42-FdF
An introduction project to the graphics branch @ 42.
Reads in a height map to generate a 3D model that the user can interact with!
Installation
To generate an executable for this project run make in the root of the project directory. If the make command fails, check if the minilibx folder is empty. If so, you may have to run git submodule update --init --recursive to initialize and get the files for the minilibx submodule.
This project will only work on MacOS El Capitan/Sierra/HighSierra(maybe) and even then, no promises!
Usage
After running make to generate the fdf executable you can run the program with ./fdf [valid_fdf_file].
A valid fdf file will consist of a matrix of number delimited by spaces. Each number's position represents an (x , y) coordinate with the value of the number itself representing a height (z).
Valid fdf files will always have the same number of elements per row.
Example:
$> cat -e 42.fdf

Output
The program will attempt to render the model described by the fdf file in a graphical window.
The user can interact with the graphical model with the following commands:
Mouse click and drag: Rotate x/y axes
Mouse scroll up/down: Zoom in/out
Arrow keys: Translate x/y axes
'z/x' keys: Rotates z axis
c: Change color modes
p: Turn on/off point only mode
q: Turn on/off Z-buffering
r: Reset map translations, rotations, and scalings
esc: Quit :(
