I haven’t tried to tweak the cue ball sudden slowing on collision with the red ball, but it should be simply a matter of putting in another key and reducing the slope of the curve at the collision frame. The speed curve is simple enough to tweak, though, to get an initial high speed and constant slowing throughout the entire path. It defaults to bezier, handles locked, which means the ball speeds up at the beginning, runs at constant speed for most of the path, then slows down at the end. This would be the appropriate place to do the tweaking. Not to critique the physics, but there is also a Path IPO, which deals simply with speed. I’ll put them on a separate layer so I can make them dissappear during the render. I haven’t done it yet, but I am going to use those sticks as visual aids when I adjust the ipo curves to make the balls slow continuously along the entire path. So to make a nice slowdown, the bezier handle from the beginning of the run must have a slightly steeper slope than the ending handle, and the handle after the bounce must be shallower still, since the ball travels more slowly leaving the collision than entering. It looks like the slope of the bezier curve handle is the speed of the ball along that axis at that point. In koots2’s ipo curves, he’s got a nice slowdown, because the two ipo curves have the same shape, even though one is upside down. Since I’m assuming no spin on the ball, the red and white ball bounce off the bumpers at the same angle they hit, just on the opposite side (yellow and blue line.) ![]() When it contacts the red ball, the red ball moves away on a line connecting the centers of the two balls (the red line.) The white ball moves away on a line perpendicular to the red line (the green line.)

If you just draw key frames and then push them around you generally end up with animation that looks like a computer did it. FlipBook is for real animators who want to do real animation. "Comment on "Don Bluth Recommends DigiCel FlipBook" ". Credits and endorsements įlipBook has been used on Titan A.E., The Simpsons Movie, Enchanted, The Princess and the Frog and others, and has been endorsed by Don Bluth. ![]() Ī free, full-featured demo version which produces watermarked output is also available for download. ![]() Digicel Flipbook does not work on MacOS after Catalina (2019) but there is a version called DigiCel Flip-Pad which runs on iOS for iPad. The other editions support more layers, more frames, multiple soundtracks and higher output resolutions. The Lite edition supports one foreground and one background layer, one soundtrack, and up to three hundred frames per shot. Versions įlipBook is available in four versions: Lite, Studio, Pro and Pro HD. Each frame must be drawn separately FlipBook intentionally does not support skeletal animation or morph target animation, as these are not part of the traditional animator's toolkit. Inbetweening is done using onion skinning. In either case, the internal format is raster-based, not vector-based. It is intended to closely replicate the traditional animation process, very similar to the likes of TVPaint Animation and Toon Boom Harmony.įlipBook supports scanning physical drawings with a TWAIN-compliant scanner or webcam, or direct digital input via a Wacom tablet. There is a version for iOS called Digicel Flip-Pad. (runs on MacOS Mojave or earlier, but not on recent MacOS Catalina, Big Sur, Monterey ). ![]() DigiCel FlipBook is 2D animation software that runs on Microsoft Windows or Mac OS X.
