Abstract
Systems and methods for removing hidden faces in a 3D model, such as a building model are provided. A method for removing hidden faces in a 3D building model may include identifying a 3D building model having hidden surfaces inside the building model. The method may further include adding closing surfaces to the hidden surfaces to form closed hidden surfaces. The method may further include combining the closed hidden surfaces into a single polygon. The method may then include removing the closed hidden surfaces. A system for removing hidden faces in a 3D building model may include a surface identifier, a surface adder, a surface combiner and a surface remover. The removal of unnecessary internal surfaces and artifacts may increase the efficiency of the 3D building model.
