Texture Transformations

One trick that we can use a texture transformation for is to make sure that a texture is always applied at the same scale, as an object is transformed.

If we apply a texture to an object normally, and then scale the object, the texture appears to stretch:

By applying the same scaling to the texture coordinates as to the geometry, the texture "grows", and does not stretch:

    glMatrixMode(GL_TEXTURE)
     glLoadIdentity()
     glScalef(size, 1, 1)
    glMatrixMode(GL_MODELVIEW)
    glScalef(size, 1, 1)
