PPT deformation animation can be used in addition to the traditional method of frame-by-frame, you can also use the PPT's own functions to achieve. Generally, it uses a frame-by-frame animation similar to animation, and a dozen slides are shared before and after to achieve the final result. To achieve the animation effect, the system home thinks that it can be realized by the PPT animation that comes with PPT. Production ideas: draw the corresponding graphics with the drawing tool, through the PPT's own gyroscopic animation to achieve the contraction effect of the line segments on both sides of the cylinder, through the enlargement /reduction animation to achieve the reduction of the cylinder bottom, and finally achieve the goal. Production process: (1) Drawing the figure The cylinder in this example is not directly drawn by the cylindrical tool in the drawing tool, but is formed by combining the ellipse and the line segment with the ellipse tool and the line tool respectively. For the convenience of description, we refer to the left line segment, the right line segment and the upper base, respectively. The gyroscopic animation in PPT, the object rotates around the center point of the object, and when the left and right segments of our graph rotate, we want to rotate around the lower endpoint. In order to solve this problem, we copy the left line segment, move the copied line segment below the original line segment, and set the line color to "Wirebar" in the "Set shape format" window. The subsequent line segment becomes transparent. Press Shift to select the original line segment and combine the original line segment with the copied transparent line segment (Figure 1). The right line segment is also processed in the same way. This step is a key step. (2) Animation 1. Select the left line segment after the combination, add the animation “Dagonal spiral”, and set the animation of “Dragon spiral” as follows: “Number”, select Custom, enter 24°( Note: This value is the number of rotations in this example. It can be adjusted according to the actual situation during the production. In addition, you must press the Enter key to confirm after input, and select “Roll-clockwise”. Press the “OK” button to close the dialog. The duration of the animation is the default of two seconds (of course, it can also be set according to actual needs). 2. The animation setting of the right line segment is similar to the setting of the left line segment. The difference is to select “counterclockwise” rotation. 3. For the animation of the upper base, we select “Zoom in/out” to set the effect of the animation as follows: Enter 0% in the “size”, that is, after the bottom is reduced, it will disappear completely. In the animation pane, set the start of the animation for the right segment and the top to be: at the same time as the previous animation. After the main animation is set, the slideshow is played, and the problem is found. There is a distance between the upper base and the line segments on both sides (Fig. 2). What is the reason for this? After analysis, the length of the line segment itself is unchanged after the rotation of the line segments on both sides, but the vertical distance becomes shorter (corresponding to the right-angled side and the oblique side of the right-angled triangle). The method is also very simple. Add a “zoom in/out” animation to the left and right side segments, and set the animation as follows. Enter 107% in the “size”, which is a small enlargement on the line segments on both sides. effect. Also, in the animation pane, set the start of both animations to be the same as the previous animation. The animation lasts for 1.5 seconds with a delay of 0.5 seconds. Play the slideshow and make a big contribution! Tip: The production of this example is done in PowerPoint 2010. The method is similar in PowerPoint 2003. The difference is that the line segments on the left and right sides must be made of rectangles, and the padding of the copied rectangle is set to “ No fill color & rdquo;, set the line to “ wireless strip color & rdquo; In addition, some animation setting data in this example can be modified according to the actual situation. If you test it several times, you will be able to achieve satisfactory results. This article comes from [System Home] www.xp85.com
