Question

As a primarily high-level/iOS dev, I\'m interested in using SceneKit for animation projects.

I\'ve been having fun with SceneKit for some months now, despite it obvi

Answer 1

It would actually be pretty easy! Here's a pseudo code of how I would do it (on the SCNView):

int numberOfFrames = 300;
int currentFrame = 0;
int framesPerSecond = 30;

-(void) renderAFrame{
    [self renderAtTime:1/framesPerSecond];

    NSImage *frame = [self snapshot];

    // save the image with the frame number in the name such as f_001.png

    currentFrame++;

    if(currentFrame < numberOfFrames){
        [self renderAFrame];
    }

}

It will output you a sequence of images, rendered at 30 frames per second, that you can import in any editing software and convert to video.
