Hi

I am trying to use the OpenCV library with a sketch which already uses the OpenGL library.. but it seems as thought that these do not work together..  The introduction of the OpenGL library distorts the redrawing of the image: the example below works fine - if the references to OpenGL are removed.

Does anyone have any suggestions of how to make these two work together without conflict ?

Thanks

Code:

import processing.opengl.*;
import hypermedia.video.*;

OpenCV opencv;

void setup() {
    opencv = new OpenCV( this );
    opencv.capture( 640, 480 );
    size( 640, 480, OPENGL); 
}

void draw() {
    background(192);
    opencv.read();           // grab frame from camera
    opencv.threshold(80);    // set black & white threshold 
    // find blobs
    Blob[] blobs = opencv.blobs( 10, width*height/2, 100, true, OpenCV.MAX_VERTICES*4 );
    // draw blob results
    noStroke();
    fill (256, 0, 0);
    for( int i=0; i<blobs.length; i++ ) {
        beginShape();
        for( int j=0; j<blobs[i].points.length; j++ ) {
            vertex( blobs[i].points[j].x, blobs[i].points[j].y );
        }
        endShape(CLOSE);
    }
}

 

Thanks for the reply... could this be a platform issue  then? Adding the OPENGL definitely creates odd triangle shapes instead of a smooth fill on my machine.
