Description
ofxVFX is an openframeworks addon for visual effects.
Environment
openFrameworks 0.10.0
Usage
Copy the
shaders/ofxVFX/ directory to your bin/data/ directory. Change your main.cpp to use programmable shader.
``````
int main()
{
ofGLWindowSettings s;
s.setGLVersion(4, 1); // or the version you use
s.setSize(1920, 1080);
ofCreateWindow(s);
ofRunApp(new ofApp());
}
``ofxVFX mVFX;
In your setup() function, call mVFX.addPass<ofxVFX::RenderPass>() to add the effect pass and then call mVFX.generate(width, height) to setup each effect.
mVFX.addPass<ofxVFX::BloomPass>();
mVFX.addPass<ofxVFX::OpticalFlowPass>();
mVFX.addPass<ofxVFX::CRTPass>();
mVFX.addPass<ofxVFX::EdgePass>();
mVFX.addPass<ofxVFX::SymmetryPass>();
mVFX.addPass<ofxVFX::StreakPass>();
mVFX.addPass<ofxVFX::NoiseWarpPass>();
mVFX.addPass<ofxVFX::CAPass>();
mVFX.addPass<ofxVFX::InvertPass>();
mVFX.addPass<ofxVFX::MNCAPass>();
mVFX.addPass<ofxVFX::InkPass>();
mVFX.addPass<ofxVFX::ZoomBlurPass>();
mVFX.generate(width, height);
You have to call mVFX.update(time) function in rendering loop to update effects.
mVFX.update(ofGetElapsedTimef());
Render your scene between mVFX.begin() amd mVFX.end().
mVFX.begin();
// some codes to render scene
mVFX.end();
Call mVFX.draw(0, 0, width, height) in your draw() function.
void draw()
{
mVFX.draw(0, 0, width, height);
}
You can change effect parameters like below. Check the example for more info!
// Bloom
mVFX.getRenderPassPtr(int renderPassIndex)->setBloomBlurScale(mBlurScale);
