ConclusionConclusion

virtual heritage research in Bosnia and virtual heritage research in Bosnia and Herzegovina has just startedHerzegovina has just started

combination of laser scanning and 3D combination of laser scanning and 3D modeling enabled us to create a collection of modeling enabled us to create a collection of virtual modelsvirtual models
