Uses 42-school's X11 programming library MLX to visualize multiple 3D-to-2D projections of basic depthmaps based on ARC/INFO ASCII grid format.
Currently features an isometric view with full 3D rotation and orthographic front/elevation view with distance-based shading.
Both views include options for RBG hue rotation, depth-based shading/highlights, unlimited zoom and 2D translation.
Compiling on Linux requires packages xorg libxext-dev libbsd-dev
Compiling on MacOS is untested, expect fiddling with header files.
