Something like that: for (int i = 0, int numBlobs = contourFinder.blobs.size(); i < numBlobs; ++i){ ofxCvBlob & blob = contourFinder.blobs[i]; ofVec2f c( blob.centroid.x, blob.centroid.y );...

Oops just saw this. This might not be what you are looking for but in my ofxOpenVJ during a hackathon I created a scene that had box2d particles along with openCV outlines - you can dig around here :...

hey @elliot - off the top of my head you could do this by using the 'drawSubsection()' method of ofImage. http://openframeworks.cc/documentation/graphics/ofImage.html#!show_drawSubsection cheers!

I have a class "Wave" and inside I'd like to access the slider value 'waveSpeed' but it gives me linking errors. z += ofApp::waveSpeed * deltaTime; That gives me invalid use of non-static If I make it...
View ArticleUsing ofxGui slider values outside of ofApp
the easiest way to do this is either pass the value through to the wave object from ofApp, or in the .cpp file of wave (you can't do this in the .h file) you can do: #include "ofApp.h" // note you...

hello, I don't know if this is the way the gui slider is supposed to be used. I mean it is ok to modify a class slider from ofApp, but not the other way around. maybe you should declare a listener...

ps: the Krzysztof code as I recall is really more about input then drawing, it just does smoothed input ala paper -- it helps make fast input lines look less jagged.

Thank you both. This seems like functionality that would be used often, no? To have a class' behavior modified from sliders? Gallo, with your method, in the update() function, shall I do something to...

I think you are using the :: wrong here. usually you use :: for static variable, here if you had a wave object, ie: wave myWave you'd access a variable called speed inside it like: myWave.speed =...
View ArticleUsing ofxGui slider values outside of ofApp
every wave should have a speed, you can update it by listening the slider in ofApp (although the best approach here would be to declare speed in wave as ofParameter then populate the ofApp gui with...

the easiest, and cleanest way to use this is to use ofParameter to represent the speed and then pass that to a panel which will create a slider automatically. take a look at guiFromParametersExample...

i think @arturo has the best approach... but how would you manage say 100 of waves ? i mean can you manage all the 100 waves with one slider ?

you can create the parameter as a static variable like: //.h class Wave{ public: ... static ofParameter<float> speed; } //wave.cpp static ofParameter<float> Wave::speed{"wave...
