javascript - Rotation does not change after setting transformation matrix for camera -


any idea how apply transformation matrix perspectivecamera? have transformation matrix , setting perspective camera using

camera.applymatrix(transformationmatrix);

it correctly sets camera.position camera.quaternion remains unchanged. rotation works when set camera.matrixautoupdate = false breaks trackballcontrols. have tried adding camera.updatematrix trackballcontrols again, resets rotation. have tried setting position, quaternion , scale of camera manually as:

camera.matrixautoupdate = false; camera.usequaternion = true;  var position = new three.vector3(); var quaternion = new three.quaternion(); var scale = new three.vector3(1, 1, 1); transformationmatrix.decompose(position, quaternion, scale);  camera.position.copy(position); camera.quaternion.coy(quaternion); camera.scale.copy(scale);  camera.updatematrix();

it yields same result, set correctly trackballcontrols not work.

edit: want set matrix once, not @ every frame.

inside animate loop try call camera.matrix.identity() before camera.applymatrix(transformationmatrix) , call controls.update() after camera.applymatrix(transformationmatrix):

i wondering how draw circles (or other shapes also) not instantly. so far tried drawcircle(args...) in ccdrawnode.js , drawcircle(args...) in cc.drawingprimitivecanvas class, , draw circles popping out instantly on screen. what if want achieve effect circular progressive bar, completes circle based on percentage of initialization? or more generally, if want draw circle respect prolonged period? thinking there drawcircle function elapsed time argument fail find any. or have implement own? thanks suggestions, far out of ideas. i think have implement own. think can achieve update circle drawing on each time update() function called.
