osgdem无法生成地形，请教各位大侠

wangan2010

今天终于将VPB编译完了，同时也获取了GDAL。
接下来便迫不及待的按照FlySky的方法来生成地形。但是，呵呵，地形根本就没有出来
我的步骤是这样的，命令行依次输入如下：
1、gdal_translate F:\DEM\ps_height_16k.png F:\DEM\ps_height_16k.tif
2、gdaladdo -r average F:\DEM\ps_height_16k.tif 2 4 8 16 32
3、gdal_translate F:\DEM\ps_texture_16k.png F:\DEM\ps_texture_16k.tif
4、gdaladdo -r average F:\DEM\ps_texture_16k.tif 2 4 8 16 32
5、osgdem --xx 10 --yy 10 -t F:\DEM\ps_texture_16k.tif --xx 10 --yy 10 -d F:\DEM\ps_height_16k.tif -l 6 -v 0.1 -o puget.ive -a pegout.osga
（我将下载的到的ps_height_16k.png和ps_texture_16k.png都放入了F:\DEM中，生成的两个tif也放入了这文件夹中。）

但是最终结果却是ive没有生成，osga也是没有生成。只是多了一个名为“puget_root_L0_X0_Y0”文件夹。

请问各位大侠，这到底是怎么回事？

再次对论坛中无私奉献的大侠们表示感谢！

和我遇到的问题一样的,我加上--no-mip-mapping就可以了,不知道什么原因

linuxwfgu

应该是显卡的问题

亲测可行

poseidon

恩，亲测可行，只是不知道原理是什么？
