Yes! Got it! Though there is something terribly wrong with my depth test I think.
GL11.glEnable(GL11.GL_CULL_FACE);
GL11.glCullFace(GL11.GL_BACK);
GL11.glFrontFace(GL11.GL_CW);
GL11.glEnable(GL11.GL_DEPTH_TEST);
GL11.glDepthMask(true);
GL11.glDepthFunc(GL11.GL_GEQUAL);
GL11.glDepthRange(0.0f, 1.0f);
If i change it to GL_LEQUAL seems like every depth test fails and I see nothing. Probably there is something wrong with the data or my perspective matrix, maybe I'm not drawing in the correct order.
