Implement Lights

Implement Light System

Implement a robust lighting system to enhance scene realism and visual quality. This system should support multiple light types and include shadow capabilities. To start I wanna try a cel-shaded shader as this requires very basic materials and should look very effective.

Light Types to Implement:

1. Directional Lights
2. Spot Lights
3. Area Lights

Key Features:

• Support for multiple lights of each type in a scene
• Shadow mapping for all light types
• Efficient rendering to handle many lights simultaneously
• Adjustable properties (color, intensity, range, etc.) for each light

Implementation Details:

• Create a base Light class with common properties
• Derive specific classes for each light type (DirectionalLight, SpotLight, AreaLight)
• Implement shadow mapping techniques appropriate for each light type
• Optimize for performance, potentially using techniques like deferred lighting or tiled forward rendering

Engine Modifications:

• Update shader system to incorporate multiple light sources
• Modify render pipeline to handle shadow map generation and usage
• Implement a light culling system for performance optimization

Considerations:

• Scalability for handling a large number of lights
• Balance between visual quality and performance
• Flexibility for easy addition of new light types in the future
