Model loading

This implementation loads a model to the screen with the Assimp library. It also applies directional and point lighting techniques.

Lighting techniques are used to show the model's material qualities:

1. Directional lighting

   

2. Point lighting

   

The code follows examples outlined outlined in:

• https://learnopengl.com/Model-Loading/Assimp
• https://learnopengl.com/Model-Loading/Mesh
• https://learnopengl.com/Model-Loading/Model

Changes over example code

• Lighting modes are implemented to show the material qualities of the Model.
• Ability to switch between mesh, point and fill rendering modes.

Running the implementation

• Navigate the Solution Explorer to path:

  Solution -> 03.model_loading -> 01-03.model_loading_and_lighting

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

• Press F5 to run the project.

Interfacing with the implementation

Exiting

Press the ESC key to exit the implementation.

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.

Rendering manipulations

The numeric keys 1-5 are used to switch lighting and rendering modes:

• 1 Directional lighting
• 2 Point lighting
• 3 Mesh rendering mode
• 4 Point rendering mode
• 5 Fill rendering mode
