How to Train Generative AI for 3d models


The generative design market will grow at an annual rate of 20% by 2030, which means that the market will take a huge jump from USD 1.88 billion to USD 9.04 billion by the end of the forecast period. With recent advancements in AI, especially generative adversarial networks (GANs), the process of 3D modelling generative AI has become increasingly important for creating the highly realistic assets that drive innovation in this rapidly expanding market. Neural radiance fields that use deep neural networks to encode 3D geometry and appearance as continuous functions play a key role by allowing novel views to be rendered from any angle.

Benefits of Generative AI in 3D Modelling 

Integrating generative AI into 3D modelling tools has the potential to boost creativity, productivity, and accessibility in design across various industries. Some major benefits of AI in 3D modelling include:

Creativity and Design 

Traditional modelling requires much time and skill to create complex designs, but AI algorithms can generate intricate and innovative 3D models with minimal input. This capability allows designers and artists to explore a wider array of design possibilities without the constraints of time or technical expertise. For instance, an architect could use generative AI to explore various structural forms, textures, and materials, quickly iterating through design options that would be time-consuming to model manually. This not only boosts creativity but also leads to more diverse and innovative design outcomes. Machine learning can learn from existing design styles and propose new combinations.

Streamlined Workflow 

In traditional 3D modelling, tasks like sculpting intricate details or creating realistic textures can be labour-intensive and time-consuming. However, AI algorithms can automate these processes, generating detailed models and textures with precision and speed. This automation frees up designers to focus on the more creative aspects of their work, such as conceptualisation and fine-tuning designs. For industries like animation and game development, this means quicker turnaround times for creating detailed characters and environments. AI can assist in optimising models for different use cases, such as reducing polygon count for real-time rendering or ensuring models are structurally sound for physical manufacturing.

Personalisation and User Engagement

By leveraging user data and preferences, AI algorithms can create customised 3D models tailored to individual needs and tastes. This has profound implications for industries like retail, where consumers can have products designed to their specifications, from customised jewellery to bespoke furniture designs. In the entertainment industry, AI-driven personalisation can create unique gaming experiences, with environments and characters that adapt to a player's style or preferences. This level of personalisation not only improves user experience but also fosters a deeper connection between consumers and products or brands. 

Accessibility for All

Generative AI democratises 3D modelling, making it accessible to a broader range of users regardless of their technical expertise. Traditional 3D modelling requires specialised skills and knowledge, often posing a barrier to entry for hobbyists, small businesses, and educational institutions. However, AI-driven tools can simplify the modelling process, allowing users with minimal training to create complex models. This democratisation is particularly impactful in education, where students can engage with 3D design without the steep learning curve. It also empowers small businesses to create high-quality 3D content for marketing or product development, which was previously only feasible for larger companies with more resources. 

Cost Reduction and Resource Optimisation

Implementing generative AI in 3D modelling can lead to significant cost reductions and resource optimisation. The efficiency and speed provided by AI not only reduce the time required to create models but also minimise the need for extensive human resources. This is particularly beneficial for industries where 3D modelling is a major part of the production process, such as film, gaming, and product design. Smaller teams can produce high-quality work in less time, leading to lower labour costs and enabling more projects to be undertaken. AI can optimise models for resource-efficient production, whether that's in digital rendering or physical manufacturing. For instance, AI algorithms can suggest design modifications that use less material while maintaining structural integrity, leading to cost savings and environmental benefits.

How to Train Generative Models for 3D Design

Training generative AI for 3D modelling involves a complex and meticulous process, requiring careful consideration of datasets, model architecture, and machine learning methodologies. To give you an idea, here’s a quick overview of the practical steps involved in this process:

Step 1: Selecting and Preparing Datasets

The first and most important step in training generative models for 3D design is the selection and preparation of datasets. High-quality datasets are essential for training a model that can generate detailed and accurate 3D models.

  • Data Collection: Gather a diverse set of 3D models from various sources. These can include public datasets like ShapeNet, ModelNet, or proprietary datasets if available. The models should cover a wide range of categories and complexities to ensure the trained model can handle various design scenarios.

  • Data Pre-processing: Standardise the data format (e.g., STL, OBJ) and normalise the scale and orientation of the models. This standardisation ensures consistency in training.

  • Data Augmentation: Augment the dataset to include variations of the original models, such as different textures, colours, or distorted shapes. This increases the robustness of the model.

Step 2: Choosing a Model Architecture

Selecting an appropriate model architecture is pivotal. Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs) are commonly used for 3D generative tasks.

  • GANs: Useful for generating high-quality, realistic models. They consist of a generator and a discriminator, working in tandem to improve the quality of generated outputs.

  • VAEs: Efficient for creating variations of 3D models and are better at handling complex distributions.

Step 3: Model Training

With the dataset prepared and model architecture chosen, the next step is to train the model.

  • Loss Function and Optimisation: Define appropriate loss functions and optimisation algorithms. For GANs, this involves optimising both the generator and discriminator.

  • Regularisation and Batch Processing: Implement regularisation techniques to prevent overfitting. Utilise batch processing for efficient training.

  • Monitoring and Evaluation: Continuously monitor the training process using metrics such as the Fréchet Inception Distance (FID) for GANs, and adjust parametres as necessary.

Step 4: Fine-tuning the Model

After the initial training, fine-tuning the model for specific 3D design tasks is important.

  • Task-specific Training: If the model is to be used for specific types of 3D design (like architectural models or organic shapes), it may be beneficial to fine-tune the model with datasets focused on these areas.

  • Hyperparametre Tuning: Experiment with different hyperparametres to find the best combination for the desired output quality and efficiency.

  • Transfer Learning: Use pre-trained models on related tasks and fine-tune them with your specific dataset to save time and computational resources.

Step 5: Inferencing, Post-Processing and Evaluation

Once the model is trained and fine-tuned, the next step is to perform inferencing to generate designs, followed by post-processing and evaluation.

  • Inferencing: To use the trained models for generating 3D designs, you need to perform inferencing. Inferencing is the process of running the trained model on new input data to obtain the desired output. Inferencing typically requires computational resources such as GPUs to achieve reasonable throughput and latency.

  • Post-processing: The outputs generated during inferencing need to be converted into usable 3D software or printing format. This may involve cleaning up the generated data, applying additional transformations or translating the representations into industry-standard formats.

  • Evaluation: The next step is to assess the quality of generated designs through subjective evaluation (designer feedback) and objective metrics (geometrical accuracy, fidelity to input requirements). This is crucial to ensure that the generated designs meet the desired specifications and requirements.

Step 6: Iterative Improvement

Training generative 3d modelling is a repetitive process. After initial training, models often need further cycles, fine-tuning, or dataset modifications. This is guided by feedback and evaluations, ensuring continuous improvement and adaptation to specific requirements in 3D design contexts.

Limitations in Using Generative AI for 3D Models

Using Generative AI in 3D modelling offers significant advantages, such as automating aspects of the design process and providing creative inputs. However, there are several limitations you should consider:

  1. Quality and Detail: While Generative AI can produce basic 3D models, the intricacy and detail required for professional-grade work often exceed its current capabilities. These models may lack the precision necessary for technical fields like engineering or architecture, where exact specifications are critical.

  2. Lack of Creativity: AI algorithms generally operate by recognising patterns in data and replicating them. They lack the human designer's intuitive understanding of aesthetics, context, and functionality. This can lead to designs that are technically sound but lack the creative flair or practicality that a human designer would naturally incorporate.

  3. Data Dependency: The quality of a generative AI's output is heavily dependent on the quantity and quality of the data it has been trained on. If the training data is limited, biased, or of low quality, the AI will struggle to produce high-quality, diverse 3D models.

  4. Computational Resource: High-quality 3D modelling using AI requires significant computational resources, including advanced GPUs and substantial memory. This can make it inaccessible or prohibitively expensive for individuals or small organisations, limiting its use to those with substantial resources.

  5. Ethical Concerns: When generative AI is used to create 3D models, it raises questions about originality and copyright, especially if the AI's training data includes copyrighted or proprietary designs.
