OpenGL: Can't get a texture mapped correctly on a sphere.
 
1 Attachment(s)
As the title says. Digged arround all weekend and didn't find a solution.

Code:
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
Tried setting GL_TEXTURE_WRAP_* to GL_CLAMP but nothing.

Hope someone has a clue. I'm new to opengl es.

Btw. the texture dimension is 800x400.

are you sure the texture is rotated correctly? (like, not 90 degrees away)

It maps corectly on windows and linux desktop. And yes the visible half gets mapped correctly and the rest... well as in the screenshot..

Hm, if it does show only one half, have you tried redimensioning the texture so it is half as wide?

Exactly the ame result when resizing it to 400x400...

a wasteful workaround would be to double the image, two copies side to side
