void main() { FragColor = vec4(vColor, 1.0); }
Before 3.3, managing vertex data was a chore of binding and unbinding buffers. The VAO changed this by acting as a "wrapper" or "saved state" for all the vertex attribute configurations. A developer could set up a VAO once—defining that position data is in buffer A at offset 0, and normal data is in buffer B at offset 12—and then restore that entire configuration with a single glBindVertexArray() call. This reduced CPU overhead and driver validation, enabling the rendering of complex scenes with thousands of individual objects.

Here's a simple example of an OpenGL 3.3 program that renders a triangle:
void main() { FragColor = vec4(vColor, 1.0); }
