Lighting

Lighting

Lighting class is contained by Scene. It allows you to add, remove, update lights on scene that have an influence on object material's color.

• Ambient Lighting

• Dynamic Lighting

  • Point Light
  • Directional Light
  • Spot Light

• Static Lighting

• Ambient

  This type of lighting influences all objects on a scene. (Skybox is influenced too)

  glm::vec4 ambient_color

  First three components is RGB color, A component is intensity.

• Dynamic

  It is runtime lighting calculations are proccessed for each frame in fragment shader. It allows you to move lights around, change its color, radius and other properties.

  • PointLight

    Influences objects in a specified sphere.

    struct PointLight {
      glm::vec4 position;
      glm::vec4 color;
      float constant {1.0f};
      float linear {0.7f};
      float quadratic {1.8f};
      float radius;
    };
    
    `PointLight(const glm::vec3& position, const glm::vec4& color, float radius) noexcept;`
    
    

  • DirectionalLight

    struct DirectionalLight {
      glm::vec4 direction;
      glm::vec4 color;
    };
    

  • SpotLight

    Not implemented yet.

• Static

  Baking maps is not in the nearest future : /
