3. Introduction how to preserve cultural heritage? how to preserve cultural heritage? Bosnia and Herzgovina – heritage destroyed by age and the war Bosnia and Herzgovina – heritage destroyed by age and the war computer graphics should help the archaeologists and historians using advanced technologies computer graphics should help the archaeologists and historians using advanced technologies

7. Stećak – Sun simulation orientation of stećaks was important for heretic Christians orientation of stećaks was important for heretic Christians stećaks are moved from their original locations and oriented in a wrong way stećaks are moved from their original locations and oriented in a wrong way we created sun simulation to compare orientations towards the sun we created sun simulation to compare orientations towards the sun

15. Conclusion virtual heritage research in Bosnia and Herzegovina has just started virtual heritage research in Bosnia and Herzegovina has just started combination of laser scanning and 3D modeling enabled us to create a collection of virtual models combination of laser scanning and 3D modeling enabled us to create a collection of virtual models presentation through interactive CD-s and web presentation through interactive CD-s and web applications expanded with virtual and real avatars telling stories from BH tradition applications expanded with virtual and real avatars telling stories from BH tradition

16. Future work stronger collaboration with archaeologists and historians stronger collaboration with archaeologists and historians expanding virtual heritage collection expanding virtual heritage collection virtual museum collections virtual museum collections application of digital storytelling techniques in virtual environments application of digital storytelling techniques in virtual environments
