# ofxPoissonFiller

An OpenFrameworks addon for poisson filling based on convolution pyramids

([Farbman et al,

2011](https://pages.cs.huji.ac.il/danix-lab/cglab/projects/convpyr/)).

https://github.com/somecho/ofxPoissonFiller/assets/26333602/c45370d8-e3ae-411e-be8f-86a69301a673

This add on is header only, inspired by [ofxPoissonFill](https://github.com/LingDong-/ofxPoissonFill), but unlike ofxPoissonFill, uses GL_RGBA32F textures.

## Usage

```cpp

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](https://github.com/kosua20/Rendu)

- [LingDong-/ofxPoissonFill](https://github.com/kosua20/Rendu)
