Open Source 3D Generation Tools
3D generation uses computational methods, including machine learning, to create three-dimensional objects, scenes, or environments from inputs such as text, images, or other 3D data. It can reduce the time and expertise needed to build digital assets, support rapid visualization, and make it easier to produce variations for design, simulation, games, and virtual experiences. Results may include meshes, textured models, or complete environments, with quality and editability depending on the method and input.
Open source tools in this area include pretrained models, training frameworks, inference pipelines, and applications for generating or refining 3D assets. When comparing options, consider output formats and quality, license terms, hardware and software requirements, documentation, maintenance activity, and integration with existing 3D workflows. These tools are useful to artists, developers, researchers, and designers exploring procedural content, asset creation, or new 3D interfaces.

PartCrafter: Structured 3D Mesh Generation via Compositional Latent Diffusion Transformers
PartCrafter is an innovative structured 3D generative model that enables the creation of complex 3D meshes and scenes from a single RGB image. Accepted at NeurIPS 2025, this project leverages compositional latent diffusion transformers to jointly generate multiple parts and objects in one shot. It offers powerful capabilities for both 3D object and scene generation, making it a valuable tool for researchers and developers in the field.

HunyuanWorld-1.0: Generating Immersive 3D Worlds from Text or Pixels
HunyuanWorld-1.0 is an innovative GitHub repository from Tencent-Hunyuan, designed for generating immersive, explorable, and interactive 3D worlds. It leverages advanced models to create detailed 3D environments directly from text descriptions or input images. This project aims to overcome limitations in existing 3D world generation by offering 360° immersive experiences and mesh export capabilities.
