A Quick Guide To 3D Mesh Modeling

Technology has come a long way in modeling. Even using paper and pen is a rare practice nowadays. But other than how neat it is compared to the rest, digital modeling—particularly three-dimensional (3D) modeling—allows users to put different methods into practice. 

However, regardless of their differences, 3D modeling has similar goals: to simulate everything to be as realistic as possible. Using only calculations and necessary tools, what used to be a blank screen can now present a fully modeled terrain inspired by real-life sceneries. 

From animated movies to video games, knowing how to create 3D models has played a significant role in entertainment. Naturally, that’s not the only area it excelled in since car models and new technological blueprints are also presented as 3D models.

Nevertheless, the longer you’re exposed to 3D modeling, the more familiar you might get with its types, namely mesh modeling.

What Is Mesh Modelling?

Since it’s under 3D modeling, mesh modeling, or polygonal modeling, takes shape as a multi-dimensional figure. However, mesh models aren’t given that much spotlight due to how basic their details are. 

On the other hand, solid modeling is given greater attention because it’s better suited for test runs. As for surface models, although they resemble mesh models the most, they appear more fluid. 

Meanwhile, you can convert a mesh model into a solid or surface model. Considering the ‘mesh’ only works as the 3D model’s outline, 3D artists can easily manipulate it to assume different forms. Thus, making them appear as blank linework for you to fill in with color later.

Parts Of A 3D Mesh

Since they consist of three dimensions, you’re bound to see 3D mesh feature components completely different from basic 2D shapes. And right off the bat, software such as Spatial’s 3D Mesh and others can easily use character models to recreate expressive facial characteristics. On the other hand, three-sided models are found to excel better in gaming models.

Essentially, mesh models are made up of three key elements:

  • Faces
  • Edges
  • Vertices

In modeling mesh, you only notice how detailed your model is once you’ve realized how low your polycount is. And if you haven’t already guessed, polycount is directly related to the 3D model’s faces because it indicates how many polycounts the figure has accumulated. 

In other words, the lower the polycount is, the vaguer their details are. As for edges, these are simply points connected to form a figure. Meanwhile, vertices (or points) encourage mobility for the user to manipulate its shape.

How To Create Mesh Models

Since you’ve already got the gist of what goes on, why not try your luck at creating a mesh model designed after your favorite thing?

1. Start With The Base

Before you start your calculations, you must be mindful of what parts are connected. Otherwise, your model might turn out deformed. Therefore, instead of quickly diving into creating your own mold, you must first get started with the mold itself. 

It’s important to take your time, ensuring it keeps its shape. Significantly, you should never smooth a mesh model as soon as you create it. Otherwise, you’re hindering the model from performing decently. 

After all, the higher the polycount, the more likely it is to affect its performance. This also adds complexity, which can slow it down. You can start adding details when you’re completely done molding the mesh.

2. Focus On One Face At A Time

Your mesh turning out completely smooth should be the last thing you’re gunning for. Because, besides making it more complicated as it is, you can easily ruin your progress by making one wrong move. 

Hence, take the time to refine each face of the mesh. Or if you’re not too keen to refine the mesh model’s every component, you can simply refine the individual faces that need more attention in detailed modeling.

3. Use Gizmos

There can never be an artist without their medium and tools. The same applies to 3D model artists. Despite having it in a virtual setting, 3D models are challenging to modify. Therefore, you’ll need tools or gizmos designed to fulfill specific commands and apply them to the model, such as moving, rotating, or giving it scale.

4. Look At Different Angles

Since 3D mesh models are multi-dimensional, it only makes sense to look at your creations from every angle to fully appreciate them. But besides appreciation, you should take this opportunity to check if there are any abnormalities on the model’s faces. This way, refining it won’t cause too much trouble.

Takeaway

Art has always found its way in the most unlikely places. However, just like any art process, it takes a long time to find the suitable method for you, and even longer to perfect it. Nevertheless, the best place to start your 3D modeling is by looking into mesh modeling.
