Hi,
Stuck with 3D headings. I have 3D cone (ofConePrimitive), which moves with following algorithms:
ofPoint pos;
ofPoint axisX, axisY, axisZ;
float gap = 5.0;
in setup():
cone.set(20, 80);
pos = ofPoint( 0, 0, 0 );
axisX = ofPoint( 1, 0, 0 );
axisY = ofPoint( 0, 1, 0 );
axisZ = ofPoint( 0, 0, 1 );
in update():
float time = ofGetElapsedTimef();
float twistAngle = 5.0 * ofSignedNoise( time * 0.3 + 332.4 );
float rotateAngle = 1.5;
axisX.rotate( twistAngle, axisZ );
axisY.rotate( twistAngle, axisZ );
axisX.rotate( rotateAngle, axisY );
axisZ.rotate( rotateAngle, axisY );
pos += axisZ * gap;
cone.setPosition(pos);
in draw():
cone.draw();
What I need and I couldn’t figure out how to make cone heading its movement.’
In other words, its tip (highest point) should be always directed forward.
