# CG Interview about the Exercise

## Information

- Understanding will be checked in individual interviews at the end of the semester.
    - The questions can target conceptual aspects
        - Phong shader theory
        - transformation pipeline
        - how to render objects without the scene graph implementation
        - ...
        - specific implementation details

- Time Slot for project webotic: 13:45-14:00
- An interview is held for each group, which means both members have to be present.
    - The members of the same group will be asked sequentially.

- Each student needs to understand all parts of the project, even those primarily contributed by only one of the group partners.
    - Heightmap
    - Camera Animation
    - Textures
    - Object with multiple parts (plane)
    - Object animation (propeller and door)


## Rendering Pipeline

- Vertices -> Triangles -(Rasterization)-> Fragments -> Coloring -> Rendering

==TODO: Other parts of programmable pipeline are described in much more detail in the 1st slide==

## OpenGL Coordinate System

- Right-handed coordinate system
- By default OpenGL’s virtual camera is placed at the origin of this coordinate system looking in negative z-direction

## Transformation Pipeline

## Texturing (?)

- What are texture units?

## Phong shader


## How to render objects without scene graph implementation




## Custom Interview

- Heightmap
- Camera Animation
- Textures
- Object with multiple parts (plane)
- Object animation (propeller and door)


## TODO: 

- Normal calculation
