The party came on the ground from the cave castle. The scenery which spreads in the face of them was the huge ruins of Buddhism. Borobudur, the great Buddhist stupa in Indonesia, built and decorated perhaps before 800AD. I had been to the Borobudur at last summer holiday for materials collection. And I have got many photos of ruins. The 3D data source contains many surface maps and wire frames. Expressly the engraving parts are much complicated. The total volume of data is about 400 MB and much bigger than my other works.  This was very heavy load on PC memory too.
