Agisoft Metashape supports simple anaglyph display mode (for red&blue glasses) as well as hardware stereo mode that assumes polarization glasses and professional-grade hardware (GPU that supports quad-buffered stereo and 3D monitor).
- Hardware stereo display mode in Metashape is supported is only for systems (graphics cards) that support the Quad Buffered Stereo technology.
To use the stereo mode display in the Model view, the parameters of Stereoscopic Display Mode for the current hardware need to be adjusted in the General tab of Preferences dialog available from the Tools menu. Metashape supports Anaglyph, Hardware, Vertical Split and Horizontal Split stereo modes.
