How to create 3D models from 2D images

Create 3D models from 2D images It is a fascinating technology that increasingly has more applications in different sectors (video games, Print 3D, animation, architecture…). Thanks to the advances in Artificial Intelligence y specialized software, the wonder of transforming a flat image into a three-dimensional model is easier than ever. You don't even need to have advanced knowledge of 3D modeling.

In this article, we will explore in detail how to convert 2D images into 3D models using different tools and methods. Also, we will discuss the and advantages and disadvantages of each option so you can choose the one that best suits your needs.

Why convert 2D images into 3D models?

Creating a three-dimensional model from an image has multiple applications in different fields. From graphic design to 3D printing, cinema and architecture, this conversion allows you to take illustrations or photographs to a whole new level.

Estos son los de algunos most common uses of this fabulous technology:

• 3d print: It allows designs to be materialized from sketches or illustrations.
• Animation and video games: Facilitates the creation of models for digital worlds.
• Architecture and engineering: To convert plans into interactive models.
• Marketing and branding: Creation of three-dimensional objects for advertising.

These are just a few examples that are already being worked on today, but the technology for creating 3D models is constantly evolving, so it is to be expected that in the not-too-distant future we will be able to see new and amazing applications in many more areas.

Methods for converting 2D images into 3D models

But how is this transformation performed? There are various tools and methods for transforming flat images into three-dimensional models, from photogrammetry software to solutions based on artificial intelligence. Below are the most notable options:

1. Using Photogrammetry with Meshroom

Meshroom is a free and open source software that uses photogrammetry to generate or create 3D models from photographs. This method consists of capturing multiple images of an object from different angles., allowing the software to create a volumetric model with depth and detail.

Advantages:

• Free and accessible software.
• Allows obtaining highly detailed models.

Disadvantages:

• It requires good quality photographs and in large quantities.
• The model generation process can be slow.

2. AI-based conversion with tools like Dreamina

Artificial intelligence-based tools have revolutionized the conversion of images into 3D models. Platforms such as Dreamina (as an example, the image above) allow you to transform images with just a few clicks, using advanced algorithms to create 3D models, that is, three-dimensional, based on the depth and contours of the original image.

Advantages:

• Automated and fast process.
• No advanced modeling knowledge required.

Disadvantages:

• Models may require additional software editing.
• It relies on cloud servers, which may limit its use.

3. Using 3D modeling software like Blender

Blender is one of the most powerful tools currently available for creating 3D models. While it does not have an automatic conversion function, it allows us to generate three-dimensional models from 2D images using layout techniques and extrusionIn other words, it allows us to create objects with fixed cross-sectional profiles by pushing certain types of materials.

Advantages:

• High customization and modeling control.
• Completely free and open source.

Disadvantages:

• Requires advanced 3D modeling knowledge.
• Manual process that may be slower.

The possibility of mastering the technique of creating 3D models by transforming 2D images open new opportunities in various sectors. From digital art to industrial production, this technology makes it possible to create models accurately and quickly without the need for advanced three-dimensional design skills.
