Being a powerful addition to already large set of animation tools, frame tweening can also be used to illustrate some basic animation skills.
This article discusses why some animations look tutoril and fluent while other don’t while seemingly they should have! All examples are downloadable artoonix projects, at the bottom of this page so the readers can do their own tests and experiments.
Basic concepts Effects of “positions per seconds” pps and fps Effects of linear velocity of movement Fast smooth movement. Let us work with a very simple animation of a square passing from the top-left corner of the screen to the bottom-right. It doesn’t look like much animation yet, so let us have a look at the way we can improve the situation and test various parameters introduced above.
The next example shows the same animation but with 5 frames inserted using standard tweening tool in artoonix.
The whole movement is done in 1 second meaning that there is a millisecond delay in change over of the frame. As you can see the animation is very choppy and can hardly be called “smooth”.
Let us now increase the pps to Once again, simple in artoonix – use frame tweening in the original animation and now set the frame delay to 33milliseconds to again have the movement completed in 1 second. The result is below.
It is clearly better and rather smooth. However it is not quite perfect just yet.
Artoonix – create your own animatioins
There is apparent “shadowing” in the movement which artooinx rather unpleasing to the eye. Can we improve it by further increasing the pps number? Unfortunately not – the fps is set to the maximum of 30 so whatever frames we would insert would be tutprial during export.
It has also been shown recently that 25pps is actually a very practical value for smooth animations in most cases. So what is going on here? Let us try now the next parameter – movement velocity. This clearly results in much reduced “shadowing” effect.
The answer is, in general case, “no”, as the actual perception of the movement depends on many factors, such as background elements, their relative movement, complexity of movement of the object itself and many others. However it does give a good ballpark figure of ensuring smooth motion. From wrtoonix text and examples above one could conclude that only slow animation can be smooth. It is so if only the three parameters pps, fps and velocity are considered.
Another, very important one is the actual perception of movement that is created in human visual cortex that’s a part of the brain where actual image processing artoonis done on the basis of the “frames” that eyes capture.
For instance, consider the animation below. The effect of fast movement is pretty solid, no jerkiness or other detrimental effects are visible. And yet the sequence is extremely simple – what it is exactly you tutorual see for yourself in attached to this article Artoonix project that aftoonix can download at the bottom of this page the one that is labeled “FAST”.
To conclude, it is very easy to create simple yet very effective animations in Artoonix, especially when used with frame tweening.
We have demonstrated here that a number of parameters needs to be considered and applied properly to achieve perception of a smooth animation. The complete set of artoonix projects that hutorial used in preparing this article can be downloaded here compressed with winrar, kb file.
Start experimenting yourself, and, most importantly, have fun! Smooth Movement animation Artoonix version 1. Basic concepts Effects of “positions per seconds” pps and fps Effects of linear velocity of movement Fast smooth movement Basic concepts To start off, let us introduce some terms that will be used throughout this article. This value reflects how many changes object undergoes in the animation sequence per second. For instance, in example 1 below is a 2pps animation only two positions for the sequence of 1 second.
This is a global property in artoonix and can be adjusted in main projects window “options” “Movie” tab.
By default it is set to “16”, which provides the best trade-off of quality vs. We use in this article 30fps rate unless specified otherwise. Effects of “positions per seconds” pps and fps The next example shows the same animation but with 5 frames inserted using standard tweening tool in artoonix.
Fast smooth movement From the text and examples above one could conclude that only slow animation can be smooth.
