View SourceLearnOpenGL 6.4 - Coordinate Systems (Exercise)
This exercise demonstrates a dynamic camera that orbits around a scene of cubes, showing how the view matrix can be animated to create camera movement effects.
Original C++ Source
This example is based on the original LearnOpenGL C++ tutorial: https://github.com/JoeyDeVries/LearnOpenGL/tree/master/src/1.getting_started/6.4.coordinate_systems_exercise3
Framework Adaptation Notes
This exercise demonstrates:
- Dynamic view matrix calculation for camera movement
- Orbiting camera using trigonometric functions
- Time-based camera animation
- How view transformations affect the entire scene
Key Learning Points
- Camera Movement: How changing the view matrix moves the camera
- Orbital Motion: Using sine and cosine for circular camera paths
- Look-At Matrix: Dynamic camera target and position calculation
- Time-Based Animation: Smooth camera movement over time
Exercise Goals
The exercise typically asks to:
- Make the camera orbit around the scene of cubes
- Keep the camera always looking at the center
- Create smooth, continuous camera movement
- Demonstrate view matrix manipulation
Visual Effect
Shows multiple cubes with an orbiting camera:
- Camera moves in a circular path around the scene
- Camera always points toward the center of the scene
- Cubes remain in their positions but appear to move due to camera motion
- Demonstrates the relationship between camera and world coordinates
