   How to fix thin lines between polygons?
  Hi,I'm in the process of coding/debugging a skybox, and I've run into a small problem: there are thin lines between the faces of the cube I'm using. Here's a screenshot to illustrate:And a magnified crop:This is the code I'm using the draw the skybox (C++):double hel = m_EdgeLength / 2.0;RenderDevice::get().disable( GL_DEPTH_TEST );// Topm_Textures[0]->apply();glBegin( GL_QUADS );glTexCoord2f( 0.0, 0.0 );glVertex3d( -hel, hel, -hel );glTexCoord2f( 0.0, 1.0 );glVertex3d( hel, hel, -hel );glTexCoord2f( 1.0, 1.0 );glVertex3d( hel, hel, hel );glTexCoord2f( 1.0, 0.0 );glVertex3d( -hel, hel, hel );glEnd();// Leftm_Textures[1]->apply();glBegin( GL_QUADS );glTexCoord2f( 0.0, 0.0 );glVertex3d( -hel, hel, hel );glTexCoord2f( 0.0, 1.0 );glVertex3d( -hel, -hel, hel );glTexCoord2f( 1.0, 1.0 );glVertex3d( -hel, -hel, -hel );glTexCoord2f( 1.0, 0.0 );glVertex3d( -hel, hel, -hel );glEnd();// Frontm_Textures[2]->apply();glBegin( GL_QUADS );glTexCoord2f( 0.0, 0.0 );glVertex3d( -hel, hel, -hel );glTexCoord2f( 0.0, 1.0 );glVertex3d( -hel, -hel, -hel );glTexCoord2f( 1.0, 1.0 );glVertex3d( hel, -hel, -hel );glTexCoord2f( 1.0, 0.0 );glVertex3d( hel, hel, -hel );glEnd();// Rightm_Textures[3]->apply();glBegin( GL_QUADS );glTexCoord2f( 0.0, 0.0 );glVertex3d( hel, hel, -hel );glTexCoord2f( 0.0, 1.0 );glVertex3d( hel, -hel, -hel );glTexCoord2f( 1.0, 1.0 );glVertex3d( hel, -hel, hel );glTexCoord2f( 1.0, 0.0 );glVertex3d( hel, hel, hel );glEnd();// Backm_Textures[4]->apply();glBegin( GL_QUADS );glTexCoord2f( 0.0, 0.0 );glVertex3d( hel, hel, hel );glTexCoord2f( 0.0, 1.0 );glVertex3d( hel, -hel, hel );glTexCoord2f( 1.0, 1.0 );glVertex3d( -hel, -hel, hel );glTexCoord2f( 1.0, 0.0 );glVertex3d( -hel, hel, hel );glEnd();// Bottomm_Textures[5]->apply();glBegin( GL_QUADS );glTexCoord2f( 0.0, 0.0 );glVertex3d( -hel, -hel, hel );glTexCoord2f( 0.0, 1.0 );glVertex3d( hel, -hel, hel );glTexCoord2f( 1.0, 1.0 );glVertex3d( hel, -hel, -hel );glTexCoord2f( 1.0, 0.0 );glVertex3d( -hel, -hel, -hel );glEnd();Z buffer testing is turned off, and blending is also turned off. I know it's probably not a terribly complex problem, but any help that you guys can give me would be greatly appreciated.Thanks in advance!   
  What are your settings for the textures? Did you set up the glTexParameteri(GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);glTexParameteri(GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);;  I set the clamp values you suggested, and it seems to be fixed now! Thanks!
