In this video, we dive into the core rendering and interaction loop of our 3D Solar System simulation built with OpenGL and FreeGLUT.
This part of the project controls how the entire scene is drawn, animated, and interacted with — including camera movement, zooming, planet focus, mouse input, and continuous updates.
🔹 What you’ll learn in this video:
Understanding the display() function as the heart of OpenGL rendering
Rendering different camera modes: normal view vs selected planet view
Implementing a smooth camera orbit system using angles and distance
Creating a planet-follow camera with interpolation for natural motion
Handling continuous animation with the idle() update loop
Processing mouse input for zooming, clicking, and camera rotation
Managing multiple interaction states without breaking rendering flow
This video ties together all previous systems — rendering, interaction, UI, and animation — into a smooth and responsive user experience.
