Implementation of the SIGGRAPH 2016 paper gTangle: A Grammar for the Procedural Generation of Tangle Patterns in C++
This project makes use of the OpenGL library GLFW. Most Linux distributions rely on the Mesa3D project to provide their OpenGL implementation. Hence, install Mesa, Make and GCC/g++ first and then the GLFW library.
> sudo apt-get install build-essential libgl1-mesa-dev cmake xorg-dev
> sudo apt-get build-dep glfw3
The input SVG must be located in code/resources/svg/
The input grammar must be placed in code/grammars/
A code/results/svg/ path must exist for the results to be generated.
To generate the tangle for the input SVG using a grammar,
> cd project-lab-team
> cd code
> make all
> ./main_timeline <SVG path relative to code diectory> <Grammar path relative to code directory>
A in detail timeline of the expansion of the grammar and the timestamps will begin printing on the screen. These lines of words may seem un-understandable but don't worry. Go to code/results/svg to see your tangle come to life across frames!
To tag an SVG and give a customised input configuration the GUI can be used as follows,
> cd project-lab-team
> cd code
> make all
> ./main_tag_svg
Select a closed curve in the SVG using a left click, assign a tag in the text box in the GUI window and watch the shapes with the same tag take a unique colour!
Undo all the currently selected shapes using the right click.
Use different number to open different SVGs present in the code/resources/svg/ folder.
