Free photogrammetry for detailed 3D models
Meshroom is a free, open-source photogrammetry app that converts photographs into detailed 3D models. Developed by AliceVision, it uses a structured reconstruction pipeline to analyze images taken from multiple angles and generate textured geometry. The software targets digital artists, designers, and technical users who want to create accurate 3D assets from real-world objects. Its visual workflow reduces coding requirements while still exposing advanced processing controls for users who need precision and flexibility.
Meshroom uses a node-based interface where each stage of the photogrammetry pipeline appears as a connected processing block. Users can drag and drop images into the workspace, triggering automatic feature detection, camera matching, depth map generation, and texturing. While the default pipeline runs automatically, individual nodes can be adjusted manually for refinement. This balance between automation and control makes Meshroom approachable for beginners while still supporting experienced users who want to fine-tune reconstruction parameters.

Hardware requirements and processing demands
Meshroom is hardware intensive and requires a 64-bit version of Windows. For full functionality, it depends on an NVIDIA GPU with CUDA support to compute depth maps efficiently. Systems without compatible GPUs may face limited functionality or failed processing steps. Reconstruction times vary depending on image count and resolution, and complex projects can take considerable processing time. High-quality, well-lit photographs improve alignment accuracy, though identical camera settings across all images are helpful rather than strictly required.
Practical considerations for Windows users
Meshroom does not focus on simplified one-click modeling but instead provides a structured and technically transparent workflow. It supports advanced formats and allows users to inspect each reconstruction stage visually. There is no deep integration with third-party creative platforms, so exports must be transferred manually into other 3D software. Despite its processing demands, Meshroom remains a strong choice for Windows users seeking a free, technically robust photogrammetry tool with professional-grade output potential.
