3D modeling is just about everywhere in the modern world, even if it isn’t obvious. The devices and appliances we use are often created and refined using specialized software. Many of the objects in modern TV ads, shows, and movies are also digital creations – even if they can’t easily be distinguished as such.
If you’re looking to get into 3d modeling, then the good news is that there’s an unprecedented array of tools, instruction, and number-crunching hardware at your disposal. So, how do you get started?
Understanding the Basics of 3D Modelling
First, it’s worth drawing a distinction between polygonal modeling, where every model is made of a series of interconnected points called vertices, and ‘NURBS’ (that’s non-uniform rational b-spline) modeling, which uses complex math to generate infinitely smooth shapes.
The former is best for creating assets for video games and films; the latter is used for creating designs that will ultimately find their way into the real world.
Choosing the Right 3D Modelling Software
If you’re looking to create polygonal models, then Blender is the obvious choice. It’s free, hugely feature-rich, and supported by a vast community of online creators and instructors.
If you’re looking to get into Computer Aided Design, on the other hand, you might consider free 3D design software like Designspark Mechanical and Tinkercad. One thing that might be worth noting is the use of Building Information Modelling, which has become a standard in the construction industry. Aspiring architects will wait to acquaint themselves with this standard.
Creating Complex Geometry
Creating a 3d object requires considerable practice. In Blender, you might begin with a simple object (called a ‘primitive’), and make it gradually more complex with the help of tools like extrude, grab, scale, and the knife. You might also enter into specialized workspaces, like Sculpt, which will help you to generate geometry using a graphics tablet and a stylus.
Common Challenges and How to Overcome Them
Major challenges to beginners are often difficult to diagnose. They often involve overlapping geometry, non-uniform scaling, and flipped normals. Learning to recognize common faults, and correct them, is part of the challenge of building your skillset as a beginner in 3d modeling.
Leveraging Online Resources and Communities
One sure way to accelerate your learning experience as a newcomer to any piece of software is to seek out an online community via platforms like Reddit and Discord. That way, you’ll be able to ask questions, and get quick feedback on your work. You’ll also save yourself the stress of not knowing what’s causing a particular issue for you!
