Hi, i would create a tiled Terrain with osgdem . i have my heightMap and colourMap made with WorldMachine a terrain editor http://www.world-machine.com/ . With the heightmap i have no problem but with the colour map i got weird artifacts. This is my process:
i got the 8 bit .png colour map from WM. gdal_tranlsate colourMapDistorted_gdal_tr_16bit_02.png colourMapDistorted_gdal_tr_16bit_02.tif gdaladdo -r average colourMapDistorted_gdal_tr_16bit_02.tif 2 4 8 16 32 then osgdem: osgdem -t data/colourMapDistorted_gdal_tr_16bit_02.tif -d data/icebergHeightMapDistorted02_gdal.tif -l 8 -v 1 -o iceberg.ive -a iceberg.osga i tried with other picture format, WM may output .bmp(8bit) ,png(8bit) .tiff(8bit) ,png(16bit) .tiff(16bit). i tired with all format but with no luck. The only difference that i noticed is that when i average the .tif(16bit) i got an alpha image instead of a RGB image . Who can enlight in the right direction? Thank you!
