3D modeling has always been one of the most complex and time-consuming parts of digital art and design. However, with major advancements in Artificial Intelligence (AI), the process has changed dramatically. AI now helps simplify, accelerate, and even enhance creativity, making 3D design more accessible than ever before.
In this guide, we’ll explore the main AI approaches used in 3D model generation and introduce some of the best tools you can try today.
Main AI Approaches in 3D Model Generation
1. Text-to-3D
Generate 3D models directly from a text description — for example: “a flying dragon with large wings and green scales”. This is powered by generative architectures like Diffusion Models, and makes 3D accessible even to non-specialists.
2. Image-to-3D
Reconstruct 3D objects or scenes from 2D images. AI analyzes light, shadow, texture, and depth to produce realistic models — a staple in AI-assisted photogrammetry.
3. Neural Radiance Fields (NeRFs)
NeRFs learn a radiance field from a series of 2D images, enabling high-detail rendering of new viewpoints without traditional mesh creation.
4. Generative Models (GANs & Diffusion Models)
These can produce entirely new and realistic 3D models from scratch, though often combined with user inputs (text or images) for more control.
