techniques may not be able to accommodate. The outcome known as procedural content can be embedded within films and gaming engines and displayed on the Internet. User inputs are not required to edit the model, but manual edits are also made possible.
7. Image-based Modeling
Derived from 2-D sets that are constant and static in nature, imaged-based modeling is used for projects with a specific budget, time restrictions, and low probability to fully develop 3-D images. Using two-dimensional images, you can create three-dimensional models. It’s widely used in virtual reality and the entertainment industry.
8. Surface Modeling
This allows you to scan a solid surface CAD object from the desired angle using a complex mathematical method. The objects used for surface modeling are usually complex, making it the most suitable technique for architectural rendering. The object to be displayed is converted into 3-D versions for smooth transitions.
Creating crisp and high-quality models can be a challenge. But by learning the different 3-D modeling techniques, you can definitely create a masterpiece.
