Description
5/5 – (2 votes)
Goal
- Implement 3 types of light sources:
-
- Directional light
-
- Position light (Point light)
-
- Spot light
- Interact and modify the light source in runtime.
- Finish the code in main.cpp, vertex shader and fragment shader

Key Mapping
- Please follow the spec bellow, or you would not get the score of item.
- You must make sure your key mapping is exactly ****same to ours.
- Z/X: switch the model
- T: switch to translation mode
- S: switch to scale mode
- R: switch to rotation mode
Key Mapping
- L: switch between directional/point/spot light
- K: switch to light editing mode
- J: switch to shininess editing mode
Key Mapping
- If you switch mode by T, S, R
- Apply change on Z axis when scroll the wheel
- Apply change on X axis when mouse drag ****horizontally
- Apply change on Y axis when mouse drag ****vertically
- Only rotation should apply X axis when mouse drag vertically, and Y axis when mouse drag horizontally
Key Mapping
- If you switch mode by K
- Apply change on X axis of light’s position when mouse drag horizontally
- Apply change on Y axis of light’s position when mouse drag vertically
- Apply change on diffuse intensity for ****directional or point light, cutoff angle for spot light when scroll the wheel
Key Mapping
- If you switch mode by J
- Apply change on shininess when scroll the wheel
- The shininess is applied to all models.
Report
- Some screen shot
- Description of your program control instructions
- Other special things you have done
