42 FdF

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 test_maps directory. One of the popular maps is test_maps/42.fdf.

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

FDF Usage

Usage:		FDF		fdf_file

Controls:

	[Esc]        -> Exit the program.
	[R]          -> Reset the map.
	[M]          -> Colorize this shit!.
	[B][N]       -> Zoom in and zoom out.
	[J][K]       -> Spiky time!
	[Space]      -> Change the camera(isometric <-> plain).
	[W][A][S][D] -> Move the map.
