I’m struggling with ofxARKit…
I guess the current frame anchors increase automatically and each of them has a matrix to transform.
Btw how can I access them to iterate the other objects.
example code is below.
for (int i = 0; i < session.currentFrame.anchors.count; i++){
ARAnchor * anchor = session.currentFrame.anchors[i];
// note - if you need to differentiate between different types of anchors, there is a
// "isKindOfClass" method in objective-c that could be used. For example, if you wanted to
// check for a Plane anchor, you could put this in an if statement.
// if([anchor isKindOfClass:[ARPlaneAnchor class]]) { // do something if we find a plane anchor}
// Not important for this example but something good to remember.
ofPushMatrix();
ofMatrix4x4 mat = ARCommon::convert<matrix_float4x4, ofMatrix4x4>(anchor.transform);
ofMultMatrix(mat);
ofSetColor(255);
ofRotate(90,0,0,1);
img.draw(-0.025 / 2, -0.025 / 2,0.025,0.025);
ofPopMatrix();
}
I wanna do like below.
As I said above current frame anchors increase automatically so “out of index” error happens…
for (int i = 0; i < session.currentFrame.anchors.count; i++){
img[i].draw();
}
Does anyone have an idea?
