[osg-users] transfer data to shader with osg::texture

[Wojciech Lewandowski]

Hi Liu,

You got me interested and I created a repro of your problem. I will send it
in followup mail (to be sure this message passes in case zip attachments
were prohibited and message got blocked).

I think you see a genuine issue.

I have found that texture1D seems to be a problem. When I used texture2D
instead it works. One extra note, though. With GL_RGBA16 no one works
correctly. So internal format needs to be a float format (GL_RGBA16F_ARB,
GL_RGBA32F_ARB, GL_RGB16F_ARB, GL_RGB32F_ARB).

Cheers,
Wojtek
