Phong lighting

This implementation applies Phong-lighting techniques.

The Phong-lighting model combines three lighting schemes to simulate realistic lighting effects:

1. Ambient-lighting: simulates overall scattered light.

   

2. Diffuse-lighting: applies the directional qualities of light. The more direct a surface is to a light source, the brighter that surface will be.

   

3. Specular-lighting: simulates bright spots and material shininess.

   

The code follows examples outlined outlined in:

• https://learnopengl.com/Lighting/Colors
• https://learnopengl.com/Lighting/Basic-Lighting
• https://learnopengl.com/Lighting/Materials

Changes over example code

• The light source is given movement.
• Extra cubes are added to show examples of each Phong component. The lighting parameters were chosen for each cube to accentuate the lighting scheme it exemplifies.
  • Cyan: Ambient
  • Blue: Diffuse
  • Green: Specular

Running the implementation

• Navigate the Solution Explorer to path:

  Solution -> 02.lighting -> 01-03.phong_lighting

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

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
