The method for 3D visual mapping using 3D stereoscopic video content records live 2D perspective white images mapped to architectural or other 3D objects having abstract shaped surfaces to create 2D perspective masks fitting the surface shapes. Each abstract surface area is covered by a dedicated projector and controller. The mapping is locked into place on a pixel grid, the project being logically recorded-rendered onto a hard drive at native resolution to produce a 2D master mask, which is separated into sub-masks determined by the individual areas of the 2D master mask. Each 2D sub-mask is applied as a video layer and used to mask areas around 3D stereoscopic video content in its timeline. The 2D masked-mapped stereoscopic 3D video can be played on 3D stereoscopic projectors. A common clock synchronizes the processors for playback of the 3D content on the 3D surface areas.
