Title: How to texture a sphere?
Post by: Williamson on July 02, 2009, 11:34:03 am

Hi
For a game I am making, I need to draw a sphere, representing a planet.
However, I cannot work out how do texture a sphere create dwith this code, by using a sf::Image

Code: [Select]

gluSphere(params,25,20,20);
Thanks for any help that can be offered :)

I may have found a solution: does anyone know of an example of the Bind() function of the Image class, used in conjunction with a gluSphere.
Thanks!

It has nothing to do with SFML and sf::Image, you just have to generate proper texture coordinates for your sphere.

If I remember correctly, you can't do that directly with gluSphere.

Take into notice that SFML Clamps the images. You must reset the texture wrapping to GL_REPEAT using glTexParameter after calling sf::Image::Bind()

:)

Goodluck!

Which won't work if there's padding in your texture ;)
