If you're tempted, please refer to my Expression Speed and Frequency Control article to see what's involved in doing it correctly. You might be tempted to simulate this bounce behavior by taking the absolute value of the oscillating sine wave (using the JavaScript Math.abs() function) and linking the frequency variable to a slider which you would keyframe to speed up. Notice that the bounces occur more frequently as the object loses energy. This waveform is generated by a bounce simulation expression. The object stops at the top of the bounce and then accelerates (due to the force of some gravity-like phenomenon), so the math involved is completely different. In fact, the bounce waveform is actually a series of parabolas of decreasing amplitude. That means a sine wave simulation is not adequate for a bounce.
As the amplitude of the bounces decrease, they happen more often. When an object bounces, it loses energy on each bounce, which affects both the amplitude and the frequency. So, you have to do the same process to smoothen your ball in order to bounce.Bounce is a completely different beast. You need to do it the same at the left side. Under the Show tab, Click the Motion Trails.Īfter Pressing S(Set key) that start from 1, you will do the same process that you will set the interval first let say at the second motion it will start at 7 then move the ball then Press S depends on your own key set interval or you copy as seen in the picture.Ĭlick the Windows Tab, in the Windows Tab choose Animation Editors then click the Graph Editor.įrom the Graph Editor, you click the Translate Y, then make a selection tool of the point interval 7 for instance,then click the Linear tangent icon where you can see the arrow pointed on it in the picture.Īfter clicking the Linear tangent, select the right line as you can see in the picture then right click, then choose break tangents then move the line.
Note: You can adjust the height of the object depends on your own style.Ĭlick the Visualize tab then choose Create Editable Motion Trail. Press spacebar and go to Front view, Press S(Set Key) in the Time Slider start from 1.
Press again the W(Moving tool) upward as seen in the picture. Press W(Moving tool) then click the yellow arrow to move the object slightly upward just above the grid in the Perspective view. Under Polygons tab, click the polysphere. Hi everyone!! I've here a step by step tutorial on how to animate a bouncing ball using Maya 2017.
