Reality-based 3D-modeling of the Angkorian temples using aerial images

Textures

The texturing was accomplished with in house software. The cropped part of the aerial image together with the field of view and the TIN (Triangle Irregular Network) of facets provide the required information to start a GPU-based off-screen planar orthographic image mapping. The gained texture coordinates define the connection between the cropped image and the 3D model. The field of view was rendered using OpenGL and hardware acceleration. Preliminary results of of Angkor Wat show that with only a small change in the view angle compared to the original image orientation, the texturing from aerial images is possible. To texture the vertical parts like walls or entrances of the monuments efficiently, additional groundbased measurements are needed.
