Infinite Vector Graphics c++

Dependency:

libigl

Installation

First, compile static library libigl:

cd libigl
mkdir build
cd build
cmake .. -DLIBIGL_USE_STATIC_LIBRARY=ON
make -j8

Then, compile our code with

mkdir build
cd build
cmake ..
make -j8

Usage:

We provide four excutable commands bem_brute for standard BEM with brute force computation,hybrid_brute for our hybrid method with brute computation, and hybrid_fmm for Hybrid method + FMM, and hybrid_fmm_adap for hybrid method + FMM + Adaptive Subdivision.

For bem_brute, hybrid_brute, and hybrid_fmm, run command input_file.txt to run example. You can find input data for diffusion curve in data folder. For example, try running follwing command:

hybrid_fmm ../data/cherry.txt

This should generate the output cheryy.png file in result folder:

The resolution of the image will be determined as the same size as the pre-defined image size. You can customize the resolution by specifying resolution of width and height as following:

hybrid_fmm ../data/cherry.txt 1024(resolution of width) 1024(resolution of height)

or you can simply specify a scaling value that will be multiplied o its pre-defined image size. For example,

hybrid_fmm ../data/cherry.txt 2

will output 1024x1024 resolution of image which is twice size of pre-defined image size of 512x512

For hybrid_fmm_adap, run hybrid_fmm_adap input_file.json to run example with zoom-in. For example, try running follwing command:

hybrid_fmm_adap ../data/cherry.json

This should generate the sequence of .png files in result folder:
