How to Make a 3D Model with Traditional Modeling
What is Traditional 3D Modeling?
Traditional 3D modeling is the process of creating a 3D object by manipulating polygons. It's like digital sculpting: you start with a basic shape and then push, pull, and extrude its vertices, edges, and faces to create the form you want. There are a few different approaches within traditional 3D modeling:
- Polygonal Modeling: This is the most common method, where you directly edit the polygons of the mesh. It's a versatile technique that can be used to create anything from low-poly game assets to high-resolution characters.
- NURBS Modeling: NURBS (Non-Uniform Rational B-Splines) are mathematical representations of curves and surfaces. This method is great for creating smooth, organic shapes and is often used in industrial design and for creating models that need to be very precise.
- Digital Sculpting: This is a more intuitive and artistic approach to 3D modeling. Instead of manipulating individual polygons, you use digital brushes to sculpt your model, much like you would with clay. This is a popular technique for creating detailed characters and creatures.
Popular 3D Modeling Software
There are a ton of 3D modeling software options out there, but here are a few of the most popular:
- Blender: This is a free and open-source 3D creation suite that has become incredibly popular in recent years. It's a powerful tool that can be used for everything from modeling and sculpting to animation and visual effects.
- Autodesk Maya: Maya is an industry-standard 3D animation software that is used in many professional film, television, and game development studios.
- Autodesk 3ds Max: 3ds Max is another popular choice for 3D modeling, animation, and rendering, especially in the architectural and product visualization industries.

How to Make a 3D Model with Kitbashing
Kitbashing and using 3D marketplaces are all about using existing assets to create something new. This is a popular technique in the film and game industries for creating complex scenes and objects quickly.
What is Kitbashing?
Kitbashing is the process of taking parts from different 3D models and combining them to create a new model. For example, you could take the wings from a plane model, the body from a tank model, and the legs from a robot model to create a unique sci-fi vehicle. It's a fun and creative way to make new models without having to start from scratch.
Where to Find 3D Models
There are a number of online marketplaces where you can find 3D models to use in your projects. Some of the most popular include:

| Great for quickly populating scenes and creating prototypes | You need to be mindful of licensing and usage rights |
How to Make a 3D Model with Procedural Generation
Procedural generation is the process of using algorithms to create 3D models. Instead of manually creating every detail, you write a set of rules that the computer follows to generate the model. This technique can be used to create everything from vast landscapes to intricate objects.
What is Procedural Generation?
Procedural generation works by defining a set of rules or a procedure that generates the model. For example, you could write a script that generates a tree by starting with a trunk, then branching out into smaller and smaller branches, and finally adding leaves. By changing the parameters of the script, you can generate an infinite variety of trees.
Tools for Procedural Generation
- Houdini: This is a professional 3D animation and visual effects software that is known for its powerful procedural modeling tools.
- Blender's Geometry Nodes: Blender has a powerful node-based system called Geometry Nodes that allows you to create complex procedural models without writing any code.
