MicMac vs PhotoCatch

MicMac is free, open-source desktop software for reconstructing 3D models from imagery. Developed at IGN and ENSG within the LASTIG lab, it runs on Linux, macOS and Windows under the CECILL-B license. It supports frame cameras, pushbroom sensors and scanned analogue images, along with camera calibration models and dense image matching for deformation studies. Outputs can include point clouds, 3D models and ortho-imagery in a desired coordinate system. Intermediate results in open formats let users work at different stages, and quality indicators include bundle adjustment residuals, covariance matrices, parameter sensitivity and correlation images. The C3DC command computes a point cloud from oriented images; AperiCloud creates a sparse cloud with camera positions and orientations for viewing in MeshLab, but does not support 64-bit PLY. MicMac is adapted to big datasets and was initially built for experts and researchers, with use also described in architecture, archaeology and forestry. Documentation, tutorials, a wiki and user forum are available. Building from source involves multiple dependencies, and the Mac guide cautions that a current revision may not compile or may be unstable on a given OS.

PhotoCatch creates 3D models from photos and video, with capture and editing options on macOS and iOS. The desktop app can build models from separate photos, video, or both, then provides texture editing, AR optimization, transform, and crop tools. It exports USDZ and OBJ files; the App Store page says USDZ exports are ready for AR Quick Look and OBJ files work with almost any 3D software. PhotoCatch Cloud brings photogrammetry and 3D editing to mobile for capture, editing, and sharing on site. Its Depth Capture feature is intended to keep a model at the same scale as the real-world object. The maker presents PhotoCatch for personal, business, and enterprise uses such as AR, VR, construction, real estate, VFX, and online shopping. Desktop requirements are macOS 12 Monterey or later and Apple Silicon; some Intel Macs may work with 16 GB RAM and a compatible AMD GPU with 4 GB VRAM. The free plan is free. Monthly options are Essentials at 4.99 USD, Pro at 9.99 USD, Small Business at 19.99 USD, and Corporate at $49.99 a month.
