What is 3D Modeling & What’s It Used For?

3D modeling is a technique in computer graphics for producing a 3D digital representation of any object or surface.

An artist uses special software to manipulate points in virtual space(called vertices) to form a mesh: a collection of vertices that form an object. These 3D objects can be generated automatically or created manually by deforming the mesh, or otherwise manipulating vertices.

The 3D modeling process produces a digital object capable of being fully animated, making it an essential process for character animation and special effects. The core of a model is the mesh which is best described as a collection of points in space.

These points are mapped into a 3D grid and joined together as polygonal shapes, usually triangles or quads. Each point or vertex has its own position on the grid and by combining these points into shapes, the surface of an object is created.

Intro To 3D Modeling Software

There’s no shortage of 3D modeling programs to choose from.

Whether you’re looking to make animated characters, game models, or design a house, there’s a program out there to fit any budget.

Maya by Autodesk is the industry standard in 3D modeling and animation.
If you were to take a 3D modelling course at a university this is probably the software you’d use. Most professional studios look for experience with Maya when hiring new talent, so any artist looking to break into the industry should seriously consider learning Maya.
How to Use?

Cinema4D is another very popular choice.
The learning curve isn’t as steep as with Maya and it supports a more streamlined integration with tools like Adobe After Effects, making it an excellent choice for those interested in motion graphics.

Blender is a free and open-source 3D modeling and animation program.
It comes with a robust toolset capable of producing professional-quality assets and animations. No price tag. Blender’s learning curve is quite steep, however, and the software is considered non-standard in the industry.
How to Use?

SketchUp is a tool popular among architects and landscape designers.
It boasts an easy-to-use interface that makes it perfect for beginners looking to get started with 3D modeling for architectural work.

AutoCAD is the original CAD software used by millions around the world. It can be used to create precise 2D and 3D drawings and models, as well as electrical diagrams, construction drawings, and more.
How to Use?

But there are tons of other modeling programs out there so have a look in Google if you’re curious to find more.
