ASCII ART
C++ implementation of image to ASCII art conversion.
The main functionality is in ascii_art in ascii_art.h. For general inputs
I use stb_image_resize.h to resize the input. Otherwise, the only dependency
is the standard library.
There are three executable demos exposing this:
image2ascii
Convert an input image into ASCII art
For example, if you issue:
./image2ascii ../max-schmeling.jpg
You'll see:

spy
Visualize a matrix similar to MATLAB's spy command, but as ASCII art. This
command constructs the cotangent Laplacian of an input triangle mesh and
visualizes this sparse matrix to the terminal:
For example, if you issue:
./spy ../suzanne.obj
You'll see:

ascii3d
Ray trace an input 3D triangle mesh or 3D scene as ASCII art.
For example if you issue,
./ascii3d ../suzanne.obj

This ray-tracer is interactive
Try hitting the hjklJK keys to interact with the 3D scene:
Compilation
mkdir build
cd build
cmake ../ -DCMAKE_BUILD_TYPE=Release
make
Demos depends on libigl, stb, Eigen, Embree.
