A basic 3D rendering engine for height maps, represented as wireframes

Note : Only works on macOS 10.12 and later

• Camera controls (zoom, rotation & translation)
• Color gradient & single color modes
• Supports colors in map files
• Dots-only mode
• Perspective (default) & orthographic projections
• Line clipping
• FPS Counter and help/debug panels
• Circular frame-buffering
• Multithreaded drawing & frame cleaning

First, clone and pull the submodules

$ git clone https://github.com/bil0u/fdf.git
...
$ git submodule update --init

A Makefile is provided, just run in your shell

$ make

or call it from a parent one with the rule make -C ./<fdf_path>

To run, just type

$ ./fdf [path/to/map]

A bunch of samples maps are provided in the maps directory.

Keyboard control only (Default mapped to US). Mouse is not supported for the moment.

• R / T
  Respectively switch beetween rotate (default) & translate modes
• Arrows
  Control rotation & translation
• Z / A
  Respectively switch beetween zoom (default) & altitude modes
• + / -
  Control zoom & altitude values

• C
  Switch beetween gradient (default) & mono color mode
• V / X
  Respectively increase & decrease the pinned altitude for current color set
• Space
  Select next color or color gradient depending on the actual mode

• Alt left
  Switch between wireframe (default) & dot modes
• P
  Switch beetween perspective (default) & orthographic projections

• H
  Show/hide help panel
• D
  Show/hide FPS counter & debug infos

• Shift left / right
  Respectively slow down & speed up the controls sensitivity
• Command + <key>
  Locks the <key, useful for rotations/zoom. When locked, repress the <key once to unlock

• Delete
  Reset view to original position
• Q / Escape
  Quit the program
