3D modeling in architecture enables the creation of an accurate digital depiction of a building design. There are various approaches to the modeling process, depending on the function of the 3D object.
In this article, you’ll discover the four primary CG modeling kinds that can be useful to you in various project phases.
Direct Modeling
In the case of direct modeling, you manipulate various simpler shapes to combine them into a complex 3D entity. The model’s general shape won’t change if you change one of them or add a new one.
When you need CG objects to produce photorealistic photographs, this kind of 3D modeling excels. For instance, you could add them to your portfolio, post on social media, or enter them in architectural design contests. You may even use them to show clients during presentations. Using this technique, you can also swiftly test different design ideas and brainstorm new ones. All because it enables you to freely modify 3D things without being constrained by predefined parameters.
3ds Max, Blender, and Maya are the most used programs for creating 3D models in this manner.
Polygonal and Spline modeling are currently the two primary categories of direct modeling.
Polygonal Modeling
The most adaptable method for making 3D models is this one. Here, a mesh of tiny “building blocks” with three or more straight sides called polygons is shaped to create an item. The number of polygons determines how detailed the model is; the more polygons, the more detailed the model.
Spline Modeling
Splines, which are 2D shapes like lines and circles, are used in this type of modeling to produce 3D things with intricate shapes. Spline modeling enables you to deal with tools like Bezier curves, and is frequently used to construct 3D models containing many curves swiftly. Rotating the 2D shape of your item using the Lathe modifier will help you create a 3D object.
Parametric Modeling
The parametric modeling method is far more mathematical than direct modeling. Here, you add sets of parameters to your models to construct and change them. They establish the characteristics of each component of the model as well as the connections between them. When you add new parameters, all objects are automatically created and changed. As a result, any modification you make impacts the overall design. In this manner, you may quickly determine whether your ideas are feasible.
Building Information Modeling
Building information modeling, or BIM, is the top technology for visualizing architecture for construction and project management. It enables you to build an intelligent model that contains structured data about each component. By doing so, you may precisely calculate the quantity of each material required, the time required to finish each stage of construction, and the project’s final cost.
Point Cloud Modeling
In this instance, 3D scanning is used to produce a point cloud, which is a 3D depiction of an existing building. The point cloud can then be imported into a digital environment using a program like Autodesk ReCap Pro so that it can be edited, measured, turned into a 3D mesh, or used to create a BIM model.
