ofxPoissonFiller

An OpenFrameworks addon for poisson filling based on convolution pyramids (Farbman et al, 2011).

glyphs.mp4

This add on is header only, inspired by ofxPoissonFill, but unlike ofxPoissonFill, uses GL_RGBA32F textures.

Usage

PoissonFiller pf;
ofFbo fbo;

// ofApp::setup
// ofxPoissonFiller only takes GL_RGBA32F textures
fbo.allocate(_WIDTH, _HEIGHT, GL_RGBA32F);
pf.init(fbo.getWidth(), fbo.getHeight())

// ofApp::update
pf.process(fbo);

// ofApp::draw
pf.getResult().draw(0,0);

Reference

This addon is not a re-implementation of the convolution pyramid algorithm from scratch, but is an effort to port existing to work into OpenFrameworks.

This addon is heavily based on:

• kosua20/Rendu
• LingDong-/ofxPoissonFill
• orx-poisson-fill
• patriciogonzalezvivo/lygia
