Demystifying 3D Models: How to make a 3D model

In this blog post, we will explore the fundamentals of 3D modeling and introduce you to a powerful tool called Sloyd.ai that can help generate 3D assets quickly and easily.

3D models have become an indispensable part of various industries, from architecture to gaming and manufacturing. But what is a 3D model, how are they made, and what are they made of? This article aims to shed light on the concept of 3D models and these topics.

What are 3D Models?

3D models are virtual representations of objects or scenes, used in a wide range of industries. 3D models provide depth and perspective, allowing users to view an object from different angles and even manipulate it in a virtual environment.

There are two main concepts of a 3D model:

  1. Meshes: A mesh is a collection of interconnected vertices, edges, and faces that form the structure of a 3D object. Learning how to manipulate and modify meshes will be the foundation of your 3D modeling skills.
  2. Texturing and Materials: Applying textures and materials to your 3D models brings them to life. Experiment with different materials, such as metals, plastics, and fabrics, to achieve the desired visual effect.

The Process of Creating 3D Models

Creating a 3D model traditionally involves several steps, each requiring technical expertise and artistic skills.

1. Conceptualization

The first step in crafting a 3D model is typically conceptualization. Artists, designers, or engineers determine the purpose and appearance of the model. This involves defining its purpose, function, and intended use. They collect reference materials and sketch the initial design.

2. Modeling

Once the concept is finalized, the actual modeling process begins. Using 3D modeling software, the artists build the object's digital structure, defining its shape, size, and intricate details.

Traditionally, this a time-consuming and difficult task which has been done manually, but with automation tools like Sloyd, 3D modeling has become much more accessible.

3. Texturing

After the 3D model's structure is complete, textures are added to the surface to give it a realistic appearance. Texturing involves applying images or patterns to the model, making it look more authentic and visually appealing.

4. Lighting and Shading

Once the model is textured, it's time to add lighting and shading effects. Lighting sets the ambiance and mood of the scene, while shading creates depth and realism. This interplay of light and shadow brings the 3D model to life, making it appear as if it exists in a tangible space.

5. Rigging and Animation

For models intended for animation or dynamic use, rigging comes into play. Rigging involves creating a digital skeleton or framework for the model, enabling it to move and bend realistically. With the rig in place, animators can breathe life into the model, making it walk, talk, and perform various actions.

6. Rendering

Rendering is the process of converting the 3D model into a 2D image or animation, like capturing a photograph of the 3D model in its virtual environment. It involves adding lighting, shadows, and composition with other 3D models to achieve a lifelike representation.

Anatomy of a 3D Model: Faces, Vertices, and Edges

A 3D model is a complex structure composed of several fundamental elements that define its shape, appearance, and geometry.


Vertices (single form: vertex) are the fundamental building blocks of a 3D model. They are points in 3D space where three or more edges meet. Think of vertices as the corner points of a geometric shape.

Vertices define the shape and structure of the model, and the number of vertices directly affects the level of detail and complexity.


Edges are the lines that connect two vertices in a 3D model. They form the boundaries between different faces, defining the outlines and contours of the object.

While edges are crucial for defining the geometry, they do not have any width or volume themselves; they are purely mathematical constructs connecting vertices.


Faces are the surfaces that enclose a specific area of a 3D model. They are formed by connecting a series of edges in a closed loop. Faces give the model its visible form and appearance.

Together, these elements create the structure of the 3D model and enable it to have depth and volume, making it more than just a flat 2D representation.

Choosing the Right 3D Modeling Software

There are many 3D modeling tools out there, and quite fairly, most are quite complex. Some popular choices include:

  1. Blender: A free and open-source software, Blender offers a robust set of features for most use cases and an active community, however it does take some time to learn and master.  
  1. Autodesk Maya: Widely used in the entertainment industry, Maya provides advanced tools for modeling, animation, and rendering. It offers a free trial for newcomers, but as a professional tool it comes with a premium price.
  2. SketchUp: Known for its user-friendly interface, SketchUp is an excellent choice for architectural and product design. It offers a free version with limited features and a paid Pro version.

Exploring AI tools for Quick and Easy 3D Asset Generation:

Sloyd.ai is an innovative tool that utilizes procedural generation and artificial intelligence to generate 3D assets quickly and easily. Whether you're a beginner looking to kickstart your 3D modeling journey or a seasoned artist in need of a time-saving solution, Sloyd can be a game-changer.

Here's how you can use it:

  1. Sign up and access the Sloyd.ai platform. It offers a user-friendly interface with a library of generators to create 3D models.
  2. Browse through the available categories or search for specific objects you need for your project.
  3. Select a generator and customize it according to your preferences. Sloyd allows you to tweak various parameters like shape, size, texture, and complexity.
  4. Once you're satisfied with the adjustments, download the generated 3D model in a compatible file format for further editing or direct use in your projects.

Enhancing Your Skills and Practice

While tools like Sloyd can really accelerate your workflow, if you want to create 3D manually you need consistent practice and learning. Here are a few tips to help you improve:

  1. Tutorials and Online Resources: Utilize online tutorials, courses, and forums to learn new techniques and get inspiration from other artists in the field.
  2. Analyze Real-World Objects: Study real-world objects and attempt to recreate them in 3D. This practice will sharpen your observation skills, enable you to understand the nuances of different objects, and refine your modeling abilities.
  3. Experiment and Push Yourself: Embrace experimentation and push the boundaries of your creativity. Explore different techniques, styles, and unconventional approaches to challenge yourself and uncover new possibilities within 3D modeling.

Final Thoughts

While the process of manually creating 3D models used to be a time-consuming and labor-intensive task, 3D automation tools like Sloyd have changed this story. These tools makes 3D modeling more accessible and efficient than ever before. Now, even those without extensive technical expertise can harness the power of automation to create stunning 3D models with ease.

Still, it can be valuable to combine the power of automation with a solid grasp of fundamental 3D techniques. These foundational skills not only enhance the efficiency of working with automation but also provide a deeper understanding of the underlying principles of 3D modeling. The future of 3D modeling is undoubtedly bright, with automation paving the way for greater creativity and productivity in the digital realm.
