gluSphere texture poles

Hello,

I have created a gluSphere which has normals pointing inside, because I would like to position myself inside the world.

I have then tried to texture it with a jpg. The problem is that the poles of the sphere, when textured, are in z coordinates, whereas they should be on y coordinates.

Is it possible to define this, or do we just have to rotate the sphere ?

Here’s the sphere definition code :

	theWorldObj = gluNewQuadric();
	gluQuadricDrawStyle(theWorldObj, GLU_FILL);
	gluQuadricNormals(theWorldObj, GLU_SMOOTH);
	gluQuadricOrientation(theWorldObj, GLU_INSIDE);
	gluQuadricTexture(theWorldObj, true);

Here’s the code in the main which binds the texture :

		//render some geometry
		//activate texturing
		glEnable(GL_TEXTURE_2D);
		glBindTexture(GL_TEXTURE_2D,worldImage);

		//translations and rotations inside the world
		glTranslatef(a_d_Key, 0.0f, w_s_Key);
		glRotatef(left_right_Key,0.0,1.0,0.0);
		glRotatef(up_down_Key,1.0,0.0,0.0);
		
		gluSphere(theWorldObj, worldRadius, 30, 30);
		glDisable(GL_TEXTURE_2D);

Thanks,
Manojo

I’m not 100% sure but I guess you would simply have to rotate/transform the sphere so that it is to your liking.
