Era3D
Era3D is a multi-view generation model developed by Alibaba that produces high-resolution, camera-aware multi-view images and normal maps from single input images for 3D reconstruction. The model introduces two key innovations that address common limitations in multi-view generation: a focal length estimation module that adapts to the camera perspective of the input image, and an efficient row-wise attention mechanism that enables generation at higher resolutions than competing methods while using less GPU memory. Era3D generates six consistent views along with corresponding normal maps at 512x512 resolution, providing rich geometric information for downstream 3D mesh reconstruction. The camera-aware design means the model can handle input images taken from different perspectives and focal lengths without degradation in output quality, a significant improvement over methods that assume a fixed camera model. The row-wise attention mechanism replaces the computationally expensive full cross-view attention with a more efficient alternative that processes attention along horizontal rows, reducing memory requirements while maintaining view consistency. Released in May 2024 under the Apache 2.0 license, Era3D is fully open source with code and pre-trained weights available on GitHub. The model demonstrates strong performance across diverse object categories and produces clean multi-view outputs suitable for high-quality 3D reconstruction. Era3D is particularly valuable for professional 3D content creation workflows where input images come from varied sources with different camera characteristics, and where high-resolution multi-view generation is essential for capturing fine details in the final 3D models.
InstantMesh
InstantMesh is a feed-forward 3D mesh generation model developed by Tencent that creates high-quality textured 3D meshes from single input images through a multi-view generation and sparse-view reconstruction pipeline. Released in April 2024 under the Apache 2.0 license, InstantMesh combines a multi-view diffusion model with a large reconstruction model to achieve both speed and quality in single-image 3D reconstruction. The pipeline first generates multiple consistent views of the input object using a fine-tuned multi-view diffusion model, then feeds these views into a transformer-based reconstruction network that predicts a triplane neural representation, which is finally converted to a textured mesh. This two-stage approach produces significantly higher quality results than single-stage methods while maintaining generation times of just a few seconds. InstantMesh supports both text-to-3D workflows when combined with an image generation model and direct image-to-3D conversion from photographs or artwork. The output meshes include detailed geometry and texture maps compatible with standard 3D software and game engines. The model handles a wide variety of object types including characters, vehicles, furniture, and organic shapes with good geometric fidelity. As an open-source project with code and weights available on GitHub and Hugging Face, InstantMesh has become a popular choice for developers building 3D asset generation pipelines. It is particularly useful for game development, e-commerce product visualization, and rapid prototyping scenarios where fast turnaround and reasonable quality are both important requirements.
One-2-3-45
One-2-3-45 is a single-image 3D reconstruction system developed by researchers at UC San Diego that generates textured 3D meshes from a single input image through a two-stage pipeline combining multi-view generation with sparse-view 3D reconstruction. The name reflects the core process: from one image, generate two to three to four to five views, then reconstruct a complete 3D object. In the first stage, a fine-tuned Zero123 model generates multiple novel views of the object from different angles based on the single input photograph. In the second stage, these generated multi-view images are fed into a cost-volume-based sparse-view reconstruction network that produces a textured 3D mesh with consistent geometry. Released in June 2023 under the MIT license, One-2-3-45 was among the first systems to demonstrate that combining 2D diffusion models with 3D reconstruction could produce reasonable 3D assets in under a minute. The model handles a variety of object types including everyday items, animals, vehicles, and artistic objects. Unlike optimization-based approaches like DreamFusion that require per-object optimization taking tens of minutes, One-2-3-45 runs in a feed-forward manner making it significantly faster. The output meshes include color and texture information and can be exported for use in standard 3D applications. As a fully open-source project with code available on GitHub, it has served as an influential reference for subsequent research in single-image 3D generation. The system is particularly useful for researchers and developers exploring rapid 3D content creation from limited input data.
OpenLRM
OpenLRM is an open-source implementation of the Large Reconstruction Model architecture for single-image 3D reconstruction, developed by Zexiang Xu and collaborators. The project provides a fully open and reproducible implementation of the LRM approach, which uses a transformer-based architecture to predict 3D representations from single input images in a feed-forward manner. OpenLRM processes an input image through a pre-trained vision encoder like DINOv2, then feeds the resulting features into a transformer decoder that generates a triplane-based neural radiance field representation, which can be rendered from novel viewpoints or converted to a textured 3D mesh. The entire reconstruction takes only a few seconds on a modern GPU, making it practical for interactive applications and batch processing workflows. Released under the Apache 2.0 license in December 2023, OpenLRM fills a critical gap in the 3D AI research community by providing an accessible reference implementation that researchers can study, modify, and build upon. The model supports various output formats and can be integrated into existing 3D pipelines for applications ranging from game development to e-commerce product visualization. OpenLRM handles diverse object categories including furniture, vehicles, characters, and everyday items with reasonable geometric fidelity. Pre-trained model weights are available on Hugging Face for immediate use. As one of the foundational open-source projects in feed-forward 3D reconstruction, OpenLRM has directly influenced and enabled numerous downstream projects and research efforts in the rapidly evolving single-image 3D generation space.

Zero123++
Zero123++ is a multi-view image generation model developed by Stability AI that generates six consistent canonical views of an object from a single input image. Released in 2023 under the Apache 2.0 license, the model extends the original Zero123 approach with significantly improved view consistency and serves as a critical component in modern 3D reconstruction pipelines. Zero123++ takes a single photograph or rendered image of an object and produces six evenly spaced views covering the full 360-degree range around the object, all maintaining consistent geometry, lighting, and appearance. The model is built on a fine-tuned Stable Diffusion backbone with specialized conditioning mechanisms that ensure multi-view coherence. Unlike the original Zero123 which generates views independently and often produces inconsistent results, Zero123++ generates all six views simultaneously in a single diffusion process, dramatically improving 3D consistency. The generated multi-view images serve as input for downstream 3D reconstruction methods like NeRF, Gaussian Splatting, or direct mesh reconstruction, enabling high-quality 3D model creation from a single photograph. Zero123++ is fully open source with pre-trained weights available on Hugging Face, making it accessible to researchers and developers building 3D generation systems. The model has become a foundational component in many state-of-the-art 3D generation pipelines and is widely used in academic research.
