JSM2D

Note

This is a 2D demo implementation of alexaschor/JuliaShapeModulus. For the code used to generate the examples in the paper, check out that repo.

Building:

Requires OpenGL and GLUT. ./bin/interactive uses ANTTweakBar, but that's bundled with this code and should just build with make.

1. git clone https://github.com/alexaschor/DQM2D
2. cd DQM2D
3. mkdir bin
4. If on Linux, go to include.mk, comment out the Mac part and uncomment the Linux part. For either platform you may need to change CXX to whichever g++ you want to use.
5. make

SDF from SVG (only supports single polygons):

1. ./bin/svgToPoly data/XXX.svg data/XXX.poly
2. ./bin/polyToSDF data/XXX.poly <RESOLUTION> data/XXX.sdf

SDF from PPM (will flip image vertically, should be white inside shape and black everywhere else):

Uses a "dead reckoning" transform, so I don't think it's exact but it works fine for this purpose.

1. ./bin/ppmToSDF data/XXX.ppm <OUTPUT RESOLUTION> data/XXX.sdf

Generate/view a Julia set:

1. To run ./bin/interactive, you'll need to set your DYLD_LIBRARY_PATH on Mac, or LD_LIBRARY_PATH on Linux. make setPath in projects/interactive will generate the command you need to run before executing ./bin/interactive
2. ./bin/interactive data/XXX.sdf
3. Most of the controls are on-screen and the rest are from fieldViewer3D. LMB to pan, RMB and drag to zoom. N togges auto-normalizing, and arrow keys adjust scale/bias. By default there's just the one config window open, but there's a few more minimized to the bottom left of the viewing window.
