Example ONE: The bouncing cylinder
【Steps】
-
Insert shape > Circle > Format > Shape Effects > 3-D Options, set the top bevel (Height: 300 pt.)
-
Copy this circle and perform 3-D Rotation and set perspective value
-
Set the parameters of Tween Animation
You need the check and set the [Duration]
Align the shapes by using the alignment tool, then start the slide show to see the cool effect
-
Select the shapes need to be aligned
-
Click Format > Align, then choose [Align Center] and [Align Middle] respectively, the shapes will overlap completely
【Shape + Color】: Set Tween Animation
【Note】To use [Tween Animation] to achieve variant animations, you need to use the shape with handle in PowerPoint’s shape options
【Shape + Color + Transparency】: Set Tween Animation
Example TWO: Picture Gradient Mask
Please check the following gif for specific operation. We don’t need to add animation in this example, so don’t check [Duration] when setting the Tween Animation parameters.
