I have a problem with OpenGL: the faces of my cube aren't properly drawn. I tried to disable face culling but it didn't change a thing. By the way, I use sfml 2.1. I also tried to change the indices order of my cube, but it only got worse. Let me show you pictures:
Here's the picture using my first set of indices:
Here's the picture using my second set of indices:
Here are my sets of indices:
GLfloat vertexData[NUM_VERTS * ELEM_PER_POS + NUM_VERTS * ELEM_PER_COLOR] = {
-1.0f, -1.0f, -1.0f, // Positions
1.0f, -1.0f, -1.0f,
-1.0f, 1.0f, -1.0f,
