PPT animate also plays with rotation.

  
When many people do path animation in PPT, they often encounter the problem that the object cannot automatically rotate with the curvature of the motion path. But this is easy to implement in professional animation software such as Flash. So how do you implement it in PPT? Here, I will use the demonstration of an aircraft encountered in the author's work to do the "dive & mdash; pull up" motion as an example to explore the implementation of the demonstration function. Ning folding does not turn all the way to black to insert the aircraft picture into the PPT, and add the motion curve, if the animation is played directly at this time, the screenshot of the animation process is shown in Figure 1. At this time, the nose direction of the aircraft always points to the front, and there is no change in the curvature of the path. There is a tendency to “never turn”, “and go to black”. This obviously does not conform to the law of motion of the aircraft. The direction of the nose of the aircraft should always be consistent with the tangential direction of the curve. Slightly subtotal 乖乖 Follow us to make a small change, and a small subtotal can make the animation meet our requirements. First, at the starting point, the aircraft is rotated so that the direction of the nose is approximately the same as the direction of the tangent to the starting point of the path. If our path animation is set to medium speed (2 seconds), assuming the airplane is flying at a constant speed, the approximate time to fly to the lowest point of the curve is 1 second. The following is the specific operation steps (Figure 2): select the aircraft, add "ldquo; emphasis → to the spiral" in the animation panel; set the start of the tow spiral to "before", right-click in the animation panel to select "display" Advanced schedule & rdquo; option; drag the animation start time of the gyro to 0.8 seconds; drag the end of the animation of the gyro to 1.2 seconds; change the angle of the gyro to counterclockwise 60 & deg; After this setting, if you play the animation, the screenshot of the animation process is shown in Figure 3. In this way, the movement of the aircraft meets our requirements. Through the above production, we can draw conclusions: Xiaobian recommended: "Microsoft Office 2015 download" The above method is only at the "key point"; the angle rotation by the gyro, does not make the aircraft fly in the direction of the curve tangential, But this is enough for PPT animation, and it has been visually enough to meet our needs. For more complex curve telecontrol, you can follow this method, just add a few more "key points" problem. This article comes from [System Home] www.xp85.com
