Wei, I am not familiar with anyone having integrated GDAL with ogre3d; however, folks do use GDAL as an imagery and elevation model source for lots of 3D rendering engines so I don't foresee any problems. > 2.How could I get the value of (x,y,z) of the Satellite photos file > through gdal? Generally this is accomplished by reading an elevation model from a raster file - often in a format like USGS DEM or DTED, though elevation data can be in quite a variety of formats. The elevation model may be provided in a different coordinate system, and often at a different density than the imagery you are draping over the elevation model. So there is some work to relate pixel/line locations in the drape image with the pixel/line in the elevation model. I would suggest you start by reading up on the GDAL data model, and focusing on the handling of coordinate system, and georeferencing (ie. the GeoTransform).
