[osg-users] how to render 16bit depth image

[Bruno Oliveira]

Hello,

I have a 16bit per channel, 4 channel, image. The format is short
(uint16_t). Note that this image is scaled to the full 16bit depth [0,
65536]


I have this code that works well for a 8bit, 4 channel image:

osg::ref_ptr<osg::Image> image = new osg::Image();
 image->setImage(ImageSize, ImageSize,1,
GL_RGBA8,
GL_RGBA,
GL_UNSIGNED_INT_8_8_8_8_REV,
MyDataPtr,
osg::Image::NO_DELETE);



Now I want to por this to 16bit depth.
How is this done?

I tried

 image->setImage(ImageSize, ImageSize,1,
GL_RGBA16UI,
GL_RGBA,
GL_UNSIGNED_INT_8_8_8_8_REV,
MyDataPtr,
osg::Image::NO_DELETE);

But this yields all black textures. How can I do this without converting my
16bit image pixel data?
