I dont get it. Why when in OpenGL you load in the vertices as the following, in figure 1. You get a triangle? But for Figure 2, you get a sort of rotate triangle where the top point of the triangle is pointing to the left-direction. How come OpenGL interprets the data quite differently? And how are they different?Figure #1float vertices[] = { -0.5f, -0.5f, 0.0f, 0.5f, -0.5f, 0.0f, 0.0f, 0.5f, 0.0f };Figure #2float vertices[] = { -0.5f, -0.5f, 0.5f, -0.5f, 0.0f, 0.5f, };

I dont get it. Why when in OpenGL you load in the vertices as the following, in figure 1. You get a triangle? But for Figure 2, you get a sort of rotate triangle where the top point of the triangle is pointing to the left-direction. How come OpenGL interprets the data quite differently? And how are they different?
Figure #1
float vertices[] = {
-0.5f, -0.5f, 0.0f,
0.5f, -0.5f, 0.0f,
0.0f, 0.5f, 0.0f
};
Figure #2
float vertices[] = {
-0.5f, -0.5f,
0.5f, -0.5f,
0.0f, 0.5f,
};
