Hi! I want to start implementing some post processing effects, but before I do I want to make sure I have the right idea of what I should do. This is what I think I have to do:
- Activate a framebuffer object and clear it
- Render the scene
- Deactivate the framebuffer object and clear the screen
- Set the camera to an orthographic projection
- Render a plane on the screen
- In the shader apply the post processing effects to the scene texture then apply the final scene texture to the plane.
Is that basically correct?
