i think see 2 distant faces blending color darker.

maybe culling not activated.

face culling ability discard face drawing upon condition.

to achieve want, have discard faces not facing camera call backface culling. this:

glenablegl(gl_cull_face);  //(enable face culling) glcullface(gl_back);       //(discard faces)
