Download Regard3D – Free Photogrammetry Software for 3D Model Reconstruction

Regard3D is a free, open-source photogrammetry program that converts a series of ordinary photographs into detailed 3D models. By analyzing overlapping photos taken from multiple angles, it computes a dense point cloud and then reconstructs a textured 3D surface — all without any special hardware or expensive software licenses.

The workflow in Regard3D follows established Structure-from-Motion (SfM) and Multi-View Stereo (MVS) pipelines: import your photos, detect and match feature points, compute camera positions, build a sparse point cloud, densify it, and generate a final mesh with textures. The results can be exported in standard 3D formats for use in Blender, MeshLab, or any other 3D application.

Regard3D is ideal for archaeologists, architects, hobbyist makers, and anyone who wants to create 3D scans of objects, buildings, or environments using nothing more than a digital camera or smartphone.

Key Features

• Converts ordinary photos into dense, textured 3D point clouds and meshes
• Uses Structure-from-Motion (SfM) and Multi-View Stereo (MVS) algorithms for accurate reconstruction
• Handles hundreds of input images for large-scale scene reconstruction
• Interactive 3D viewer built in for previewing point clouds and meshes during the pipeline
• Exports to OBJ, PLY, and other standard 3D formats compatible with most 3D applications
• Cross-platform — available for Windows, Linux, and macOS
• Free and open-source with no usage restrictions
