Blinn lighting and gamma correction
This implementation applies blinn-lighting and gamma-correction techniques.
The user can switch between Blinn and Phong lighting simulations to compare differences. They can also toggle gamma-correction.
Blinn lighting:
Phong lighting:
No gamma-correction:
With gamma-correction:
The code follows examples outlined in:
- https://learnopengl.com/Advanced-Lighting/Advanced-Lighting
- https://learnopengl.com/Advanced-Lighting/Gamma-Correction
Changes over example code
- Ability to toggle between lighting and gamma-correction modes.
- Adjusted various lighting parameters to show the differences between modes.
Running the implementation
-

Interfacing with the implementation
Exiting
Press the ESC key to exit the implementation.
Movement
The movement key-bindings follow an FPS-style scheme:
- W move forward
- S move back
- A move left
- D move right
- Spacebar move up
- Left-Shift move down
- Mouse-movement look around the world.
Rendering manipulations
The numeric keys 1 and 2 are used to switch rendering modes:
-
1 Toggle between Blinn and Phong lighting (Blinn is default)
-
2 Toggle gamma-correction (on by default)
