[gdal-dev] RPC to geotransform converting

Hi, I have a GeoTIF file and file with RPC information next to it (*.txt). Is there a way to transform this raster to a normal geotiff without displacement (with geotransform inside) or is it fundamentally impossible? I've tried to achieve it with gdalwarp but in this case the result of the transf
