42_FdF

This project aims to represent the wire mesh of a map in 3D.

Example

Example of a Conical representation.

Expected Result

The objective is to create graphically the schematic representation in “wireframe” (or "Fil de Fer" in French) of a map in relief by connecting different points (x, y, z) by segments.
The coordinates of the map will be stored in a file passed in parameter, here is an example with the map "42.fdf":

Each number corresponds to a point in space:

• The horizontal position corresponds to its abscissa.
• The vertical position corresponds to its ordinate.
• The value corresponds to its altitude.

By executing the command ./fdf 42.fdf, we should see something similar to the picture below.

A minimal of two projections were expected.
In my case, three types of projections are included in the program:

• Isometric
• Parallel
• Perspective

MinilibX

This project use the "MinilibX" library.
The installation process include the compilation from sources, the linking and the creation of the static library.

Some external packages can be necessary, depending on your OS: https://github.com/42Paris/minilibx-linux

A MacOs version is included in the "lib" folder. In this case, update the makefile for "minilibx-macos".

Install

Create or update the "fdf" program from sources.

make

Reinstall

Recompile completely the program.

make re

Clean

Delete object files created during installation.

make clean

Uninstall

Delete object files but also the compiled program.
It will not affect the source code.

make fclean

Usage

./fdf test_maps/42.fdf

MAN (complete user manual)

./fdf -h

Screenshots

More screenshots are available in the "screens" folder.

Notes

I recommand to use the "clang" compiler because "gcc" generates linking error with the minilibx.
Check that clang compiler is installed on your system.

If there is permission issue:

chmod 774 lib/minilibx-linux/configure
