Lightmaps and lighting techniques

This implementation applies Lightmaps, directional-lighting, point-lighting and spot-lighting techniques.

Lighting techniques are used to create four environmental lighting schemes:

1. Balanced mode: simulates a balanced lighting environment.

   

2. Night mode: simulates a night-time environment.

   

3. Radioactive mode: simulates a toxic/radioactive environment.

   

4. Volcano mode: simulates a volcanic environment.

   

The code follows examples outlined outlined in:

• https://learnopengl.com/Lighting/Lighting-maps
• https://learnopengl.com/Lighting/Light-casters
• https://learnopengl.com/Lighting/Multiple-lights

Changes over example code

• Tweaked lighting parameters to create the night, radioactive and volcano modes.
• Added the ability to switch between modes with the numeric keys 1-4.

Running the implementation

• Navigate the Solution Explorer to path:

  Solution -> 02.lighting -> 04-06.lightmaps_and_environmental_lighting

• Left-click the project name and select Set as Startup Project from the pop-up window.

• Press F5 to run the project.

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.

The numeric keys 1-4 are used to switch lighting modes:

• 1 Balanced mode
• 2 Night mode
• 3 Radioactive mode
• 4 Volcano mode
