FdF @ 42

Screen

A simple 3D height-map renderer. You can rotate models, color is defined by relative height in the map. More features planned!

Features

• Simple file format definition (array of space-separated integers)
• 3D rotations with the mouse
• Camera controls (zoom, translate)
• Pretty color gradients!
• Double-buffered
• Line clipping

Planned features

• Other projections (right now it's just orthographic)
• Different view modes: point map, wireframe, and filled
• More color modes: gradient, file-defined and z-buffer
• Depth shader
• Multithreaded calculations (OpenCL even?)
• Anti-aliased rendering
• Level-of-detail (less points when you zoom out on huge maps)

Compiling and running

Run make. An executable will compile. Currently only tested on OS X.

Run it with ./fdf [map]. A bunch of sample maps are provided in the maps directory. The one in the screenshot above is maps/42.fdf.

Controls are: drag with left click to rotate, drag with right to zoom, drag with both to move around.
